Nothing beats riding packless, and the OneUp Components EDC tool system helps in that quest. It allows you to carry all the tools and small misc parts either in a mini pump or more excitingly, inside your forks steerer tube. But how does it work? Is it any good? and who is it for?
ARTICLE 1.3.007“Bicycles and their accessories shall be of a type that is sold for use by anyone practising cycling as a sport. “
So the Athertons have a launched a bike brand, sort of. Robot Bikes Co has emerged butterfly-like from its chrysalis and has unveiled itself with Atherton winningness on the head badge. But is this just a cash in on their brand whilst Rachel is still at the height of her career as Gee’s star is on the fading side of his? Or could it something else, or both?
I have previously mused on the UCI article 1.3.007 and how it requires all bikes raced to be available for purchase by anyone. I am of the mind that this, in fact, stifles bike development. This requirement for a race bike, means that compromises must be made if the bike raced is for mass public consumption.
If you built a bike that was a pure race only machine, it would probably have quite a high cost of entry regarding the skills required to pilot it. Race teams are primo marketing for a bike company. So the ability for the man on the street to buy the same bike as the racers they follow is a big draw. It is also one of the things that makes bike racing unique compared to automotive racing. But does it make for better racing? Yes and no.
If teams were able to race custom built machines never intended for public consumption, like F1 or WRC. Then the teams with the deepest pockets would win. But it means that top tier racers are always fighting with bike fit and suspension kinematics. There is only so much you can do to make a frame fit with anglesets and custom linkages, this is only exacerbated when your over 6 foot.
So how do the Athertons and Robot, I mean, Atherton bikes come into this train of thought? This could be next level thinking to work within the UCI rules and still ride the perfect tailored race bike.
Robot Bike Co’s USP was their method of manufacture and their offer of custom geometry. By using sintering additive manufacture (3D printing in metal), they were able to make each bike to order, exactly to your bodies measurements. They were a tailored suit in a world of off the peg frames.
So acquired, re-branded and re-launched as Atherton Bikes means Rach, Gee and not forgetting Dan, now have the ability to have the perfect fitting bike, with the exact geometry they need. The kinematics or reach not working out? Then a new front triangle or linkage can be fabricated between races, it can be that quick.
Selling direct to consumer, they can then offer the “Gee Bike” or the “Mere Mortal” editions of their frames. If each bike is a custom piece, then they can constantly evolve and adjust the design betweeen races. Just like F1, which is funny as two of the founders of Robot work in F1.
So are the Atherton’s cashing in on their brand? Well maybe, but who can blame them, Peaties been selling unicorn jizz in his retirement afterall. But is this a next level strategy crossing over from motorsport into DH? Maybe, just maybe.
You know that little switch on your clutch mech? That magic little mute button? Well does that clutch affect your suspension?
I had a hunch that the clutch on my mech was inhibiting the initial movement of my rear suspension. We already know that anti-squat (pedalling) and anti-rise (braking) affect the suspension ability to do its job properly. So it is only a small leap of logic to assume that the clutch inhibiting your mechs movement, (thus affecting chain growth) is adding to that mix.
I’d proposed this question a few times and was always met with two responses;
“There are bigger influencing forces, like rocks on the trail! The clutch exerts such a small amount of force that it makes no difference!”
So with no way to prove or disprove my hypothesis the debate always ended there, that is until I had an extended loan of a Shock Wiz. The Shock Wiz is a suspension setup aid, it plumbs into the air valve of air forks and shocks, monitors them on the trail and offers setup advice and feedback. With the latest update to the app, this little unit now offers a far more nuanced tool for suspension tuning. It also offered the opportunity to experiment and get some data to further my curiosity on the subject.
Time for the science bit.
The experiment was simple, I had gotten my Shock Wiz score to 88% and I was feeling pretty happy with how it was all feeling. I would do a control run of a fairly typical piece of natural Scottish single track, then again with the clutch switched off. This direct comparison would show if the Shock Wiz detected a difference in the shocks behaviour.
The test track was a lovely little ribbon of prime condition singletrack on the southern edge of Aberfeldy. Comprising of fast and pedally sprint sections, drops and root matrices, so providing a good variety of trail conditions to test on. After a few runs it was time to consult the app and see if the Wiz had noticed a difference.
My prediction was that the Shock Wiz score would decrease and the low speed compression would need increased by a few clicks and maybe a few more PSI in the air spring. My thinking being that the clutch would inhibit rider induced movement and would be more active to small bump input.
So in short, yes the derailleur clutch does impact the suspension,
Suggestions with clutch
All good on the detections
Whilst the suggestion after the first run was that with the easier breakaway more air pressure was required, however after successive runs it settled back to the green. So, my prediction was partially right, the compression was affected, but it was in the high-speed over my predicted low. So in short, yes the derailleur clutch does impact the suspension, now the question was, how much of an impact does it actually make?
Well the initial suggestion, with the mech activated was that the high-speed was far too firm, listed fully in the red. So by the apps measure, it needed adjusted by three or more clicks softer. Now the Cane Creek Inline, has an adjustment range of four full turns on HSC. So if we take one half turn to equate to one click of adjustment, three or more clicks is a significant tweak that the app is looking to make.
Improvements on highspeed more than low speed.
No change here.
However with the clutch turned off the app was only looking to make an adjustment of one to two clicks, so maybe a single half turn. That is more or less in the right ball park in my view.
Something that I did find interesting, is the lack of a braking shudder feedback that I experienced with the clutch turn off. With the clutch on, when I was at full chatt through a rock garden I had significant shudder from my rear brake. My reckoning was that this was my shock and clutch fighting it out due to brake jack. With the clutch no longer fighting the HSC the shudder didn’t occur. Shock was able to do its job and the bike just monster trucked along.
Did it make a difference to what I experienced as a rider? In some circumstances.
Was the bike louder? Well, yes.
Did I drop a chain? No, I have a chain guide and narrow wide front chain ring for that.
Did the the app measure an improvement with it turned off? Yes, the tuning score improved by 5%.
Will I run the mech with it switched off form now on? In some circumstances, yes I will.
Will this be a definitive answer to this question on STW? HAHAHAHAHAHAAHAAA, sorry was that a serious question?
Everybody knows 29ers are faster-rolling race winning wunder machines. But should you be riding one? Should we start to think about wheel size in the same way we think about frame size? ie, the taller you are the bigger the wheel size you ride?
In this Vlog I thrash the question out to start bit of a discussion
New standards, everybody loves them, wait no the other one, nobody loves them. Pink bike keyboard warriors love them, nothing gets them going like a new axle width. What do I think, well, I don’t care and neither should you.
This little shed based rant/vlog I cover the ground I previously wrote about in this post.
Co2 cartridges, small, light and fast. Its like they come from the future. But I’m increasingly not a fan. Here is why I don’t trust Co2 carts as far as I can throw them, and I have a terrible throwing arm.
Everyone has a local spot, it might need a drive to get there but it is their default place for riding.
For many people these are local woods or, if they are lucky, a trail centre. There aren’t any full sized trail centres in Aberdeenshire, but that doesn’t mean we are lacking riding spots. My local spot is Scolty, or Hill of Goauch (depending on what side you start on).
Because it is my local, I never really think to write ride or trail reports about it as a location for riding, but that is doing it a disservice. I have written posts on other topics that were inspired by riding there, but never about the hill itself.
So here is a long overdue trail review of one of Aberdeenshire’s more popular spots.
On the outskirts of Banchory, nestled between the river Dee to it’s north and farmland to it’s south. Scolty is a large woodland covering two main hills with a heath land saddle spanning the two.
People have been riding bikes here for a very, very long time, and the wealth and breadth of the trail network is testament to that and the years of work by local builders. The trails mostly converge on two hills, Scolty and Hill of Goauch.
Radiating out form the tower at the top, this hill has arguably the greater density of trails. Historically this is where the downhill trails were and they can be broadly characterised by being both short and steep. That is not to say that variety cannot be found here too. From trails that are flowy crafted berms through to natural thin flat cornered ribbons, you can even find big drops and hucks all on this modest sized hill.
Downhill from The Tower
Nice bit of tech
Goauch is a little further out and has trails that have a subtlety different feel, if I was introducing someone to the hill I would say that this side had the “enduro” trails. The trails start to get longer, tighter and more ruddered in. There is some properly technical riding to be found here.
Hill of Goauch “XC” trails
The trails tend to have a good mix of flat out speed, awkward slow technical corners and with plenty of sneaky drops and chutes. In the wet the place can be a real warzone but in the dry the riding is superlative.
Tree Hugging Hippy
Steep roll in
Cheeky wee down
Descent times start to creep up as well, with some trails having deviations or can be tagged together to get upwards of 8 to 10 minutes of down time. That being said, the more down, the more you have to climb back up. There are also plenty of features all over the hill to scare yourself on and get the adrenaline pumping. Something that the builders have been really creative in joining up in places.
Looks innocent at the start
The thing that unites all these trails is their full gas nature, Scolty and Goauch are not a place for cruisy trails. This is not somewhere you ride if you want a blue or straightforward red, here you need to keep your wits about you and the best thing to do is to commit and attack.
This makes it a great venue for progression, my riding progressed faster than at any other point once I moved to within 15 minutes riding of these woods. I crashed more, broke more components, learned more about terrain and bike set-up in one year, than I had in the previous three.
Trails I have ridden regularly for 4 years still surprise me, the natural shifting and evolution that typifies natural riding keeps things exciting and unpredictable. A day without a botched run or at least a near miss is a day when your not riding fast enough. Once you can consistently and cleanly ride a trail, there is always another, more technical line just down the fire road to keep the challenge high. The satisfaction of getting a PB (sorry Strava) is so great as to keep you coming back thirsty for more and to try and finally clean that trail that has been scaring you.
(depending on what side you approach the hill), is a hidden gem in the southern edges of Aberdeenshire.
From the steep old growth of Drumtochty Glen, to the tight dark stands on the Auchenblae side, this hill has a lot of character and range of trails on offer. For the committed downhill rider and enduronaut the Drumtochty slopes provide plenty of challenge and speed for those willing to tame the gnar. On the mellower side of things, the tight trails of the Auchenblae side are woven over and through deep furrows cut between dense crops of pine trees, on ground that is apparently impervious to rain.
The fire road climbs snake lazily upwards and is dispatched without much fuss allowing the main business of descending to soon begin. The “trail” singletrack on the Auchenblae side of the hill provides singletrack with a character quite different to offerings elsewhere in the region. The dense growth of harvest timber has led to quite a barren understory, that is both fast draining and thick with the loam created by years of shed pine needles.
These trails are short fun blasts that reward the committed who work their body english as much as they turn the cranks. They can be linked together to create long flowing runs that build in pace the further you run, before breaking the tree line and climbing back up the fireroad for another blast on the roller coaster.
The impossibly weather proofed trails have a deep soft loam that rips into high roster tails as you bob and weave between the furrows. Yet with all that grip, sniper roots still lurk in the shadowy corners waiting to grab a wheel out from under you and set you pin balling from side to side down the trail.
Then there are the longer newly dug steep “enduro” lines. Off camber, with steep chutes and rooty drops. The newer lines are best attempted with repeat viewings, as once on the bike blind drops always appear larger than they are in reality.
You can’t simply steam roller these trails if you want to go fast.
The proximity of the trails to each other and the modest climbs of the hill may lead you to expect a less demanding character of singletrack. Yet a trail can be as challenging as you make it, with precision and bike handling levels increasing dramatically the faster you go. You can’t simply steam roller these trails if you want to go fast.
It may not have the number and length of the trails at other local spots like Scolty, but this is one hill not to be overlooked.
It was the Saturday evening after his World Championship winning run, they had T-Shirts for sale at the Mondraker pits. Danny Hart on the Front and Redcar Rocket it on the back, they were pretty special and very cool, only being for sale there and then. Thing is, I wasn’t in Val De Sole.
I saw a post he put on his facebook page briefly mentioning the T-Shirts, I thought I would join in with the social media storm and send Danny a short message wishing him luck and cheekily asking if I could buy one of the shirts. I thought little of this and did not expect a reply.
To my complete surprise, a few days after his win, he replied.
I like many other fans watched the live feed with building anticipation and excitement, it was a hard track, one that had taken out some of the sports very best. With rider after rider coming down the hill the tension grew and would surely get to our man. Then Harts run came, the beeps counted down and he threw himself at the course. Equal parts perfect precision and on the absolute ragged edge, it was a run that you couldn’t believe was happening. Then when he crossed the line and the light went green, a cool shirt became a prized piece of memorabilia. And to my complete surprise, a few days after his win, he replied.
A few quick messages and a Paypal transfer later and one of the shirts was mine. Now this might not seem like a big deal, it is after all, just a T-shirt but it is symptomatic of a few things in our sport, both very very good and really quite bad.
The level of access between the top players of our sport and the normal rider is almost unparalleled. Events like the Fox Hunts and Peaty’s Steel City Down Hill race are a prime example of this, what other sport can a normal rider rock up to and race the current world champion and other top tier legends? The barriers between the public and the pro’s are so small as to almost not exist. You you can visit the pits and watch the wrenches and support crew prep the racers on race morning.
Now DH is like the F1 of mountain biking and when you compare the access between them it is quite startling, but truly refreshing and something that our sport should be applauded.
And sadly, me buying a shirt from Hart via Facebook is also practically like buying merchandise from the lead singer of a band outside of a small venue gig, except he is the reigning world champion. The fact that our sport is, relatively speaking, cash poor when it comes to the pros salaries and bonuses is a travesty. Even for the biggest names. Now Hart wasn’t selling the shirts to put some money in the meter, he does it because he a humble down to earth guy who takes time for his fans and supporters. But many racers sell similar wares because they need to fund the vans drive to the next round of the season.
I would hope that if downhill was ever televised again and money came into the sport, that it would filter down to the riders, and that the velvet rope of other sports (and cycling disciplines) wouldn’t descend between rider and fan.
It’s great when you can travel from home to a race, you have all the support and kit there to help set you up for a great day on the bike. But more often than not you have to travel, and as the adage goes, failing to prepare is preparing to fail, sorry, Boy Scout.
Preparing for a race covers a whole host of elements, from physical training and mental preparation, bike prep, nutrition through to travel and accomodation logistics to name but a few. In this post I’m going to cover the week running up to a big race, what I do to prepare and when, as well as outlining my race day routine running up to the start line.
7 Days to go
With 7 days to race day, chances are it is the weekend, you might want to get one last big training ride in before resting up over the coming week. Conveniently the weekend also gives you plenty of time to get your bike race ready, a good place to start is with my earlier post on race Bike prep.
Hopefully your bike received the all clear, however if anything has been flagged up as needing replaced then you have the time to order any new parts to get your steed back to full health before the race weekend.
On a side note, try not to stack it in the week running up to a race, just a suggestion.
Other things to do are to ensure any travel and accommodation arrangements are made and you know how to get there, you don’t want a stressful drive to ruin to start of your race experience, after all its meant to be fun!
3 Days to go
With 3 days to go your training should be in full taper mode, so instead of lounging on the sofa its time to pack your race kit. This is a basic list and should only be used as a starting point. It is always better to pack something and leave it in the car than have to scrounge around the carpark for a bottom bracket tool 30 minutes before the start of the race!
Knee pads and armour if it is a gravity race
Shorts and Bib if you are so inclined
Winter/rain clothes (being caught off-guard can make for a miserable race) including base layer, arm/leg warmers, etc.
Post-race, warm change of clothes (change out of chamois as soon as you can)
Back pack (if using one)
Bottles, use N+1 to work out how many you need
Heart rate strap (if you use one)
Post-race recovery drink/snack
Post race beer (if not driving)
Electrolyte drink or tabs
Plenty of water
Spare wheels ready to race
Cycling computer (if you use one)
Bike floor pump
Tools: Ensure you have tools for all parts of your bike, bare minimum take, Allen key multi-tool, flathead & Phillips screwdrivers, electrical tape
Spare tubes, tire levers & CO2
With your race kit packed its time to give the bike one last check. This is especially important if you needed to order any parts for your race bike after its thorough going over earlier in the week.
So you’ve traveled to the race venue and got your self settled into your dig’s, tomorrows the big race and its time for the race routine to kick in. Not staying at the race venue and traveling the morning of the race? No problem just just do the final count down at home.
If at the venue and its possible, go check out the course, if its a downhill, go walk the track, if its a XC race go walk or ride a lap.
Time to eat, carb load like crazy, pasta and a lean protein like chicken or tuna is a great place to start. Don’t over do it and don’t eat anything that your not familiar with the last thing you need is stomach issues from a dodgy curry, keep simple and carb filled. Lay you race day kit out, pack your back pack if you are using one, set your bottles or hydration pack out, you know it’s all fine as you checked it when you packed it on day three but peace of mind leads to a good sleep and rest is important.
Breakfast time! this meal sets you up for your race so make it count! A balanced mix of slow release carbs and some protein for the win. So a big bowl of porridge followed by a fruit salad with some greek yoghurt and coffee for me. Some people like eggs as well, but I’m not an egg guy.
Hydration before your race is just as important as during your race, make sure you include electrolyte drinks in your pre-race hydration especially if its a warm day.
Get to the race venue good and early with at least an hour to spare, as soon as you arrive get yourself registered and collect your race number.
Run through the final check list
Tires pumped and pressure checked
Computer on bike and HR monitor on
All the food you need
All multi tools and spares needed packed
Allow time for a proper warm up, stretch up slowly working through all the major muscle groups, a quality warm up should take at least 30 minutes. Do some sprints as well as some climbing where possible, the more intense the race is from the gun the more intense the warm up should be.
The hour before your start time have a final snack, a banana or a gel with caffeine is ideal.
Get yourself to the start line early and get a good position if its a mass start, if the race has a staggered start then be early for your start time.
An iconic Aberdeenshire hill with a wild and punishing descent, a loop of Clachnaben is nothing short of a mini epic.
We all love wild natural rides, big days on big hills with big distances. But sometimes you want the feeling of remote riding and the challenge of truly rugged terrain, but only have a few hours to spare.
With its distinctive tor of rock visible from as far as Aberdeen, Clachnaben is a popular hill for walkers and trail runners. It benefits from a well maintained path, with substantial water bars and when required, uneven but substantial stairs. Which comes as a welcome relief as the sustained climb hovers between 15% to over 25% gradient. Once at the top looking down, when that gradient starts being measured in the negative, it becomes one beast of a descent.
It is a modest loop when measured in kilometres, at 15.7km its not that far. But when you take into account the 582m elevation gain, it takes on a much more formidable guise.
The loop starts in the walkers carpark and rounds the shoulder of the hill. Climbing from the rear so to speak, before topping out west of the summit. Then downhill essentially all the way back to the carpark.
I was blessed with blue skies and temperatures in the 20’s, the ground was baked dry and dusty with a light (for now) wind keeping things tolerable.
Following the course of the river into Glen Dye, the first leg was a fairly sedate and fast spin on smooth fire road. Its not long before I reached the natural rest break of the Charr Bothy. Worth a visit as part of a longer trip, today it merely provided me with some shade before rallying myself for the climb.
The climb is a hard one, the sandy track giving little traction with a slow zig-zagging grind being the only option. It starts as it means to continue, with the gradient rarely straying out of the low 20%’s. Gradient isn’t usually a measurement mountain bikers concern themselves with, its a “Roadie thing”, but its something that you come to fully appreciate whilst on this trail.
The traction slipped away in little roosts of sand
The heats oppression was only slightly moderated by the wind that started to grow with the Elevation. The traction slipped away in little roosts of sand with each pedal stroke as my resolve to stay in the saddle started to slip away. My heart rate monitor (a very thoughtful gift from my wife) was not needed to tell me how hard my heart was working, I knew how hard it was working as I tried to breathe through the work.
Stalling out completely on the loose sand, I was glad of the rest and resigned myself to push the rest of the way. It was not far before a reminder (if one were needed) that the climb is a suitable challenge for even motorised vehicles.
Peering over the heather the frame of a crashed WW2 aircraft stands in equal parts of rusting steel and immaculate aluminium. The wreckage, deemed to difficult and costly to remove, has been left for time and the elements to reclaim. Crash sites from this period are a surprisingly common feature of our hillsides, but serve as a poignant reminder of past sacrifices.
The final push of the climb was a more forgiving affair, with slight undulations and short downs giving free speed for the next up. Hauling myself to the top, the view offered a suitable reward for my efforts, literally being able to see my house from here.
My first run of the day is usually a bust. Its not that I’m not warmed up physically, but it usually takes me at least one trail to both sharpen up and loosen off. Not a luxury availabile on this ride, in front of me lay a 2.2km descent that I had to get right first time.
Starting with a technical mine field of rocky steps and water bars followed by drifty sandy trails and narrow steps with genuine exposure at times. All this before entering a rooty narrow wooded section with blind turns that are usually occupied by sheep and/or ramblers.
At this point in a post you might expect to find a POV video of the descent, a short edit of the day perhaps. Due my own ham fistedness, I managed to turn my Drift camera’s lens into portrait mode, smooth. So stills it is.
Breathing deeply in and out, it was time to clip in.
Rolling in slowly the granite steps were an uneven jumble of square edged drops and awkward turns, staying as light as I dared on the brakes, the key was to keep momentum. The grip of the granite slabs became punctuated with sandy trail, the acceleration was incredible, as soon as I stopped feathering the anchors the bike just took off.
The back end let loose on the corners, the rear tyre buzzing the heather as I relied on the bike to find grip. Bunny hopping water bars and looking as far down trail as I could, I rounded the shoulder of the hill. Taking on a series of exposed narrow stairs it was slow in and fast out.
the prolonged descent had steam practically pouring from the pistons
The brakes were starting to lose their edge, the prolonged descent had steam practically pouring from the pistons as the tree line fast approached.
A robust lattice work of roots encroached on the trail, the game changed as I entered the wooded section that was more within my comfort zone. Letting completely loose the anchors I was popping over the roots and down drops, this short section was over far too soon as it has real rhythm and pace, when dry. All this fun comes to an end when you reach a deer fence, a quick hop over a stile followed by a mellow pedal for the final push back to the carpark.
A clean run, no matter how fast, on this EWS worthy trails always delivers a sense accomplishment and adrenalin that only comes from a mountain bike.
Your strengths are those you practice most, and your weaknesses those that are too hard or to rare an opportunity to perform.
A few things have caused my riding to change and progress over the years, one of the biggest influences has been the local loop. We all have a local loop, somewhere we can crank straight from the house or after a short drive, long drives eat into riding time. What the local terrain has on offer and the style of the trails to be had there will dictate the strengths and weaknesses of your riding (unless you travel to ride a broader variety).
Whilst on a skills course aimed at steep and natural terrain I was told that I was riding with an XC style. This didn’t surprise me all that much, as my local loop for most of my time on a bike had been just that, cross country. My strengths on the bike reflected this, as did my weaknesses.
Strong in the climbs, fast on undulating terrain where constant power is needed and trails with climbs or sprints in them. Conversely I was slow on steep terrain, lacking in confidence with jumps and drops, and relied to much on my fitness to build and keep speed.
This started to change a few years ago when after moving house my local loop changed, I went from averaging 160m of elevation in 10km to 260m in 10km. The change of local riding spot had a pronounced effect on my riding, but it was not without teething problems. Crashes, broken bike parts and sliced tyres, as not only did my skill level have to adapt to the more technical terrain but my bike setup had to change too. The challenge was rewarding and riding bike became thrilling again and not just a test of physical ability.
My progression was apparent when I next visited Glentress with my brother, who traditionally I had always been chasing. My new local loop had been beasting me for a few months by this point and I was now out in front, my power in the climbs had also grown as the greater elevation had made an impact.
However I still found myself chasing the pack whilst on my LBS shop rides, when I realised, I was on the groups local loop, not mine. When on home turf you are faster, more confident and have the trails memorised. When on unfamiliar trails its a new learning curve, new challenges and new terrain to master.
There will always be scope for improvement on your local trails but variety is the spice of life after all. I try to mix it up with as broad a variety of trails as possible but time spent traveling is time spent not riding. My local loop has taught me a lot, and has many lesson still to school me. But weaknesses still remain and new ones have been brought to light, and again they reflect my local loop.
So the only way to address those is ride somewhere that forces me to address those weaknesses and gives me the scope to progress those elements of my riding, making me a faster and more rounded rider.
But and hours driving is an hour not riding, its a tough call sometimes.
There are some things that are constant, they may evolve but can you reinvent the wheel?
I have been curious to try oval chain rings ever since reading an excellent article about them a while back on James Wilson’s site. Now, thanks to my support from absoluteBLACK I have one of their oval chain rings to find out for myself.
Off round chain rings are not a new idea, back in the late 80’s Shimano championed their Biopace system. Seriously flawed, users complained of knee and joint pain. Time has thankfully moved on, and the oval chain ring is not the oval ring of the past. AbsoluteBLACK’s offers gains and benefits over conventional round rings.
“Absolute Black oval chainrings deliver power more smoothly to your rear wheel. This means you are better able to generate and maintain, constant cadence. Because oval chainrings reduce the peak loads on knee joints, riders using them get less stress on the joints (knees) and therefore are able to keep certain level of effort for longer. This results in higher average speed.” (source absoluteBLACK.cc)
With the timing and shape being completely different to that of the Biopace rings, comparisons between them are less apples and oranges and more like apples and tuna.
Out of the package it was immediately obvious these were not your average narrow wide chain rings. The oval shape was subtle, but enough to make you look twice if you didn’t know it was not a round chain ring. The asymmetric tooth profile is superbly detailed and shaped to hold the chain and move dirt and oil off of the tooth’s face.
AbsoluteBLACK offer a 30 day trail period, if oval is not for you they will swap it for a round one; as a brand ambassador I was still more than ready to make use of this trial period.
Assymetric tooth profile.
Impeccable CNC machining.
Fitting the ring was a straightforward affair with the 32 tooth ring having built in threads, once on and with a fresh new chain it certainly scored in the good looks department. One thing to note is if you are running a top guide, make sure to adjust and check the height of it to avoid it hitting on the high point of the oval!
It was time to hit the trails and to see how the theory applied to reality. The initial test ride would be on some newly cut trails that were steep and loamy, hitting them blind would mean drive train worries would need to be the last thing on my mind.
Clipping in I was expecting to feel something very pronounced through the pedals, a pulsing in the torque. Being completely honest, it felt natural, very quickly it didn’t feel strange at all and most importantly I noticed I was losing my fellow riders on the fire road climbs.
It encouraged a smooth, even pedal stroke, but it still felt good even at lower cadences, one thing I was concerned about was that it would have a “sweet spot” in terms of cadence, but it just doesn’t.
When the terrain turned steep it again performed flawlessly, we have all gotten used to not dropping chains thanks to 1X and narrow wide chain rings, in this regard the oval ring performs perfectly and inspires confidence in your drive train. On more pedally trails the extra gains in power and torque led to faster acceleration and less fatigue in the legs.
My initial feelings are that I will not be needing the 30 day trial offer, the additional power in the strong part of the pedal stroke provides a noticeable enhancement to performance and encourages a smooth pedal technique. Long term durability is not a concern as the build quality is just so good, with the grinding paste of Scottish dirt doing nothing to take the shine off of the teeth’s anodizing.
I’ll no doubt be returning with some long term assessments once I have a few months of turning oval under the belt, but for now I can certainly recommend them.
The rains have eased, the waters may have subsided, but the trails are still saturated.
The heavy sodden ground can be a blessing and a curse, the falling mercury freezing the ground hard and fast rolling. As the thaw creeps in and the ground softens, traction is easy to find, but too far into the melt and a mud bath ensues – you can’t have it all.
It was a month of regular rides and of building pace, revisiting old trails, riding them in a way that only served as a reminder of lost speed and gains to be made.
