The goal for the new OneUp Carbon Handlebars was to make the best feeling bar possible, something which would let us ride harder for longer.
The solution is our patent pending oval shape which combines the best ride characteristics of 31.8mm and 35mm bar standards into one package. This is the most comfortable bar we’ve ever ridden, period. It's strong, lightweight, minimises arm pump and vibration and maximise steering response. 35 done right.
Almost every other carbon bar on the market copies the simple tapered profile of an Aluminium bar. With carbon you can take advantage of more complex shapes to get a better performing product, so that's what we did. If you actually care about bar compliance, then you don't make a regular 35mm diameter bar. Sure you can try to "optimise" the flex slightly with layup, but geometry is king and you're fighting a losing battle.
The OneUp bar profile minimises the length of the 35 diameter clamping area as this is the stiffest portion of any 35 diameter bar. The 35mm clamp diameter quickly changes to a flattened, oval shape in the transition zone and then to a standard 22.2mm clamp diameter for the control zone.
We bench marked the OneUp bar against the most popular carbon bars on the market as well as foam filled aluminium bars. The results were, on average, a 21% increase in vertical compliance (comfort) coupled with a 28% increase in steering stiffness (responsiveness). These are more than just marginal gains.
Until now the 35mm diameter standard has had a bad reputation and rightly so. This is 35 Dia. done right.
