ONEUP CARBON BARS. Strong, lightweight & vertically compliant.
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, minimizes arm pump and vibration and maximize steering response. 35 done right.
Almost every other carbon bar on the market copies the simple tapered profile of an Aluminum 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 "optimize" the flex slightly with layup, but geometry is king and you're fighting a losing battle.
The OneUp bar profile minimizes 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 benchmarked the OneUp bar against the most popular carbon bars on the market as well as foam filled aluminum 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.

With a lifetime of experience of riding and winning on trails and racecourses around the world, the Ritchey tradition of designing ideal handlebars continues with the introduction of the Comp 10D Rizer.
Taking inspiration from the original XC 10D flat bar, this 800mm-wide trail bar offers a generous 10° backsweep for perfect wrist alignment, 4° upsweep to reduce pressure on the outside of the hand, and 20mm rise for optimum positioning.
All of this combines to deliver a uniquely comfortable and controllable mountain bike experience. Whether ripping your favorite trails from Moab to Houffalize or your local runs, the Ritchey Comp 10D Rizer bar will help deliver a lifetime of great mountain bike experiences.
