The OneUp Carbon Handlebars are designed to provide the best riding experience. The patent pending oval shape of the bar combines the best of 31.8mm and 35mm standards, making it strong, lightweight, and minimizing arm pump and vibration while maximizing steering response.
Unlike other carbon bars that follow the simple tapered profile of aluminum bars, OneUp leverages the benefits of carbon by creating a more complex shape for better performance. If you prioritize bar compliance, the regular 35mm diameter bar is not the solution. Attempting to optimize flex through layup only goes so far.
The OneUp bar minimizes the 35mm diameter clamping area, which is the stiffest portion of any 35mm bar. It then transitions to a flattened, oval shape and finally to a standard 22.2mm clamp diameter for the control zone.
Compared to popular carbon bars and foam-filled aluminum bars, OneUp showed an average 21% increase in vertical compliance and 28% increase in steering stiffness. These are not just small improvements.
The 35mm diameter standard has not had a good reputation, until now. The new OneUp Carbon Handlebar sets a new standard for 35 Dia.
OneUp Handlebar Decal Kits are sold separately
