A High-Quality Bar For A High-Performance Ride

Even though 35mm handlebars have become pervasive in the mountain bike world, they can often feel too harsh during a full day of riding rough trails. OneUp claims to have solved this problem with the Carbon Rider Bar, the ultimate add-on to make your bike run smoother than ever.

A unique patent-pending flattened oval shape delivers just the right amount of vertical compliance, combining the best characteristics of 31.8mm and 35.0mm diameter handlebar standards. This one-of-a-kind profile increases steering responsiveness, allowing you to hit all the turns with ease. A unique design minimizes the 35mm clamping area and quickly changes to a flattened oval shape in the transition zone, then to the standard 22.2 clamps for the shifter, brakes, and grips.

By reducing arm pump and vibration while also increasing steering response, this strong and lightweight riser bar only improves your handlebar. When it comes to the ultimate upgrade for lightweight yet noticeable performance, the OneUp Components Carbon Riser Bar is the ultimate necessity.


  • A carbon fiber bar that lets you ride harder for longer
  • Flattened oval shape offers forgiveness on rough descents
  • Unique shape increases steering responsiveness
  • Enjoy reduced arm pump and fatigue during all-day rides
  • Reliable 8° backsweep and 5° upsweep for a neutral feel
  • 800mm width gives you more confidence and control
