Race Face is relentlessly focused on quality, and the SIXC 35 35mm Rise Handlebar has the highest rise available for aggressive downhill riders. Using unidirectional carbon fiber, Race Face was able to meet its high standards for durability without weighing you down. A larger bar and stem clamp area diameter made the handlebar as strong as it is wide. This allowed engineers to shave off even more weight without weakening the SIXC, making it lighter and stronger than the 31. 8mm version.
