Race Face Turbine R Stem

This stem is designed specifically for handlebars with a 35mm clamp diameter. If your current bars are 31.8mm, they will not fit without a shim, which is generally not recommended for aggressive riding.

A 0-degree rise keeps your handlebar height neutral relative to the stem's extension. It is ideal for modern, aggressive bike geometries where you want to maintain a lower, more planted front end for better control on steep climbs and descents.

Yes, the Turbine R is engineered for aggressive all-mountain and enduro riding. Its CNC-machined construction provides the necessary stiffness and durability to handle the high-impact forces typical of technical trails.

The TopLock design uses a specific tightening sequence that secures the top bolts first. This creates a consistent, gap-free fit that makes centering your handlebars and achieving the correct torque much simpler than traditional four-bolt designs.

Yes, this stem is compatible with standard 1-1/8-inch steerer tubes found on the vast majority of modern mountain bike forks.
