RaceFace Atlas Stem

This stem is designed specifically for handlebars with a 35mm clamp diameter. Please verify your handlebar diameter before purchasing, as it will not fit 31.8mm bars.

The interlocking geometry distributes clamping force more evenly across the bar surface. This design eliminates stress risers, which are common weak points that can cause handlebars to bend or fail under heavy impact.

Yes, the Atlas is built to bridge that gap. It is engineered to be light enough for all-day trail riding while maintaining the structural toughness required for aggressive downhill and freeride abuse.

The RaceFace Atlas features a 40mm stack height. You should ensure your fork's steerer tube has enough length to accommodate this measurement when setting up your cockpit.

The opposing bolt design requires a specific tightening sequence to ensure the clamp is secure without adding unnecessary stress to the steerer tube. It provides a very reliable, high-strength connection, but be sure to follow the torque specifications provided in the manual.

Yes, the Atlas is compatible with carbon bars. The faceplate design is specifically intended to reduce stress points, which is crucial for maintaining the integrity of carbon components.
