Race Face Atlas Riser Handlebar

The 31.8mm clamp diameter is a standard size for most mountain bike stems, but you should verify your current stem's specifications before purchasing. If your stem is designed for a 35mm bar, this handlebar will not fit without a shim, which is generally not recommended for gravity riding.

The 8-degree backsweep is designed to provide a natural, ergonomic wrist angle that reduces fatigue during long, aggressive descents. It helps keep your elbows out and your chest up, which is crucial for maintaining control on technical terrain.

Yes, the Atlas Riser is designed to be cut down to your preferred width. We recommend using a proper pipe cutter or a hacksaw with a guide to ensure a clean, straight edge, and always measure twice before making any cuts.

Cold-drawing the alloy aligns the grain structure of the metal, which significantly increases the material's fatigue resistance and overall strength without adding extra weight. This process ensures the handlebar can handle the repeated high-impact stresses of downhill and freeride riding.

The 4-degree upsweep works in tandem with the backsweep to create a more neutral hand position, which helps prevent your wrists from feeling strained. It provides a subtle lift that contributes to a more comfortable, upright cockpit feel, especially when navigating steep, technical sections.
