Know before you buy
This stem is designed for aggressive riding styles, including All Mountain, Freeride, and Downhill. Its robust construction is built to handle the high-impact forces of technical descents while remaining light enough for climbing.
The Atlas stem is compatible with handlebars featuring a 31.8mm clamp diameter. Please check your current handlebar specifications to ensure they match this standard.
The stack height is 40mm. This measurement is important because it dictates how much steerer tube length you need; if you are replacing a stem with a different stack height, you may need to adjust your headset spacers to maintain your current fit.
A 0-degree angle provides a neutral rise, which helps keep your cockpit height consistent. This is ideal for riders who want a stable, predictable feel in the front end without significantly altering their bar height.
The interlocking U-shaped design helps distribute clamping force more evenly across the handlebar. This secure 4-bolt setup minimizes stress points and ensures your bars stay firmly in place during aggressive riding.
