Ritchey Comp Stem

This stem is compatible with handlebars that have a 31.8 mm clamp diameter, which is the standard size for most modern road and mountain bike bars. Please check your current handlebar specifications before purchasing to ensure a proper fit.

The 6-degree angle is considered a neutral, versatile geometry. Depending on whether you flip the stem up or down, it allows you to fine-tune your cockpit for either a slightly more upright, comfortable position or a lower, more aerodynamic stance.

Yes, the alloy construction and four-bolt faceplate design are robust enough for various cycling disciplines, including mountain biking. It is built to handle the vibrations and stresses of daily riding on mixed terrain.

You will need a standard set of hex keys (Allen wrenches) to secure the four-bolt faceplate and the steerer tube clamp. A torque wrench is highly recommended to ensure you tighten the bolts to the manufacturer's specifications, preventing damage to your handlebars or steerer tube.

The four-bolt design distributes clamping force more evenly across the handlebar surface compared to two-bolt systems. This reduces stress points on the bar, which is particularly important if you are using lightweight aluminum or carbon fiber handlebars.
