ProTaper Trail Stem

This stem is designed for handlebars with a 35.0 mm clamp diameter. Please check your current handlebar specifications to ensure compatibility, as this is a standard size for modern aggressive trail bikes but will not fit older 31.8 mm bars.

The 40 mm length is considered short, which typically results in quicker, more responsive steering. It is an excellent choice for technical trail riding where you need snappy handling and a slightly more upright, confident body position.

Yes, this stem is compatible with a standard 28.6 mm (1 1/8 inch) steerer tube, which is the industry standard for almost all modern mountain bike forks.

A 0-degree angle provides a neutral rise, meaning it neither lifts nor drops your handlebar height significantly. This keeps your cockpit setup straightforward and is ideal if you are happy with your current bar height and just want to improve steering stiffness.

While it is optimized for trail riding, the aluminum construction is built to be stiff and robust. It is designed to handle the rigors of technical terrain, though riders pushing into heavy-duty downhill racing might prefer a dedicated gravity-specific stem.
