Carbon Fiber Bicycle Handlebar Stem 31.8mm

Ultra-light, stable and easy to install, with uniform carbon patterns and a smooth scratch-free finish. Choose length based on bike type and riding habits to reduce hand/wrist pain and back load, ideal for all riders.

It boasts 2 stylish finishes (3K Glossy/3K Matt) with uniform carbon web patterns, clean ends and an ultra-smooth, scratch-free surface. Beautiful markings assist with alignment and mounting, instantly elevating your bike's grade while ensuring durability for long-term use.

Different stem lengths offer distinct benefits: lengths <90mm provide easier, faster control, ideal for agile riding; lengths >90mm deliver better stability, perfect for high-speed cycling. The stem's length directly affects bike response-shorter stems for quick reactions, longer stems for steady high-speed rides, catering to diverse riding needs.

Designed for easy installation: connect to your original bike fork, and the four-screw clamp firmly secures the handlebar. Follow the 4Nm specified tensile torque (hex wrench recommended). Apply carbon fiber mounting paste to the handlebar during installation to ensure a firm, non-slip fit, preventing loosening during riding.

Before assembly, confirm the handlebar diameter is 31.8mm and the fork shaft tube diameter matches the stem (28.6mm/1-1/8"). Alternately tighten the fork shaft fastening screws a quarter turn at a time for even torque. Compatible with most MTB, mountain bikes and racing bikes, serving as a perfect prefabricated spare part for your bike.
