The FSA Comet Stem is a dependable cockpit upgrade designed for modern mountain bikes using oversized 35mm handlebars. Built using a 3D forged and CNC machined aluminum body, the Comet stem balances strength, durability, and clean styling for riders who want reliable performance without unnecessary weight. The short 35mm length is ideal for modern trail and enduro bike geometry, helping riders maintain stable steering and confident control on technical terrain. A four-bolt faceplate evenly distributes clamping force across the handlebar while chromoly hardware adds long-term durability. This stem is designed to work with standard 1-1/8" threadless steerer tubes and can be installed in either orientation to achieve a +6° or −6° angle depending on rider preference.
