The FSA KFX Drop Stem is a purpose-built mountain bike stem for riders who want a lower, more aggressive cockpit without compromising steering precision. With a steep 20° drop and an 80mm length, it helps bring the bars down and forward to improve front-end control on steep descents and when weighting the front wheel matters most.
20° drop angle - Lowers stack height for a flatter cockpit setup and a more forward, controlled riding position
80mm length - Balanced reach that supports confident handling on modern trail and all-mountain setups
Alloy construction - Strong, trail-ready durability in a lightweight package
Precise steering feel - Designed to keep the front end stable and predictable when the terrain gets steep and fast
