51Speedshop carbon FSM extensions are designed to be a no-compromise option for angled cockpits and mid-hand position, giving an ergonomic termination angle and height.⠀ All too often, when angulation is added to a cockpit during fits, many loved extensions lose some of their admirable qualities, and during years of fittings it became apparent that a solution was needed. Fit clients' desires for a comfortable and effective extension for angulation and mid-height led to the creation of the FSM, an extension that provides an ergonomic wrist angle and height without sacrifice.
