The Salsa Split Pivot Dropout Tool Top Cap is a 22mm socket designed for in-the-field derailleur hanger replacement of Salsa suspension frames featuring Split Pivot technology. The Dropout Tool is designed to double as a top cap for a standard threadless stem/headset assembly, so that it will always be conveniently available in the event of a hanger failure. This tool is intended for trailside repairs only. Once you return back to base, use a torque wrench to achieve the proper torque spec of 18Nm. Features: Lightweight aluminum bolt Specs: S.H.I.S.
