Salsa Split Pivot Dropout Tool Top Cap Black with Black Bolt
$13.99
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.

- For all Salsa Split Pivot suspension models
- Integrated 22mm socket design interfaces axle nut to field change the derailleur hanger
- Operated via 6mm hex key found on most mini tools
- Takes place of standard top cap
