P Knuckle
The P Knuckle houses a wrap spring clutch and is the point that the cage is mounted to the derailleur. If you’ve serviced your clutch a few times and it’s now ready for a refresh then this is the part to change. The P Knuckle includes:
- Nylon P Knuckle housing with pivot pins
- Pre-installed wrap spring clutch
- Cage screw for re-mounting a Short or Long cage
