On the clutch mech, there’s a little black plastic button, covering the roller bearing (inside the Type2 Roller Bearing writing). You can prize this off with a stanley knife.
This reveals a T55 socket, undo this.
this no reveals a 4mm allen socket, which houses the bearing.
Remove the top pulley, by unscrewing the 3mm pivot bolt, this reveals another 3mm allen bolt.
Put a 3mm allen key against this, and put a 4mm allen key into the 4mm socket, and undo the 4mm socket – hold onto the 3mm key as underneath is the spring which can fly out if you don’t butt up against it properly.
When you’ve undone the 4mm socket as much as you can, rock the 4mm key against it to pull out the whole 4mm socket.
Push a load of pivot grease inside the now exposed roller bearing, pop everything back together. And BOOM!
Smooth as ****. Suspension will actually work better, as it’s not binding.
Essentially the bearing has been put together with no grease, so the bearing binds. Absolutely shocking.
