I'm a school teacher and I've got a team of kids building a racing car using an alfine hub as a gear box.
They used a shimano disc rotor adapter (SM-RTAD10), but need to properly do up the lockring on it. Anyone have the TL-LR10 tool (or the non-brand equivalent of it) that we could borrow? Looks like a cassette tool, but larger diameter and larger splines.
Many thanks in advance
