I'm using the velo orange 63mm ones over 2.2'' race kings. They're supposed to fit up to 55mm but... Don't.
Had to do all sorts of things to get them to fit, stays aren't really long enough etc. You might be okay with 2.1s, I think I'd just use the 65mm bluemels next time
Edit: I should say I'm using the mk3 fork with a mk2 frame, I don't know if the shape of other forks is different?
