Had to replace my original ENVE seat post collar as the bolt broke while trying to remove the collar for service and couldn’t remove the broken bolt from the collar.
5 star because the problem was too much loctite and not the quality of the collar.

Ordered this for my Lauf Seigla. This clamp has a standard OD of 31.8mm, but the Lauf has an odd 31.2mm side. This clamp would have worked, but ended up going back to the proper 31.2mm clamp. But not to worry, this ENVE clamp will be used on another bike!
