I’ve got a new 30mm one, a size they’ve only just started doing.
I fitted it, tightened it up…..that’s it! I’ve noticed a small bit of slippage but not a lot, so undid it and tweaked the nut.
I have the older type too on another bike, the new one feels like it has a longer ‘handle’…. it feels comfortable when tightening.
….and mine’s black!!!
Ummmm that’s about it!!!
I got a 30mm last week – very nice, the lever is much nicer than the old ones but the silver tightening nut sticks out a bit compared to the old ones. Needs to be very tight to stop slippage.
Still loads better than cheap generics, Salsa’s and the OnOne cnc I had. I think the biggest plus point is the big brass push which they still have and the others don’t.
