I've got a Raceface post and an Element SC for two years now. Just got a Woodman seatpost QR and this thing is tightened to the point it's gonna bust on me, and the post still slips.
This has never happened with the old collar.
Bought the QR cause the bike goes in the trunk o' the car.
I'm ready to put sand in it!!!!!arrrrggg

Sounds like the clamp you got is too big. Get one that's right or shim it by cutting a one inch x three inch strip of a soda can.
