my 2006 avalanch has a 31.8mm clamp and a 27.2mm seatpost I would imagine if your frame takes a 27.2mm post that it would also be a 31.8mm clamp take the post out it should have the size stamped on it below the minimum insertion mark also some clamps have the size stamped on them
Fig rolls: proof that god loves cyclists and that she wants us to do another lap
Took ages to find the size of mine - Specialized being what they are have their own exclusive size.
But I found it on here and have literally just fitted a lovely Hope QR clamp - for some biazarre reason Stumpjumpers come with a non QR seat clamp - are they trying to save a few grams or just being stingy?!
Two Stumpjumpers, a Rockhopper Disk and an old British Eagle.
