Hi
I have a 30.9 mm Rockshox Reverb that I want to fit inside a 31.6mm seat tube.
I can't make head nor tail of the sizings on various websites.
Could someone kindly give me a direct link to the exact shim required? Preferably for a shim that you know to be a reasonably good one.
Many thanks.
I use a cane creek one which works very well that size doesn't seem to have many options but there are these.

You want 30.9 in 31.6 out
Slightly cheaper [url= http://www.winstanleysbikes.co.uk/product/31366/USE_SS_309mm_Seatpost_Shims ]here[/url] and I think free delivery. Mine came very quickly from them. It does the job very well - the only slight issue is if you like to adjust the seatpost at the QR occasionally, to perhaps give an extra bit of drop for very steep sections - the shim tends to move back up with the post rather than stay in the frame. A dab of superglue or similar between the shim and the frame would probably solve it, and it's not really that much of an issue.
Thanks folks that's great!
