  • Is there a seat post clamp size between 31.6 and 34.9?

    I’ve got a 2007 p1 frame which uses a 30.9 seat post.

    I’ve tried a 31.6 mm clamp and it doesn’t fit on the frame, while a 34.9 clamp seems too loose.

    Apart from cutting up a coke can and making a DIY shim, is there anyway I can get the right sized clamp?

    My calipers say 33.6mm, so the closer to this the better.

    Thanks

    My Pipedream Skookum uses a 33mm clamp.

    I run a KCNC one from Clee cycles.

    Stu @ Pipedream has a stock of 33mm clamps in both qr and bolt up.

    That said Ragley make/made a specific shim to take a 34.9mm clamp down to 33mm.

    Thanks, a 33mm may be a touch on the small side.

    I’ve found a coke can now, and am gonna have a go at making a shim. :s
