   Hi,

   So I'm suffering with a slipping seatpost on my P7, I have the one that fits 29.6 but is shimmed to 27.2 and I have a bog standard QR clamp on it. Does anyone know of an off the shelf halway decent 29.6 seattube? I tralwed everywhere I could think of last night and came up with nothing.

   Or shall I just replace the clamp and deal with having an ugly shim in there forever?

   I know the pain you're going through!!

   1 - Ditch the crappy clamp that came with the bike

   2 - Add 50% carbon assembly gel, 50% general purpose bike grease to the seatpost (NOT the underside of the shim)wipe off the excess

   3 - Use a different clamp such as a Hope QR

   Other P7 owners have succeeded with skipping step 2 and not using any lube, I didnt, I found it still either slipped, creaked or both.

   Good luck

   EDIT - I dont know about removing the shim and putting in a bigger seatpost but if you get anywhere with this please update this thread

   I've got a 2010 P7,with no shim.The seatpost still slipped.I binned the crappy OE clamp and fitted a Hope non QR clamp. That's fixed it.

   enfht - stupid question but what size seat clamp did you buy? a 30.0mm?

   I'll be putting my retro-freak friend onto sourcing some NOS 29.6's, maybe Whiskers have something of use - I'll let you know what we find

   I've got a tidy retro (1993) black syncros 29.6mm x 425mm that I used to have in my P7, Yours for £30.00 with recorded delivery. Mail me if interested & I'll send some pictures.

   31.8

   2008 frame if that makes any difference (dont think it does)

   Hope non quick release clamp was my way forward.

   +1 for ditching the standard clamp.
   I put a 30.0 hope QR on my post after having the same trouble on a 2010 frame (no shim).
   Although it still slipped initially unless I tightened the QR heroically, it's now fine (?!) shame about how it looks - the post is a real mess after managing to slip with the original clamp tightened (beyond) fully.

   Thanks for the feedback gents - and thanks for the offer rc200f8. I think I'll try a new clamp and see how that goes.
