- P7 Slipping Seat Post
Try some carbon fibre assembly gel that's designed to hold carbon parts in place without crushing them, works a treat on my seatpost, suspect it'll work on alloy posts just as well.Posted 8 years agojondMember
Ditto – I'm sure they ream them oversized. I checked the USE shim on my '03 P7 yesterday and it's cracked where it's been stressed too much to stop it slipping – I'm gonna see if I can get one the next size up to compensate. I've previously knackered a seatpost QR for the same reason – needed to be so tight that the nylon washer under the qr cam bust 🙁
FWIW, there was a similar thread a few weeks ago…
It's the only frame I've had which has been anything like as bad as this.Posted 8 years agoskaifanMember
This is a common problem with the P7. I swapped the OEM orange post on mine for a race face one, and it stopped the slipping. I now run the OEM orange post on my Cotic without any problems, so can only assume the problem is caused by the shim in the orange. Carbon assembly paste apparently does the trick too.Posted 8 years agomccann.benSubscriber
I have had this problem over the last two weeks.
I spoke to orange earlier in the week.
Common mistake is to greese the post (which I did!)
DO NOT GREASE THE POST!
If grease gets between the shim and frame you are screwed.
My LBS reccomended getting rid of the shim so have a 29.8mm Thomson on order.
Make sure you get rid of as much Grease as possible.
I wonder if this is one reason why the 2010 frames do not have a shim?Posted 8 years ago
