Just started using my 08 P7 again and the seatpost keeps slipping. What clamps are you P7 owners using?

Cheers.

On my 2007 P7 it came with a 27.2mm seatpost with a shim in it. I'm not sure what the actual measurement of the seat tube was.

If yours is the same then maybe I'd invest in the right size post but remember to use some anti-seize and refresh it fairly often!

I'll hit it with some anti-seize tommorrow. Are you just using the QR clamp that came stock from Orange?

IIRC the seat post is 27.2mm then a shim takes it up to 29.8mm, so its a 29.8mm clamp or at the most a 30.0mm should work.

Other than that email orange at: sales@orangebikes.com.uk 😀
