Just bought a new carbon frame but want to use 27.2 seatpost. Seat tube usually takes 31.6. Has anyone had experience using a shim, if so which one. Have you had any issues or creaking?
I use one that came with a TT seat post, works fine no creaks, fitted on carbon bike
I use a cane creek one. The seatpost slipped a bit for a while (carbon into alu shim) but has stabilised now.
USE shim and never had a problem with creaking ir slipping.
USE thermoplastics all round here, they are machined to avoid slippage, lather them in plastic paste and jobs a good one.
I use a USE shim to fit an Ergon 27.2 seatpost to my 31.6 seat tubed boardman. works perfectly. No creaks, no slips. Helps build in a little more comfort
Again, I used a USE thermoplastic shim on a my old Whyte 19 hardtail. Once i got the setup dialled, no problems at all and it had the effect I suspect your looking for.
+1 to the above. I have a USE shim to fit a nice & springy KCNC seatpost (30.9mm) that I got half price, into my Condor (31.6mm) & it's been flawless.
Yes, used for years on an MTB, no issues whatsover
