I thought I'd ask in this forum since KCNC seems like weight weenie territory.
I have had no issues previously with my Thomson Masterpiece post and slipping (Al frame bike). I just replaced a dying quick release with a KCNC quick release. Now I can't keep the post from slipping down. It seems to me like the qr is cranked down hard, I'm nervous about tightening it up any further. Any input or advice?
I've had problems with qr seatpost clamps before with thomson posts. They are manufactured just slightly small (to take frame intolerances into play) but this makes them likely to slip. The clamp I used was a salsa, so high quality and not superlight - but the slippage happened no matter what I did. The choices are to replace one or other of the post or clamp.
I have 3 thompson posts and 2 of them slip when used with a QR. Worse still is the creaking/cracking noise from the psot/bolts................annoying.

maybe u can use some carbon assembly gel, it has microbeads that help create some friction between the seattube and the seatpost. That is what i'll be using for my carbon post/alu frame
I just got a Kohosis seat post clamp, based on feedback from some other posts.... it's bolt-on (non QR).... torqued to spec, so far so good - no slipping. I had a Hope bolt-on before - slipped a lot - poor design... The Kohosis seems to be a solid piece, and it only weighed 17.5g in the 36.4mm size... :thumbsup:
(the 14.4g etched on the part is without bolt I think - obviously not with the bolt in there)
