Rated 4.1 out of 5 by 9 reviewers.
Rated 5 out of 5 by Great piece I think I'll buy another one of these; this time for seat tube. ;) I currently use it instead of headset spacer under my stem: once you grind down the inner flange it fits perfectly. This allows me to remove my stem without worrying about restoring the headset position. Since I kind of like to experiment with various stems on my bike, this little part is a lifesaver. I also like the design of the clamp: it has a steel stud where the bold screws in. It is way better than having threads in the aluminium base (stronger, less wear). 02 April 2014
Rated 5 out of 5 by Quality kit! It's a nice finishing touch. Looks well, fits fine and grips seatpost solid. 22 February 2014
Rated 5 out of 5 by Nice finish and good quality Looks good, has a nice CNC finish and works perfect. Next project-bike will get the same. Clamp force is even better than the Hope clamp I use on my other bike. Good value for money!! 18 February 2014

Rated 5 out of 5 by two words (love it) needed a new seat post clamp and this caught my eye as did a lot of other nukeproof stuff.. 13 September 2013
Rated 5 out of 5 by Forza e eleganza Molto curato nei particolari ,robusto e con peso accettabile. 04 September 2013
Rated 2 out of 5 by Nice but brass barrel is poor After fitting a dropper seat post swapped the qr to one of these. Tightened it up to recommended spec - nicely printed on the side - with a torque wrench and the threads pulled out of the barrel straight away! (no i hadn't got it cross threaded) on closer inspection the barrel is made of brass and similar to what i used to find in the end of motorcycle clutch cables and whilst it may work in that application it doesnt in this one. overall nice seat collar but be very careful when tightening up. 03 May 2012

Many frames which use a 27.2mm seatpost require a 31.8mm seatclamp; but this can depend on the specific frame.

It would be advisable to measure the outer diameter of the seat tube for an accurate measurement.
