- Which seat clamp QR has the best clamping action
Which seat clamp QR would people recommend to be relatively easy to close but give a firm clamping action?
My friend is having trouble with slippage, she is very light so it is not a weight thing. The bike is an on-one inbred with Thomson seat post, is that a known bad combination? The current QR is an Azonic one I think. I like my Salsa Flip lock so that is my starting point for a recommendation.

Flip locks are about as good as they get ime, the opposite to my experience with a Hope QR. But check your seat post / tube tolerances are close if a light rider is causing slippage since pretty much any qr should hold if done up averagely tight – it’s usually how stiff the lever is/becomes to close at a good tension that’s the problem. A steel frame and a thomson should be good, generally thomsons seem a closer fit than many posts.Posted 4 years agoSpeshpaulSubscriber
check the inside od the frame is clean and smooth. a blast of gt85 and a quick rub with some scotchbright/wet and dry should do the trick. if there are any solid lumps then your LBS should be able to ream the tube.Posted 4 years ago
Clamps- salsa, hope, etc all good. Posts- Thomson are normally about the best fitting, double its the right size.
Check the frame, get a solid clamp. she should be right.andylMember

Thus but I’d replace the GT85 with IPA.
Another vote for the salsa. Although I tent to have Hope to match other bits and they are fine. Just make sure you have a nicel prepped seat tube and post, a LITTLE bit of assembly grit paste or anti-seize (I use shimano as I know it’s carbon and aluminium safe) and don’t overtighten.Posted 4 years ago
Ah OK, I think I have spotted the issue potentially….
The On-One website lists the seatclamp size as 29.8:
but that isn’t a very common size so I suspect it has a 30.0mm on it.
Will a 30.0 Salsa do a better job or should I seek out a 29.8mm in an alternative brand?
Surprise, surprise On-One make something in the right size and a bit fliplock esque:Posted 4 years ago
