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.
A bolted option or dropper are not options.
