Hey :wink:
I'm after a quick release for my seatpost but can't work out what size I need, existing one is a Bonty and doesn't say :( The seatpost size is 31.6 and it's a Trek 6700 if that helps.

    Measure the the diameter across the top of the seatpost tube (outer edges) Probably something like 34.9mm.

    should also be the same size as your front mech band.
