Choosing the Correct Version
The main buying decision is the clamp size. The 28.6 mm, 31.8 mm and 34.9 mm versions are matched to different frame seat tube diameter ranges, so measuring the frame carefully before choosing an offer helps avoid a poor fit.
Before You Decide
Check the clamp size against your frame seat tube measurement, then confirm the colour and finish you want. If you need the quick release collar for a specific frame, the fit range matters more than appearance.
