My wife’s bike has the screws for the stays in completely useless places… made it impossible to mount a rack. Took me a while to find this but it was the missing link. If you are wondering you need 31.8 size if seat post is around 27mm. Worked like a charm and quality part. Also want to say that shipping was super fast A+.
My wife and I added rear racks to our Cannondale Adventures. Hers being a small frame step thru style caused the rack to interfere with the seat clamp's quick release. This clamp solved the problem perfectly! This was the only solution I could find after hours of internet research, and this was the only store that carried it. Thanks so much!
