I bought this to sit ON TOP of my seat collar - not to use as a seat collar, FYI. But it is exactly what I needed...my bike actually has rear rack mounts built in, but it's a carbon frame and I didn't trust those bolts. So I bought this to use instead, and mounted it on top of my seat collar and it's rock solid. The sizing is a little hard to figure out, though, so be aware. I bought one size larger than my 27.2mm seat post and it barely fit. Had to tweak it open and squeeze it on but it worked fine.

Easy to install, both the clamp itself and attaching a rack to it. Electra bike, electra rack, local shop was out of stock for the required clamp with rack attachment points. This did the job very well.

It’s tricky buying a piece like this because although the seat post fit ok, it didn’t sit on the frame tube properly, too small. So I kept the old seat post piece and put this above it, tightened it up , and attached the rack to it. I went to Home Depot to get screws for it, 1” were fine.

I bought a bike frame with no rack mount holes in the upper frame so I bought one of these. The two things it's supposed to do - it does very well. It holds my seat post in place and provided a perfect place to attach my Topeak Rack.
