The items that I received did not fit my bike, even though the dimensions all said they would work and matched up

Look, I've been riding a bicycle for over 40 years, and building my own bicycles for over 30, so I know for my own self where I want to spend and where I want to save. The humble seatpost clamp is a crucial part, yes, but it's also just a ring of metal with a binder bolt and shouldn't cost a ton of money unless it's something super specialized for shaving grams. This clamp is perfectly fine for your daily rider, and probably for a lot of your other bikes too.TO ADDRESS OTHER REVIEWERS' CONCERNS: I read in some reviews that the bolt would strip. I don't know those reviewers' situations, but I used grease on the bolt threads and set my torque wrench to 8nm and mine works perfectly fine, so there you go. If you're using the correct sizes of everything, no shims, and you're not leaning on it with a breaker bar, I see no reason why the clamp or the bolt would strip. But again, I'm not you, so there you go.I hope this helps! Save a few bucks when you're into an expensive sport!

I like that this lightweight, black in color, and very well finished. It was very to replace the old clamp and fit perfectly. I think it is a good deal for the price. The old clamp bolt corroded and finally fractured, hopefully the bolt used in this one is rust resistant but I can’t determine that. Recommended!

This fits the RAD City for certain. If you want to set your saddle height and not worry about someone flipping the lever to get themselves an easy new seat, this will do it. Just fill in the screw head with hot glue or putty or something so they can't get an Allen wrench in there.

I added a dropper seat post to my older XC bike, and the quick release clamp it came with no longer seemed appropriate. This clamp fit like a glove and seems to be holding my heavy butt up with no problems.
