My new mountain bike seat had a swing clamp for easy adjustment. However the seat keep slipping so I replaced it with this rugged little screw clamp. So far it solved the problem.

Sizing chart is all wrong. Clamp was too big for the seat post diameter. Missing hardware. But it was $6 so I guess that’s what I get.

Looks like a nice clamp. I ordered the wrong size. I just measured the seatpost and ordered that size but I actually needed and ordered now the next bigger size. This one looks good though. No doubt it would work well

Ok clamp, be very careful with bolt even if using a torque wrench, still strips

I’ve been riding my bicycle for transportation for 18 years. My current bike for 11 years. A problem I’ve always had is my seatpost and seat keep moving.I have a short leg and have adjusted everything but my seatpost with success, until now. I now have pain free and stable rides with this clamp. Would recommend to anyone!
