Good value & high quality
Perfect fir for 2015 Speacilized Rock Hopper. Holds tight.

Works fine…
Just the right size to use on 30.4 seat post to keep it from slipping. I use it above the quick release clamp on the seat post frame tube for positive positioning if seat is removed and replaced.

Replaced a quick release clamp.
Quick ship. It's a clamp and it works. This secures my expensive suspension post vs a quick release clamp.

Good fit
This fit my seat post perfectly because I measured the post precisely. There is a thin lip around the inner top edge of the clamp to keep it from slipping down as its tightened - so be sure to install it with that lip on top.

Great seat post clamp
Secures the seat better and more easily than OEM.

Sizing Issues
As other reviews stated the sizing didn’t work out. I even looked up the specifications on my son’s bike to verify. Next time I will do some measuring. I’m returning this one by may try it in another size. It looks like the quality is fine but I have obviously not used it since it didn’t fit
