CONFIGURATION as stated is misleading
“CONFIGURATION: 28.6mm seat post clamp applies to 25.4mm seat post.”FALSE – This clamp is to big for a 25.4 post. Do not waste your money if your looking for a small size clamp. However in all fairness where a larger clamp is needed, it is very will made and should work fine,

The size listed IS NOT the inside diameter of the clamp.
Good luck getting the right size.Seller: there is difference between:1) the outside diameter of the seat tube.2) the inside diameter of the clamp.3) the seat post diameter.3) DOES NOT MATTER.

Not for 25.4mm post
With the quick release clamp loose it measures 28.6 and all the way tight it measures over 26.5mm so maybe if the seat post is 25.4mm it would work but this is NOT for a 25.4mm seat tube on the frame

Fit a kids bike seat post perfectly!
Replaced the hex key for a 20 inch Specialized RipRock for this adjustable seat post clamp. It does great when you expect your kids to grow a lot over the next few years.

Inner Diameter is 26.9mm
Dropping a pic in here of just how far off the inner is; really won’t fit majority of the Survivor BMX rides.My Pic shows it really cranked down (26.9mm), so not even remotely close to what is advertised.
