Yes matey that is the size of  os seat clamps. The seatposts are 22 mm and obviousley the seatpost tube has to be wider to accept it. So the clamp size equates to 25.4.  :daumenhoch:
These have it stamped on them aswell.

 28.6 would be for most new school frames that take a  standard sized 25.4mm post.

U.S size, my rampar is that size but the pinch clamp is built in to the seat post tube so uses no clamp. i think they fit a 13/16 post...

The larger clamp is as JT Racing says, for frames like the Raleigh Burner with a 1 1/8" oversized seat post  :daumenhoch:


Better to crash and burn than fade away
