In bike size

Maybe I should have stuck with my coke can seal, but I liked the lip on this seal to keep it from falling into the seat tube. Be sure to place the spacer close to the desired location on the seat post, and then insert the seat post with the spacer into the seat tube. Otherwise the seal will move enough to roll off the edge.
