THE SEAT POST EXTENDER IS MADE FOR RACERS WHEN YOU NEED TO WARM UP OR COOL DOWN AFTER A RACE, OR FOR WHEN YOU WANT A MORE COMFORTABLE SITTING POSITION WHEN CRUSIING AROUND, DUE TO THE ULTRA LOW FRAME DESIGNS AND SUPER SHORT RACE SEAT POSTS.

You just insert your current seat post & seat into the extender & ride away.
* The Insight Seat Post extender requires a 2nd seat clamp to clamp down the post into the extender.
