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 and seat into the extender and ride away.
* The MCS Seat Post extender requires a 2nd seat clamp to clamp down the post into the extender.
Round seat tube sizes : 22.2mm
