Whether we're outfitting a demo fleet or are just tired of getting the allen key out to adjust our seatpost, the Chromag QR Seatpost Clamp does the job. This QR clamp replaces the stock clamp and makes it easy to adjust our saddle height on the fly. We don't need to bring our allen keys with us while we're riding and it's easy to let friends hop on the bike if we want, or drop our saddles the old school way before a big descent.
