Are you buying a seatpost from Bikeman and need it shortened? Do you have a cutting guide, a hacksaw, cutting fluid, and a wire wheel? If not, let us do the hard part for you. Simply specify the length that you need your seatpost cut to from the bottom of the saddle rail to the bottom of the post (IN MILLIMETERS ONLY!) and we will cut it to length for you. Be careful, because whatever number you type is the length that Bikeman will cut it to, and we will not accept returns on seatposts that have been cut.
