The most secure pump fastener available, the Bikeblock is shockproof, and won’t release a pump when jolted like less secure holders. Adjustable strap holds a wide variety of other accessories to chromoly frames, seat posts, and handlebars. Each channel opens separately, so the Bikeblock stays on the bike when the accessory is in use, and can also easily be removed with the pump.
