To make quick and easy work of filling your mountain bike tires, use the Blackburn Chamber HV Floor Pump. This pump is designed to push more air per stroke, saving energy that you might need for riding, made possible by using a low 50 PSI/3.4 Bar max pressure. It uses a huge, four-inch gauge so it’s easy to read the pressures in both the PSI and Bar measurements to easily dial into the specific pressure you desire. It works with Presta, Schrader, and Dunlop valves, so you can swap tires without worrying about swapping pumps to inflate them. Final touches on the Blackburn Chamber HV Floor Pump include a 47-inch hose for extra-long reach, an oversized pump shaft for increased durability, an alloy cap and lever, and a conveniently placed hose keeper on the handle for clean storage.
