For a sleek design, light construction and pumping ability, cyclists need only to look at the RaceRocket CB MasterBlaster. Its carbon body has an embedded Ti mesh in the handle for increased grip that weighs only 75g! Its efficient single-action design inflates mountain or road tires up to 140psi/9.6bar and features the innovative SmartHead ThreadLock. This minimal head fits Presta and Schrader valves using a flexible hose to take pressure off the valve stem when pumping. After pumping the hose retracts into the carbon pump body for a compact size that easily fits in a jersey pocket or seat bag and ready for the next race or training ride.
