Our fattest version in the RaceRocket® series this all aluminum mountain pump gets big volume tires up to pressure fast. This elegant little mini pump features a full aluminum body, head and pump handle and is designed with an increased barrel diameter to push more air per stroke. An extendable hose with SmartHead® ThreadLock fills Presta and Schrader valves with ease and helps take stress off the valve stem when filling the tire. Its efficient and smooth action inflates tires to 90 psi / 6 bar. Compact in size it easily fits in a jersey pocket or saddle bag and with a low weight of only 114 g the RaceRocket® MT is never a burden to carry into the backwoods. Note : Use the PCT Cap to tighten or remove two piece Presta valve cores when necessary.
