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.
