The Topeak Roadie TT Mini Bike Pump is a precision-engineered pocket-sized pump that packs fast inflation power into an ultra-light aluminum body. Its innovative Twin Turbo system transfers larger air volumes from an outer chamber into a smaller inner chamber, dramatically reducing effort and time to reach 160 PSI (11 bar). Built entirely from metal for strength and longevity, the Roadie TT features a thumb-lock lever for an air-tight seal and an integrated dust cap to keep the pump head clean between rides. It includes a side-mount bracket for secure frame attachment and is compact enough to fit in a jersey pocket for on-the-go use.
