With the Topeak Mountain TT Twin Turbo, you can easily inflate fat bikes, gravel bikes, and mountain bikes with high pressure and a large volume. The Twin Turbo Technology uses both pulling and pushing motion to draw in and compress air. This allows the Mountain TT to achieve a pressure of up to 8 bar and is compatible with Presta (SV), Schrader (AV), and Dunlop (DV) valves.
