Topeak makes loads of mini pumps, but you could hardly call the Mountain TT-G mini – it’s a monster. But it’s also one of the best mountain bike mini-pumps on the market. The length is pretty similar to the other pumps here, but the girth is way bigger, and it has a huge volume. It also features Topeak’s ‘Twin Turbo’ technology which means it pushes air on both the pull and push strokes. The cadence is slightly different to a normal pump and takes some getting used to, but it got our test tyre up to pressure in no time – it’s lightning fast. It’s also really comfortable to use, your hand is protected, and there’s plenty to get hold of. The Mountain also features a handy thumb lock and, while the valve sits slightly shallow in the head of the pump, it never slipped off. The Mountain TT-G is configurable for both Presta and Schrader valves by re-organising the internals and comes with a mounting bracket should you want to carry this beast on your bike.

The Mountain TT-G is one of the more expensive pumps on test, and the gauge is not that accurate, but this is a top quality inflator that gets the job done with greater efficiency and greater speed than anything else on test.
