Manual Inflation. CO2 Inflation. Why choose? With the Mammoth CO2 mini pump you get both. With a dual ano finish, this pump is premium.

The Mammoth CO2 pushes a lot of air with a low max PSI, ideal for the larger tires that come with gravel and trail riding while remaining compact and lightweight. Pair that with the added benefit of an adaptive inflation head that threads onto CO2 cartridges when you need some extra punch, and you've got yourself a very well-rounded pump.
