Blackburn Mammoth AnyValve Pump
The Blackburn Mammoth AnyValve Pump takes the guesswork out of which adapter goes where. The reason is because there are no adapters to choose from with the Blackburn AnyValve Head which automatically adjusts to fit Presta, Schrader or Dunlop. SO, it's easy to figure it out. The Mammoth weighs just 157 grams and features a rubberized folding T-handle for a solid grip and easy pumping without the extra effort, and Blackburn's lifetime warranty means it may be the last pump you ever buy.
