Measuring a compact 17cm in length and built with a durable aluminium barrel, the ACID RACE MCRO CMPT pump is ideal for taking on every ride, just in case of emergency. It's small enough to pop into a bag or even a pocket, but can also be attached to the bike with its own bracket. The twist-lock head works with Presta, Schrader or Dunlop valves and it's capable of pumping any tyre up to 80psi.
