NEW! Chose either Top Loading Tube Keeper re-designed for greater holding power while still maintaining ease of access or Side Loading Tube Keeper for even more holding power.  (See gallery for images of the two styles.)

Cranktank4 now available in TRANSLUCENT GREY or TRANSLUCENT WHITE (Water level is externally visible in both versions) 

Now shipping with cranked outlet cap to provide better frame bag clearance. (Straight outlet will still be available on request.)

Cranktank4 is a different and very easy, simple way to carry and access a larger quantity of water on your bike.

Conceived with the more remote traveller in mind, we have come to realise that it is also a great piece of kit to have even when just heading off on a big day out. No more detours to find water.

When designing the Cranktank4, we had these objectives.

  • Enough capacity for 24 hours in mild conditions (or all day when hot) so 4 litres
  • Easy and safe access for drinking while on the move
  • Space efficiency
  • Minimal impact on handling when full, so positioned low and central on the bike
  • Securely mounted but still quick and easy to remove
  • Robust and lightweight
  • Able to fit as many conventional double triangle frames as possible

We reckon we did what we set out to do.
