All Cranktank Kits will now come with the FRAME BAG STYLE cap aligned for improved frame bag clearance. The alternative STANDARD STYLE cap available by request. (See product gallery for images.)

Chose either Top Loading Tube Keeper (secure and easy to use) 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 TRANS WHITE/FLECK (Water level is externally visible in both versions) 

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.

CARBON FRAME? Consider using the Wedgie Mount to eliminate direct contact.
