Cage Mount Adaptor


The Cage Mount Adaptor is a simple way to provide a mounting solution for all types of cages to fork legs, down tubes etc. Sure, they’ve been done before, but what is different about this ours is the V section underside which provides two lines of contact and so greater mounting stability.

The Cage Mount Adaptor uses the same robust additive manufacturing process that is used for our Cranktank4 Caps, Tube Keepers and Wedgie. In fact, two prototypes have travelled both the GDMBR and the Tour Aotearoa.

We prefer utilising stainless hose clamps to secure these to the bike but, equally, the old simple method of cable ties and self adhesive tape will do the job too.

It includes:

1 Cage Mount Adaptor
3 x 5 mm x 16 mm bolts plus washers and nuts
1 Self Adhesive Rubber Strip

(Cages not included.)



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.

Cranktank4 now available in TRANSLUCENT GREY. (Visible water level.) 

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.

  • Capacity: 4 litres (1.06 US Gallons)
  • Fitted weight: Approx. 480 grams
  • Materials: Various
  • Major components are manufactured in Australia. Some ancilliary components imported.
  • Note: Water level is externally visible for White and Grey Translucent models. The Opaque Grey requires removing cap to check water level.



I don’t know about you, but one of my dislikes while out on the bike on a hot day is drinking water from a bottle that is the temperature of a cup of tea. While it’s not exactly a fridge, the CrankTank4 Neoprene Cover provides insulating properties to keep the water cool while adding some visual appeal.

The cover fits simply over the tank and fixes securely around the seat and down tubes using hook and loop fasteners. It takes just a few seconds to fit.

All the rage grey contour pattern with Adventure Hydration logo in the top corner.



  • 4 mm printed neoprene with hook and loop fasteners
  • Weight: 145 grams.



Pack of three Silicone Bite Valves for use with most hydration tubes. Suitable for tubes with outside diameter of around 9 mm to 10 mm. These bite valves simply slip onto the tube or tap fitting.

Plain cap without fittings for use in camp or if Frametank4 is just required for carrying water and not drinking on the bike.


  • 1 Plain Cap with O ring seal.



This is the 120 cm length Insulated Tube with Bite Valve as supplied in the Frametank4 kit. It can be supplied with the standard female quick disconnect fitting as used in the Frametank4, with a male quick disconnect fitting for use with Camelbak bladders or with no quick disconnect fitting.

Available soon! Side Loading Tube for even more tube security.

These keepers are designed to be fixed to round tubes (handlebar, top tube etc) in either of two orientations.

Ideal for if you’re using CrankTank4 on a second bike or even for use with a bladder in frame bag set-up.


  • 1 3D Printed Tube Keeper
  • 1 piece Self Adhesive Rubber Strip

The Wedgie fixes to the frame using the standard two boss bottle cage mount. It provides positive location for the CrankTank4 when extra clearance is required or frame profiles restrict.

It is designed for use on the seat tube when extra clearance is required for a derailleurs or for use on down tubes for cable stop clearance or for those that utilise broad, squared off profiles as often seen with carbon or aluminium frames.


  • 1 3D Printed Nylon Wedgie
  • 2 x 5mm Stainless Bolts
  • 2 x 5 mm Stainless Washers
