The CrankTank 4 is a lightweight and rigid high capacity hydration system that fits on nearly any triangular hardtail bike, such as MTBs, gravel bikes and road bikes, and allows you to carry up to 1.06 gallons/4 liters of water. Compared to its little sister, the CrankTank 3, the CrankTank 4 is a bit larger in size and features a more rounded design.

The CrankTank kit includes everything you need to strap it on the bike and set out on your next adventure. The standard kit comes with a top-loading clip to hold your hydration tube in place when not in use. For other clip options, take a look at our CrankTank Accessories.

Similar to frame bags, rubbing between CrankTank and frame can occur over time and we recommend installing either a pair of our CrankTank Frame Adapters or alternatively wrap the areas of contact with some protective tape, such as helicopter tape for example, to protect the frame. Frame Adapters can also help with fitting the CrankTank onto some more exotic shaped or large down and seat tubes.

We are proud to say, that our CrankTanks are hand-made right here in sunny California where we are based.

Features

The CrankTank is a great companion for bike touring, bikepacking, ultra distance racing and when riding on hot days or in remote areas. Utilizing two simple Velcro straps, installation/removal takes less than a minute and thanks to the CrankTank's ideal placement above the bottom bracket, the point of gravity is kept low and bike handling is not affected.

Compared to a full frame bag, there is no leg rub as the CrankTank keeps its shape, even when completely full, water levels are visible at all times (applies to all available colors) and thanks to its sturdy design, accidentally pinching your water bladder is not something you will have to worry about.

Due to the efficient use of space and its single chamber design, the CrankTank also offers the potential for weight savings compared to mounting bottles and cages in multiple places across the bike to achieve the same capacity.
