CrankTank 3

The CrankTank 3 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 0.8 gallons/3 liters of water. Compared to its big sister, the CrankTank 4, the CrankTank 3 is a bit smaller in size, has a narrower Q-Factor and features an edgier design.

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 hanks to its ideal placement above the bottom bracket, the point of gravity is kept low and therefore does not negatively influence bike handling.

Compared to a full frame bag, the CrankTank keeps its shape even when completely full, avoiding leg rub, 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 multiple bottles and cages all over the bike to achieve the same capacity.
