Magnets, straps or a ring — and what your tank is made of · review
A waterproof 6-litre tank bag on a Quick-Lock ring mount, measuring 30 × 22 × 19 cm, with a waterproof viewing pocket in the lid and a factory-fitted guide rail for position adjustment.
The bottom line A ring mount that works on any tank material, an adjustable position, and published dimensions. It costs more than the rest of the family together.
A waterproof 6-litre bag on a Quick-Lock ring mount, 30.0 × 22.0 × 19.0 cm, with a waterproof viewing pocket in the lid for a phone or map, and a factory-fitted guide rail that lets the bag’s position on the tank be adjusted to the rider.
Two other bags in this family are magnetic, and both require a steel tank. A ring bolts to the filler cap and holds regardless of what the tank is made of. The cost is that the ring stays on the machine and has to be fitted once.
A tank bag occupies the space a rider’s chest moves into. A guide rail that shifts it forward or back is an ergonomic adjustment, and it is the difference between a bag that is used and one that is taken off after a month.
A hydrostatic head figure. “Waterproof” is stated rather than measured, where a rain suit on this same site publishes 10,000 or 15,000 mm.

A ring that fixes to the tank’s filler-cap bolts and stays there; the bag clips on and off it. It works on aluminium and plastic tanks, where a magnetic bag simply will not hold.
A tank bag sits where the rider’s chest and forearms go. Moving it a few centimetres decides whether it is in the way in a tuck, and the maker publishes a guide rail for exactly that.
Any tank a magnet will not hold, on a machine that will keep the ring fitted.
