Revelate Designs Mag Tank


4.0 (1 review)

The Mag-Tank takes a new twist on top tube bags. Instead of a zippered opening, access to the bag is by a smartly contoured top flap held in place by a magnetic buckle with mechanical engagement (read – the magnet aids in closure, while load is placed on a connection). It will not unintentionally open and spill your gummy bears when you end up in the trees with your bike upside down like a conventional magnetic closure would. You can easily open the bag one handed by pulling outward on the cord loop and you have access to the whole top of the bag. To close, just flick the flap down and the buckle self-engages!

Compared to our standard Gas Tank, the Mag-Tank is just a hair smaller to prevent leg movement from hitting the edge of the flap opening.

Please note – while the cover to this bag is designed to shed rain and spray, due to the large panel opening it is not a sealed bag or waterproof bag.

    Very nice bag. The magnet lock works great and the content of the bag stays dry in heavy rain.
    I think the also do a bolt on version. My bike has mounts for this on the top tube and if I would buy again I would go for that.
