We took the beloved Mag-Tank™ and made a version compatible with top tube bolt bosses.
The Mag-Tank takes a new twist on top tube bike bags by doing away with a zipper! The Mag-Tank features a smartly contoured top flap secured by a magnetic buckle with mechanical engagement, ensuring no accidental openings, even when your bike is upside down. With one-handed operation, simply pull the cord loop outward for full top access; closing is a breeze with a simple flick of the flap.
The Mag Tank excels at fast on the go access to calories and electronics and now includes a TPU liner built from the same material as hydration bladders. The liner is easily detachable with velcro for post ride cleaning. No more sticky food messes after your long rides – just pure convenience and functionality.
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 fully sealed bag or waterproof bag. Additionally, while the closure is secure, there is the possibility that small objects can come out of the bag from rough trails or lying the bike on its side. A key clip is integrated into the bag, but we recommend keeping your gummy bears in a ziplock.

Mounting bolts are not included. During test fitting we have noticed that longer bolts may be needed on some bikes including the Salsa Cutthroat. Two sets of mounting holes on bag bottom to allow bolt-on attachment to top tube.
- First set of mounting holes spaced at 76 mm (+/- 2 mm) from the front of the bag
- Second set of mounting holes spaced at 100 mm (+/- 2 mm) from the front of the bag
- Distance between mounting holes is 64 mm (standard water bottle cage spacing)
