Revelate and Gromits

We took the beloved Mag-Tank™ and made a version compatible with top tube bolt bosses.

Now with an additional set of mounting holes to fit a wider array of frames with top tube bolt bosses including Niner, Salsa Cycles, 9:Zero:7, Open, Lauf and more!

The Mag-Tank™ 2000 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!

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 nor waterproof bag.

Note: Mounting bolts not included. During test fitting we have noticed that longer bolts may be needed on the Salsa Cutthroat.

Although the closure is secure – due to the flap style opening there is the possibility that small-loose objects can come out of the bag from rough trails and lying the bike on it’s side. We recommend putting things like single keys and M&M’s in a ziplock.

    Love it

    I like the easy access and capacity to hold lots of snacks. The buckle is a little finicky as it pulls off when cinched down tight. Was running it on a cutthroat with a chuck bucket on either side. Is right but works. Revelate Designs Mag-Tank 2000 Bolt-On Revelate Designs Mag-Tank 2000 Bolt-On Review

    The little things that count

    These revelate bags are great & exactly as expected so no real surprises there but the really nice part of working with campfire was them being forthright in response to me having misplaced an email coupon, & also getting ahold of an elusive Tubus part (actually two parts..) that are rarely stocked domestically. I needed both to fine tune a rack & now it couldn’t fit any more perfectly. Was a great interaction all the way thru.
