Securely mounting to top tube bolt bosses, the Revelate Designs Mag-Tank Bolt-On bag stays put even on rough terrain. A contoured top flap with magnetic buckle offers easy one-handed access to snacks.

  • Features

    • Contoured top flap is held in place by a magnetic buckle with mechanical engagement—no zippers—for quick access to snacks, keys and other supplies
    • Easily opens one-handed while riding by pulling outward on the cord loop
    • Cover material is designed to shed rain and spray, but due to the large panel opening, it is not a sealed or waterproof bag
    • Flap-style opening means small objects can come out of the bag from rough trails or laying the bike on its side; keep loose items like keys or gummy bears in ziplock bags
    • Features 2 sets of mounting holes on bag bottom, spaced at 76mm and 100mm (+/- 2mm) off center from head tube
    • 64mm distance between mounting holes is equal to standard water bottle cage spacing
    • Interior is lined with yellow and red fabric for greater visibility; a hook-and-loop-secured, padded insert conceals mounting bolts
    • Side panels stiffened with HDPE plastic sheets
    • Adjustable-height daisy chain front attachment has a spacer block to clear stem clamp bolts
    • Tapers down to 2.5 in. tall and 1.5 in. wide
    • Mounting bolts not included
