Our first true universal fitting frame bag, the Hopper fits most adult sized bikes and many full suspension frame bikes with a vertically mounted shock.
This mid-frame fitting zipper-less bag was painstakingly developed to work well whether the bag is empty or full to the brim. Due to a short length that would make zipper access difficult, we combined design knowledge from the popular Mag-Tank cockpit with a decade of tried and true frame bag manufacturing. The result is a single-handed accessible, panel opening frame bag with an effortless magnetic closure.
We’re now offering the Hopper bag with a hydration bundle! The hydration system includes a 1.5 liter water reservoir, HydraPak Plug n’Play hose for easy refilling, and our Barnacle handlebar clips. The Hopper does not have a dedicated hydration tube port, but running a hose out behind the flap opening works great!
The Hopper’s unique design allows for the shape to be compressed or expanded over the profile of the bag to fit a wide array of bikes. To best determine fit, you may use the sizing charts below.
