Road Runner's Jumbo Jammer bag is just that, JUMBO. Its a big ol' roll top bag that can collapse slightly to seem a bit smaller when not packed full of stuff. This is the largest bag in their "Jammer" line.
It has a plastic insert, like other bags, that keeps it from collapsing around your headtube or seat stays depending on where you have it mounted. This bag has a large roll top compartment to stuff a bunch of stuff into, with a single flap two pocket enclosure on the front to stuff a bunch more stuff into. The flap over the two pockets features a reflective strip and a loop to attach your blinkey light to. The bag also comes with two cinch straps to attach to the loops in the front and rear of the roll top when closed so you can really compact the bag to minimize sway or sag when loaded up.
This is a great bag for anything from your commuter bike to a touring bike, or even that mountain bike you want to go just a bit farther out on and need to bring a decent amount of stuff.
This bag is pictured in our widest 660mm Towel Rack bar.
