The Mag-Tank FastTrack features an ultra low profile quick-release mounting system for any bike with top tube mounting bolts. It allows you to quickly strip the bag, or swap to a different bike in seconds with best-in-class stability. The bag features a stiffened internal structure and a fitted lid with welded construction. The Fidlock magnetic buckle holds the lid tight and keeps contents secure when the route gets rowdy. A removable TPU liner lets you easily clean your snack mess after your bender in the hills.
