The Crank Brothers TS2 Tube Stash mounts to any standard bottle cage bosses and gives you a dedicated spot for a spare tube, plus the tools to fix a flat when you're miles from the trailhead. The bracket uses a hook-and-loop strap to secure a tube, lightweight jacket, or snacks. Behind that storage space sits a full-size tire lever with an integrated tubeless plug tool and two spare plugs tucked into the back. Everything you need for a trailside repair lives in one compact package that doesn't eat up frame bag real estate or take up space in your pockets.

The tire lever is stiff enough to handle tight tubeless beads without flexing, and the integrated plug tool lets you repair punctures without carrying a separate tool. Two plugs come installed in the back of the lever, so you have spares on hand when you need them. The fork on the plug tool grabs the stem of the plug and pushes it through the puncture from the inside of the tire. If you've used other tubeless repair systems, this one works the same way. The 64mm mounting spacing means it fits most modern mountain bike frames, and the low-profile design keeps it tucked out of the way when you're riding.

The storage strap holds a 29-inch tube without issue, and you can cinch it down tight enough that nothing rattles or shifts when you're descending rough trails. If you're running a tube in the rear as a backup for your tubeless setup, this keeps it accessible without stuffing it into a frame bag where it might be hard to reach. The bracket weighs 53 grams total, so it's not adding much to your bike's overall weight. Crank Brothers backs it with a five-year warranty, and replacement plug refill kits are available separately when you use up the included spares.
