The Crank Brothers BC2 combines a side-loading bottle cage with tubeless repair tools in a single unit that weighs 73 grams. The cage reverses to accommodate left or right side bottle access depending on your frame layout and which hand you prefer to use. A full-size tire lever integrates into the base of the cage, and a tubeless plug tool with two spare plugs stores in the back of the lever. The entire assembly mounts to standard 64mm bottle cage bosses, so it works on most modern mountain bike frames.

The side-loading design means you can grab your bottle from the side rather than pulling it straight up, which works better when you have frame bags or other gear mounted near your bottle cage. You flip the cage during installation to set up left or right side access regardless of where the mounting bolts sit on your frame. The tire lever has enough stiffness to handle tight tubeless beads without flexing, and the composite construction holds up to regular use. Crank Brothers backs the BC2 with a five-year warranty.

The tubeless plug tool uses a fork design that grabs the stem of the plug and pushes it through from inside the tire. This is the same method most tubeless repair systems use. The two spare plugs store in slots on the back of the tire lever, so they're right there when you need them. You just pull a plug out of the storage slot, load it into the fork, and push it through the puncture. The kit measures 114mm by 62mm by 32mm when installed on the bike, which keeps the profile low enough that it stays out of the way when you're riding.... Read More
