There never seems to be a perfect solution for storing gear on the bike. XLAB's newest offering solves this problem flawlessly with a two-compartment container designed to keep a multi-tool, speed chuck, CO2 cartridges, a patch kit, two tire levers and a tube in a compact and noise-free package. The Gear Box Kit fits into a bottle cage, so it frees up space in your jersey (or tri kit) pockets, too.
