The aptly named Plan B is a compact and robust saddle bag. This discreet unit mounts under the saddle and around the rails using a 25mm strap with a clever magnetic hook to secure it. The YKK AquaGuard zip and 900D nylon construction makes the Plan B water resistant, the 70D Ripstop liner backs this up. There are 2 HD elastic loops inside for stowing a multi tool and a CO2 canister leaving plenty of room for a spare tube and tyre levers. When fully expanded the Plan B can accommodate a 29er tube and tools should you need to.
