Someone already built your dream trail bike: it's the Diamondback Mission 4. Pairing Diamondback's efficient Knuckle Box rear linkage with proven Fox shocks makes for a plush 6-inch travel rig. Whether riding up the trail or screaming down it, the Mission turns once-unrideable terrain into your new playground. It rolls on a set of tasty Mavic wheels and sports a SRAM drivetrain with TruVativ's amazing HammerSchmidt internally geared crankset for flawless shifting and unparalleled clearance out on the trail. Plus, this sweet ride is spec'd with trick Easton carbon and aluminum components and grippy WTB tires for maximum control.
