Upgraded, the BMW Enduro Mountain Bike 2012 is a high-end entry with monocoque aluminum frame and full suspension. For your component checklist: 30-speed Shimano Deore XT gears and XT hydraulic disc brakes, Fox suspension, Crank Brothers wheels. And there is the striking new colourway: matt black with neon green accents! BMW has been in the bicycle business since WWII, and is an original champion of aluminum for bikes. The new Enduro drops in April, for about $4,500.
