Shimano's thoroughbred XTR group is centered around their first-ever two-ring off-road racing crank, which comes in carefully calculated CloseStep gear combinations to match riders' individual style, terrain, and horsepower. With 38-, 40- and 42-tooth Primary Driving Gear choices-the only factor limiting how fast you can go is how much power you can produce.
