The XTR FC-M985 is Shimano's first-ever off-road, double-ring crank. Built to reward those who ride with a sense of urgency, the XTR Race M985 double-ring crank complements race-day performance with a narrow Q-factor, unparalleled power transfer, and carefully calculated CloseStep gear combinations to match riders' individual style, terrain, and horsepower. With 38-, 40-, and 42-tooth Primary Driving Gear choices--not to mention an optional, Herculean 44-tooth ring intended for pros only--the only factor limiting how fast you can go is how much power you can produce. And despite weighing in at under 700 grams, this purpose-built race crank maintains all the pipe billet steel-axle strength and cold-forged Duraluminum durability that XTR cranks are famous for.About Shimano Dyna Sys Drivetrains:
Shimano has been making mountain bike drivetrains for more than three decades, including, eight generations of Shimano Deore XT--the original off-road drivetrain--and--six generations of its flagship XTR group. Each generation is a reflection of the riding that defines the sport and the technology that defines the era. True to this legacy, Shimano's next-generation Dyna-Sys drivetrain brings with it the legendary quality, durability, and performance Shimano is known for, all packaged to meet the ever-evolving demands of today's riders. Through Dynamic Systems Engineering, Dyna-Sys brings together the rider, the bike and the trail. Intuitive gear combinations account for how riders deliver power through the drivetrain; optimization around the 32-tooth Primary Driving Gear lets riders get the most out of modern suspension designs, and even the roughest, rockiest, muddiest trails can't shake Shimano's most stable off-road drivetrain to date. Dyna-Sys is more than another batch of iterative improvements--it is a comprehensive redesign made up of a multitude of thoughtful details, features, and revisions that together add up to more than the sum of their parts.
