Shimano XTR M985 Race 10 Speed Double Crankset

If you expect every bit as much out of your equipment as you invest in your training, then you're in the right place. The new XTR Race group doesn't just ask to be pushed at race pace, it demands it.

Shimano's first-ever off-road double-ring crank rewards those who ride with a sense of urgency. This new thoroughbred kit is starts with Shimano's first-ever off-road two-ring race crank, which comes in carefully calculated CloseStep gear combinations to match riders' individual style, terrain, and horsepower. With 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 under 700 grams, this purpose-built race crank maintains all the pipe billet steel-axle strength and cold-forged Duraluminium durability that XTR cranks are famous for.

It all adds up to mindlessly fast shifting, and gives racers fewer excuses for losing and even more ways to win. It's not for everyone, but for those up to the challenge, XTR Race delivers like never before. The XTR Race M985 double-ring crank complements race-day performance with a narrow Q-factor, unparalleled power transfer and CloseStep chainring options to suit racers' speed and style.

Please note, external Hollowtech II Bottom Bracket is included.The race version is a bit lighter,The trail version is bit sturdier......

M985 is available only as a double: 40-28, 42-30, or 44-30, wIth a BCD of 88mm.
