With the 1x12-speed DEORE crankset you get the same DYNAMIC CHAIN ENGAGEMENT+ technology as on the XTR, DEORE XT and SLX cranks, which guarantees both the chain retention on the chainring and smooth, quiet pedalling.
The DEORE 12-speed MICROSPLINE cassette with a gradation of 10-51 teeth takes shifting to a whole new level. The unique HYPERGLIDE+ technology allows you to shift quickly and reliably at any time, no matter whether you shift to one of the 12 larger or smaller stainless steel sprockets.
12-speed Rear Derailleur
Crisp and precise shifting is guaranteed with the DEORE 12-speed rear derailleur. In addition, SHIMANO SHADOW RD+ technology optimises the chain's grip on sprockets and chainrings, which means the chain slaps less and your drivetrain makes much less noise.
RAPIDFIRE PLUS and TWO-WAY RELEASE guarantee precise, fast and comfortable gear changes on the new 12-speed shifter. As with XTR, DEORE XT and SLX, I-Spec EV allows you even more individualisation around the shifter and brake levers.
