Press Release: Fourth-tier Shimano MTB groupset brings proven 12-speed drivetrain and braking technology to the masses, with new 11 and 10-speed versions too.


Shimano has just announced their latest iterations of their Deore Groupset, with new 10, 11 and 12-speed versions added to their lineup. As per the usual case, the M6100 12-speed version features trickle-down technology from Shimano’s XTR, XT and SLX groupsets and will, of course, will come in cheaper than any of their other 12-speed offerings.


We’ll have a groupset to test soon, but in the meantime, keep reading to learn more about their new M6100 12-speed offering.


Crankset: The Deore 12-speed crankset will only come in a single-chainring configuration. Do you really need more than one chainring with 12-speed, anyway? It features the same narrow/wide tooth profile as the XTR, XT and SLX cranksets , so chain retention won’t be an issue and the chainrings are direct-mount, so you can swap sizes to your heart’s content. Available in 170mm or 175mm, with a 30T or 32T chainring and, in three different Q-Factors.


Rear derailleur:The 12-speed Deore rear derailleur will move your chain across the 10-51T cassette quickly and accurately. As you’d expect, the Shadow RD+ technology will help chain chatter to a minimum, and keep the chances of dropping your chain low.


Shifter:The Deore 12-speed shifter features I-SPEC EV mounting, give you a ton of flexibility to get your shifter in the perfect position, along with Rapid Fire Plus and a 2-Way Release, so you can move through your gears quickly.


Brakes:The Deore M6100 brakes come in a two pistion XC variant, or a four piston trail/enduro version. Both feature a redesigned lever, adding stiffness for better feedback as well as more power and as you’d expect, feature Shimano’s Servo Wave tech, meaning the pads engage quicker, more power and a shorter free-stroke.
