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 releases its latest 12-speed MTB groupset, the SHIMANO DEORE M6100 series, alongside new 11-speed SHIMANO DEORE M5100 and 10-speed SHIMANO DEORE M4100 versions to bring premium technologies to a new price level.
The M6100 series is molded from the same DNA the top tier XTR, SHIMANO DEORE XT and SLX mountain biking groupsets and is fully compatible with its more progressive companions so you can pick your favorite setup to match your riding needs.
Meanwhile the 11-speed and 10-speed versions build on SHIMANO DEORE’s mountain biking legacy, retaining technologies such as HG HYPERGLIDE shifting, 2-WAY RELEASE levers, SHIMANO SHADOW RD+ derailleurs and I-SPEC EV handlebar controls to broaden the versatility of this value-focused group.
SHIMANO DEORE M6100 series (12-speed)
Shimano’s proven 12-speed technologies are inherent in every component at SHIMANO DEORE level.
1x12 Crankset: The SHIMANO DEORE 12-speed crankset (FC-M6100) with its sleek metallic colour shift design comes in single-only (1x12) configuration for drivetrain simplicity. It features the same DYNAMIC CHAIN ENGAGEMENT+ technology as XTR, SHIMANO DEORE XT and SLX cranksets which, with its narrow/wide tooth profile, provides the key to the improved chain retention, smoothness and quietness of the drivetrain. For secure and fast mounting of the chainring the crank is equipped with a direct mount system, making chainring changes a breeze.
Cassette & chain: The SHIMANO DEORE 12-speed MICROSPLINE cassette (CS-M6100) is made from 12 durable steel sprockets and comes in a 10-51T gear ratio. Complete with the unmatched shifting quality of HYPERGLIDE+ technology you can shift both up and down this cassette under load, making SHIMANO DEORE shifting smoother than ever before.
The SHIMANO DEORE 12-speed HG chain (CN-M6100) offers a smooth transmission with strong chain retention by extended portions on the end of inner chain plates to combine perfectly with DYNAMIC CHAIN ENGAGEMENT+ front chainrings and HYPERGLIDE+ cassettes to let you pedal continuously, even whilst changing gear under load.
Rear derailleur: The 12-speed SHIMANO DEORE rear derailleur (RD-M6100-SGS) enables precise and quick shifting within the 10-51T range. 13-tooth pulley wheels and SHIMANO SHADOW RD+ technology reduces chain chatter and gives you improved chain retention thanks to a stiffer derailleur arm and higher chain tension.
