First look: Shimano’s new 12-speed Deore groupset

Shimano has released a new version of their Deore mountain bike groupset, now available in 12-speed, with technology borrowed from their higher-end XTR, XT and SLX drivetrains.
This is the type of trickle-down technology that we love. Check out our overview video:
The new Deore M-6100 has all of the top-tier XTR groups’ technologies including Hyperglide+, Dynamic Chain Engagement+ and Micro Spline, as well as Shimano’s RapidFire Plus and Shadow RD+ technology. Unless you’re looking for super lightweight shifting, this new group will have you wondering whether you need to spend any more.
At the core of the new groupset is the single chainring, 1×12 drivetrain. Using Shimano’s Micro Spline hub interface allows for the huge 10-51 range all-steel cassette, which uses Hyperglide+ shifting ramps. Along with an updated chain, this offers super smooth and rapid shifting, both up and down.
The RapidFire Plus shifter enables a two-way release for your gears. Up front, the rigid crankset’s chainring can be changed via direct mount, making for easy alterations of your setup.
Dynamic Chain Engagement+ ensures reliable chain retention, while the derailleur clutch keeps the chain secure and the profiles of the teeth on the chainring and large, teeth pulley wheels keeps noise to a minimum.
So what else has been updated? Available in either two or four piston calipers, the new Deore brakes feature levers with the same rigid construction as higher-end groupsets, resulting in improved lever feel and performance. Shimano’s Servo Wave technology has been tuned as well, resulting in quicker pad engagement and clearance.
Deore level ergonomics have never been as good – I-Spec EV mounting ensuring that you can fine-tune your shifter lever and brakes to an optimum position on your handlebars, all the while keeping your cockpit clean.
If you’re running a cable operated dropper post there’s also a thumb-operated lever which can be installed on the I-Spec EV mount, making dropping and raising the saddle a breeze.
We love the look of the new Deore and can’t wait to test its performance – what about you? Let us know what you think of the updates down in the comments section below.
