12-Speed for All - Shimano's All-New DEORE Drivetrain and Brakes 18

New SHIMANO DEORE components deliver a new level of premium performance to the value category by bringing hallmark elite mountain bike technologies to a new price level. SHIMANO DEORE M6100 is a no-compromise component group, offering a full 510% gear range and all of Shimano’s top 12-speed technological innovations first introduced with XTR M9100. SHIMANO DEORE also builds on its legacy as a versatile, value-focused group by broadening its ranges with 10- and 11-speed options.

SHIMANO DEORE M6100 packs Shimano’s pinnacle 12-speed mountain bike technologies: wide range 10-51T cassette, HYPERGLIDE+ technology, I-SPEC EV, Direct- Mount chainrings, extended inner-link plate chain, and MICRO SPLINE FREEHUB design.

SHIMANO DEORE M6100: 12-Speed Trickle Down Technology

Delivering SHIMANO’s premium technology and shifting performance, the new SHIMANO DEORE M6100 drivetrain delivers more efficient shifting up and down the cassette with HYPERGLIDE+ technology. The MICRO SPLINE FREEHUB design delivers a durable construction that works seamlessly with the system’s new 10T small cog. Adding to SHIMANO DEORE’s performance package is Shimano’s DYNAMIC CHAIN ENGAGEMENT+ that provides stronger chain retention and smoother pedaling. All of this wrapped in a powerful package with stylish details, including color-shifting logos that change hues with light angles.

SHIMANO Series 12-Speed Hubs

Rounding out the SHIMANO DEORE 12-speed system is a value-priced hub set. The non-series MICRO SPLINE MT410 hubs deliver simple setup and reliable trail performance. The radial cartridge bearings are a first for SHIMANO, offering 12-speed hub options in 142 and 148mm O.L.D. spec at the value level.

Vital Has a DEORE Group - Test Forthcoming

A complete DEORE group showed up just before launch and we've had a chance to take a quick look. Our initial impressions make us feel like this is a solid group, ready for the trails. There is generous use of metal here, no plastic derailleur bodies or otherwise dainty feeling parts could be found. To us, the inclusion of a four-piston brake is a clue as to Shimano's intentions here and we like that.

Time will tell once we get all these goodies mounted up to our bike and start clocking the miles. In the meantime, we happened to have some XTR and XT parts at the ready, along with a scale. For fun, here are some shots of the DEORE and XTR bits lined up.

Weight is one thing and for the most part we all know where the savings are made (in case the photos didn't spell it out.) What we are excited for is getting these parts on the trail, in particular, the new brakes. Top shelf stuff is nice and all but keeping the wallet heavy feels just as good to many mountain bikers. When the entire DEORE drivetrain will run you less than just a top-shelf cassette, it warrants an honest look.

In the meantime, head to bike.shimano.com for full details, including the 1x11 lineup.
