1×12 MTB Drives Get Cheaper: Shimano Launches New Deore Group

Shimano claims its new M6100 component set within the Deore family provides a high-quality 12-speed option ‘at the most attainable price point out there.’

Just 2 years after Shimano first launched a 1×12 drivetrain in its elite-level XTR groupset, the Japanese company today announced the tech had made its way into a more budget-friendly option.

The new M6100 group now joins the Deore family, the brand’s “beginnermediate” mountain bike component set. This means entry-level mountain bikers will have more OEM-specced bikes to choose from in lower-tier price points, and it will provide intermediate riders a similarly cost-conscious option for upgrading the bike they already have.

Shimano also announced 11- and 10-speed options that will complement the M6100 within the Deore family. The M5100 updates the rear derailleur to accommodate 11-speed shifting on electric bikes, and the M4100 improves the existing 10-speed platform with a 40% price reduction, according to Shimano.

The big news, however, is that by hitting Deore-level components, 12-speed mountain biking is poised to provide riders of all levels a better riding experience. Almost unanimously, anyone who’s ridden 1×12 prefers that setup.

According to the brand, this Deore line now has “all of Shimano’s top 12-speed technological innovations first introduced with XTR M9100.”

The M6100 drivetrain has a 10-51-tooth cassette, offering up a 510% gear range. That’s enough to bomb descents and crush nasty climbs. In all, the entire M6100 line includes rear derailleur, crankset, shifter, cassette, chain, and two- and four-piston disc brake options.

The high-end SRAM Eagle lineup confirms what we've thought for years: The 1x drivetrain is the future of mountain biking. Read more…

This is all moot for those shopping for complete bikes already specced with M6100. But for those looking to upgrade and purchase the groupset itself, the full M6100 group with four-piston disc brakes costs just shy of $600. Or for half that, $300, you can get the M6100 drivetrain by itself.

We look forward to getting our hands — and pedals — on the new Deore M6100 to see if it really offers up high fun for the low price.
