Deore M5100 and M6100

Deore M5100 - 11 Speed

Shimano's Deore 11-speed components have seen some fairly major upgrades with the release of the M6100 series. One of the most notable is the new 11-speed 11-51T wide range cassette. Using this cassette, the 11-speed drivetrain is now offered in a wide range 1 x 11 setup. Although this cassette still uses the standard HG freehub body, it may be appealing to those we haven't upgraded to a new standard such as Shimano's micro spline freeride hub. The rear derailleur has also been completely re-designed, offering consistent shifting performance over rough terrain.

Bringing a massive 510% gear range in a more affordable package, the new 12-speed Deore consists of a new chain, cassette, derailleur, shifter, crankset, and brakes.

Our Take

At the end of the day if you are looking for solid and reliable components, but don't want to break the bank, then the M5100 and M6100 series are a great fit for you. For 11-speed and 12-speed drivetrain setups, the budget friendly Deore is going to be the best bang for you buck, all while maintaining strong performance. By comparison, besides getting a Micro Spline compatible rear wheel, the complete Deore 12-speed drivetrain comes in at around $380CAD, which is close to the same price as an XTR 12-speed rear derailleur.
