Shimano Deore 11s M5100 Groupset, 1x11, w/ crankset

Shimano's entirely new Deore 12s M6100 group features many of the same technologies and component standards as XTR, XT and SLX. It's a dedicated 1x12 groupset with a 10-51t cassette, but requires Shimano's Micro Spline freehub body making upgrading an existing drivetrain difficult. 

This is where Shimano's Deore 11s M5100 comes in. It also offers many of the same technologies including a 11-51T cassette, but utilized the longstanding Shimano HG freehub standard making it the perfect option for upgrading existing 8/9/10 speed drivetrains.

Confused? Drop us a line before ordering!

⚐ Your rear hub must have a HG-C body in order to accept the cassette included in this groupset.
Easiest way to confirm: if your current cassette's smallest cog has 11 teeth - you're good.
