Shimano Deore CS-M6100 12-speed Cassette

Cassette for Shimano's new super-wide-range 1x12 systems. Compatible only with Microspline-type cassette bodies (aka freehubs) because of the 10-tooth small cog.

• Pretty light
• Shifts well, Shimano knows their stuff
• Use with a 12-speed chain, ideally like the CN-M6100 (though we suspect other brands' work too)
• Microspline hubs only
• 10-51 tooth cogs
