New Products 12 Speed Cassettes
12 speed cassettes are found on current mountain, road and gravel bikes. Each manufacturer has a specific freehub body for their 12 speed cassettes. Sram uses XD freehubs for mountain and the XDR freehubs for their road and gravel ranges. Shimano has its own Micro Spline system for their 12 speed mountain range. Sram's MTB and Road systems, along with Shimano's MTB system allow the use of a 10 tooth small cog. Companies, such as SunRace, offer 12 speed cassettes which can be mounted to older Shimano 9/10 speed freehubs.
