e*thirteen TRS Plus Cassette Upgrade Kit with Cassette, Chain, Shifter and Derailleur Conversion Kit

The e*Thirteen TRS Plus 12-Speed Upgrade Kit lets you upgrade your existing 11-speed SRAM drivetrain to a 12-speed drivetrain without needing new cranks, chainrings, shifters, or derailleurs. All parts and required tools are included including new internals for the SRAM shifter.

• Kit is also compatible with Shimano XTR, XT, and SLX 12-speed drivetrains when used with Shimano 12-speed derailleurs and shifters
• Smaller 9-46T cassette gives a better chainline, for longer-lasting drivetrains
• The assembly utilizes XD™ Driver mounting to enable a 9-46T 12-speed cassette, keeping the drivetrain simple, yet providing the gear range of a 2X system
