Now you can convert almost any SRAM 11-speed drivetrain to a 511% 12-speed using e*thirteen’s all new TRS Plus 12 Speed Upgrade Kit. The kit includes a 12-speed cassette, chain, and parts to upgrade your SRAM 11-speed shifter and derailleur. Here are the details and photos of each element:
TRS Plus 12 Speed Cassette
The new TRS Plus 9-46T 12-speed cassette offers a 511% range and should save weight over other 12-speed drivetrains by using a shorter chain and a smaller chainring to achieve similar gear ratios. Like the 11-speed TRSr and TRS+ cassettes, e*thirteen’s new 12-speed cassette features two clusters: a one-piece set of 10 steel cogs and an aluminum cluster with the two largest chainrings. Read the full specs below.
- Replaceable aluminum and steel clusters
- Shorter chain for weight savings vs. SRAM™ Eagle™ 12-speed
- Smaller chainring and derailleur offer more ground clearance
- 336 grams
- 9-46T cassette (9, 10, 12, 14, 16, 18, 21, 24, 28, 33, 39, 46)
- 10 steel cogs, 2 aluminum cogs
- 511% range
- Faster shifts in the bigger cogs

11-Speed Shifter Upgrade Parts
The shifter upgrade kit allows you to convert your 11-speed SRAM™ GX™, X1™, X01™, and XX1™ shifter to a 12-speed shifter. Kit includes injection molded shifter spool, one stamped steel ratchet (for SRAM™ GX™, X1™, X01™), one stamped steel ratchet (for SRAM™ XX1™), pivot bolt, washer, and shifter assembly fixture.
11-Speed Rear Derailleur Upgrade Parts
e*Thirteen includes all the necessary parts to upgrade an 11-speed SRAM™ rear derailleur to work with the e*Thirteen 12-speed cassette. The kit works with all SRAM™ 11-speed rear derailleurs (SRAM™ NX™, GX™, X1™, X01™, XX1™) and includes two derailleur pulley spacers, as well as one long and one short derailleur cage bolt.
Also included with the 12-speed Upgrade Kit is an e*thirteen 12-speed chain that weighs 268 grams and has 126 links in total. The chain is plated and lubricated for durability and precision shifting, and includes a 12-speed quick connect link.
The e*thirteen TRS Plus 12 Speed Upgrade Kit is available as of today for $299 and includes the 12-speed cassette, 12-speed chain, upgrade parts for shifter and derailleur, and all the necessary tools. Find out more over at bythehive.com.
