Massive 511% range, light weight, a fair price, and serviceable, all without a new drivetrain. Our 11 speed TRS Race cassette gets you 511% range, using your existing 11 speed drivetrain. The aluminum and steel clusters are sold separately as replacement parts.

Our industry exclusive 9t cog allows for more range without just making the big cog bigger. It also means you can run a smaller chainring than with competitor cassettes, allowing for greater ground clearance.

The largest cogs are precision machined from aluminum and attach to a SRAM XD driver body with a lockring. The remaining eight steel cogs lock into place with a chain whip.

More range, more fun, same standard… now at am impressive 287g

What's in the box: Cassette, tool, lockring, grease packet

E*Thirteen TRS Race 11 Speed Cassette (Black)
Positives: wide range, easy to install.
Negatives: inorder to achieve the light weight the larger cogs are aluminium and unfortunately not durable . Mine lasted less than 200 miles. It is possible to replace separate parts of the cassette, but it is stlll very expensive and not easily available outside the States.

E*Thirteen TRS Race 11 Speed Cassette (Black)
Got this to replace my sram gx 11-42 cassette so I can have a wider range. It certainly offers 12 speed range without the 12 speed cost. Installation was straight forward and once you put in a couple more turns on the b-screw it shifts great! I highly recommend this cassette to anyone wanting a little more range on their 1x setup.
