Component maker e*thirteen rolled out the wide range TRS Race cassette last year. As gears continue to grow, e*thirteen is introducing a new version of the TRS Plus cassette with the same massive range as the Race version in a more affordable package.
This new 11-speed cassette boasts an impressive range that makes it a contender with SRAM’s 12-speed Eagle drivetrains, but at a more reasonable price-point.

How it stacks up
E*thirteen still holds the high ground in the current range wars, with an impressive 511 percent range for the 11-speed TRS Plus and Race cassettes. The tooth count for these cassettes is 9-10-12-14-17-20-24-28-33-39-46t.
The company is hoping that the combination of range, weight and price will lure customers from SRAM and Shimano.
- e*thirteen TRS Plus and Race cassettes: 511%
- SRAM 1x12 Eagle: 500%
- OneUp Shark 10-50 11-speed cassette upgrade: 500%
- Wolf Tooth 49t GC cog for SRAM and Shimano 11-speed cassettes: 445%
- SRAM 1x11 drivetrains: 420%
- Shimano 11-46t XT cassette: 418%
We measured the actual weight for the TRS Race cassette with lockring at 300g. The actual weight for the new TRS+ cassette is 339g. This puts it at 13g lighter than SRAM’s top-end 12-speed XX1 Eagle cassette and 106g lighter than Shimano’s 11-speed XT 11-46t cassette.
It’s more affordable than SRAM’s top XX1 and XO1 Eagle cassettes, but more expensive than a GX Eagle unit. Though the switch to 12-speed also requires a new shifter and rear derailleur, which makes the TRS Plus cassette look more appealing.
Shimano’s wide-range 11-speed SLX and XT cassettes undercut the TRS Plus cogset significantly, albeit with less total range.
Installation and removal of e*thirteen’s cassettes requires a few more steps than SRAM or Shimano cassettes. To install the TRS+ cassette, the three largest cogs are placed on the driver body and the lock ring is then threaded onto the freehub to hold it in place. Then, with the help of a chain whip, the eight-cog cluster locks onto the larger cogs through a series of locking slots.
In terms of shift performance, the TRS Plus cassette is consistent, but not quite on par with SRAM or Shimano’s offerings. Shift action to a larger cog is a bit slower. When moving the chain into a smaller cog the action doesn’t feel as refined as Shimano in most, but not all gears.
The shift from the TRS Plus’ 39 to 46-tooth cog and back is a smoother transition than the larger, somewhat clunky, jump between Shimano’s 37 to 46-tooth cogs.
The gap between gears on e*thirteen’s wide-range cassettes does seem more thoughtful than Shimano’s 11-46t cassette. How much this matters may be dependent on your local terrain.
Time will tell how the TRS Plus holds up to long-term testing.
