E*Thirteen Goes Massive With New Cassettes

Date Apr 14, 2019

It seems that the cassette range wars have heated up again, with e*thirteen releasing the latest TRS+ 11 and 12 speed units. Of note in particular is the 12-speed version, which boasts a massive 556% range. Get all the details and specs from the source after the break.

Since day one, e*thirteen’s TRS Plus Cassettes have delivered more range, more value, and less weight than their competition. Now, our TRS Plus Cassettes feature revised architecture, better shifting, and are available in multiple configurations.

New to the lineup is the TRS Plus 9-50T 12 Speed Cassette with an unmatched 556% range at only 398 grams. The TRS Plus 9-46T 11 Speed Cassette offers the same 511% range, but now uses 10 steel cogs and 1 aluminum, maximizing durability and uprating it for eBike use.

New cassette architecture no longer needs proprietary tools for installation, updated shift features deliver better shifting and long-term durability, and the two-piece design allows for individual replacement of parts as they wear.

Can’t wait to try this with new XTR. Don’t want to get a new rear hub to work with Microspline so this may be the ticket!

They DO make cassettes with smaller range. Just hadn’t heard of them before, and didn’t see them on the website, because the are called a different model than the wide range ones.

They make 9-34, 9-39 and 9-42 in 11 speed, Xd freewheel., called the XCX plus cassettes.

Anyone running a Park/DH wheel or bike, this can be a very interesting option: light weight(less unsprung mass is great) and 10% smaller COGGS means you can run 10% smaller chainring for more ground clearance. Especially if you are running a 27.5 wheel, with its lower gear inches, your chainring can start to get awful close to the rocks on the modern low BB bikes.

It’s especially  nice if, like me you swap a different  wheel and tire into your trail/enduro bike for the park. In one quick and easy wheel swap you get a taller gearing with a grippier, tougher, tire for the park, and back to a lighter faster rolling tire and lower/wider gearing for the trail rides.

stop making sense you...
I am going to try 30t x 9-46t combo on my Slash this season. similar gearing to the 32 x 10-50t i am running now but lighter, more ground clearance  and way better steps between gears.

I have been running the 9-46T 11 speed on both my bikes for two years now and they are really good. particularly like the spread of the 24, 28, 33, 39, 46 part of the cassette is really useful. 30T front for steep terrain. Shifts as well as 11 speed XO1 and better than 11-46T XT. A 13-48T 11 speed cassette with even smoother shifting due to smaller spacing would be more useful to me.

After 2500 km of single track and horrible Chilcotin lava ash grit I have replaced the upper three gear part of the cassette but the steel block is basically unworn.

I received this new version cassette yesterday and was stoked to get it installed last night.  Only downside so far is the backpedal in the 46t, it drops down the cluster with 1/2 rotation.  I'll be going out for a real ride tonight and hope that maybe it will break in and with some adjustment I can make it stop.   The Sram GX 10-42 didn't have this issue.
