e*thirteen's TRS Race 11-speed cassette, which we first spotted at this year's Eurobike trade show, is now in full production and available for purchase. The follow up act to their 9-44 tooth TRS+ cassette, the TRSr boasts a massive 511% gear range thanks to its 9-46 tooth spread. For comparison, SRAM's 12-speed Eagle drivetrain has a 500% range, and Shimano's 11-speed 11-46 cassette creates a 418% range.
There's no shortage of drivetrain expansion accessories these days, but the TRSr is certainly an intriguing option, especially since it works with existing 11-speed drivetrain components - there's no derailleur modification necessary to get it up and running.

Even with its extra-wide range, the cassette still weighs in at only 307 grams, which is lighter than both Shimano and SRAM's highest end offerings. The cassette uses a two piece design - the eight smaller cogs are constructed from steel, and the largest three are aluminum. Each piece is available separately, allowing riders to avoid shelling out the cassette's entire $349 asking price when they need to replace either their climbing or descending gears.
We're only just started to put in the miles on the TRSr - stay tuned for our final verdict once we use and abuse it over the course of a wet and muddy winter.
I think I will stick with a £60 Sunrace 10 speed cassette and push up the really big hills, or freewheel down when I run out of gears.
Having said that, i would never spend that much on one, only if i wont the loterry
I could buy an XT cassette, but then need to buy a new driver, and the cassette would have less range and be heavier anyway.
Sometimes MTB is just a kick in the nuts.
This looks like a good option for a similar price though too. I wonder how much the replacement big cogs are?
e-13 is a smaller company with a smaller overall sales revenue. It simply cannot compete at the moment with giants like Shimano and SRAM. Even though SRAM does have their own expensive ass cassettes.
I for one would love to have this cassette. The 500+% range and the added weight reduction is a plus in my book.
I run a 36T Chainring up front so I could definitely use the extra high end increase in speed with the 9 tooth cog.
Plus black cassettes are cool
511% agree with the comments.
... and so glad I still ride 9sp and SS - cost me like 11.82% of what these crazy people are asking for.
What you may think is not worth it many others will see value in.
The shifting is incredible with a Shimano chain, better than the 11-40 (with Wolf-Tooth 45T expander kit) M8000 cassette I have on another bike. It has been sloppy here in the northeast and with about 400 miles on it I am very impressed with the wear as I was a little concerned with the aluminum cogs. I also haven't experienced creaking yet but I also haven't been washing my bikes as much as I used to. With a 32t up front the range is great and the 9-tooth allows for a smaller front ring while avoiding spinout versus the Shimano 11t minimum. This certainly makes 12-speed seem a little unnecessary.
Again, I understand the issue with the price but if you want a big 1X gear spread without going 12-speed and think shaving 150-300 grams versus another setup option is worth the coin than I would recommend this cassette.
However, looking at similar sized cassettes then there is no reason why you can't mix and match. I don't know why you think Sram is more future proof though - it's hardly like Shimano are going anywhere and, by the time you've paid for a new freehub you could be looking at spending an extra £50 for no reason.
Oh, and finally I too have long been a Shimano guy and REALLY wanted Sram for the bike I built up recently, but I could get a full M8000 groupset with brakes for around £400. Sram cost a lot more for a similar level. It was a no brainer in the end, but you should look at costs. Shimano is cheap but high quality. You can get cheap Sram stuff but it is a little higher in cost which mounts up over time. There is a reason Shimano won the value product award here the other day!
Changing a fundamental fitment standard is the easiest way to force new sales. Nothing is safe!
Not a SRAM fan, I've had no issues with any Shimano product in stark contrast with my SRAM experience where everything works great to start with but soon fails :-(
I have an 11 speed xt setup with a sram x1 casette. Also use a sram GX setup with a shimano xt 11s casette.
They're both interchangeable
These new "modern" drive trains seem like they would be shot after a season
I have an X1 and this looks to be a great replacement for when my cogs need to be replaced.
Add in the fact that you also don't need to change your chainring just to get enough gears on the descents, e*thirteen's TRS Race 9-46 Tooth Cassette is clearly a viable replacement/upgrade.
No need to buy a new shifter, derailleur, and chain, but still get a 511% gear range? Sign me up.
yeah...but call them! the price is very different!
actually what i meant to say was not the first 4 cogs that are very expensive but the second 4 cogs. these two pieces screw together. Ethireen also says that aligning these two cogs by screwing them together is something ehtirteen recommends doing at their factory. And the second sections of cogs is most important because that is usually where the chain line which gets the most wear.
There is a lot of waste on the consumer side of this industry, and people sometimes just dont get what the "wear-life" of components actually are. They'll pass them off as "used up" almost immediately, or at least after the first few races.
That being said.... now, if i can only get him to switch to these black beauties!!!! Bwaaaaahahaha!!!
even with my weak and feeble legs I can get up 99% of the hills with a simple 1x10 with just a 40t expander cog.
If you really need a 50t (bail out cog) maybe you should look at an e-bike!
Only in a technical sense: the reality is that we have a VERY liberal definition of "mountain" in the UK.
I'm just happy that I have hill's Mountains or what ever you want to call them close to my home and I get to play on them often!
Have a look at my original comment where I say "with all these ever increasing cassette ratios it feels like the bike industry is supplying us with an answer to a question we never asked!

Not once do I suggest that we need a 50t cassette!
You do know there are other country's right?
However, I've ridden the e13 9-44 cassette, and have spun that 9t down the road back to town after a big ride, specifically paying attention for excessive vibration. It's not an issue, and the extra range is certainly nice. I think these small cogs work on mountain bikes because you're not using it 100% of the time, but when you do, the extra range is worth the hard-to-detect extra vibration.
TL;DR It is not recommended to run machinery on a chain drive with a cog less than 11t, but it works on mountain bikes because the application is different than what the text books are referring to.
Just stating that friction and wear does in fact increase when the chain is wrapped more.
From link:
"For space consideration or for very low speeds, sprocket with less number of teeth may be used, by sacrificing the life expectancy of the chain."
9T is a no-no in chain drive design.
This is the most important concern about this product. Nobody seems to care because of lack of knowledge about this.
Still probably a couple weeks away from other suppliers having them.
I'm have been running one of the 10s cassettes since they came out. Nearly no wear, shifts like a dream, and light. on my second chain with this cassette. Will buy another when this wears out. I feel its worth it. ONLY draw back I can point out: can not use KMC sl dlc chains with it; only sram or shimano
Remember that you're not allowed to make that decision for yourself...
I tired that. the middle part cost $260.00, which is not advertised on Ethirteen website.
Where are you using the 9t cog?
