How to install your TRS+ Cassette
The 40t is available only for Shimano as SRAM does not offer a 34 tooth cassette. We find that these combinations work best.
Old drivetrain components could cause poor shifting performance. We recommend a new chain and a new or well-cared for cassette.
How to install your TRS+ Cassette
It’s a replacement B limit screw for your rear derailleur. The longer screw may be needed for proper derailleur set-up. If you are unsure about setting your B limit, refer to our how to guide, or head to your local bike shop.
How to install your TRS+ Cassette
It's really not too hard, but keep in mind that you are working at the extreme limits of your rear derailleur, so small changes can make a big difference.
We have some great how-to guides here to help you out.
If you are still struggling with the setup and adjustment, we recommend heading to your local bike shop.
How to remove your TRS+ Cassette
We recommend a medium or long cage derailleur for use with the EX Cog. If you are not sure about maximum derailleur capacity, check here to reference our handy compatibility chart.
The 42 tooth (42t) EX Cogs WILL NOT work with 34 tooth (max) cassettes. A 6 tooth jump is the maximum for excellent shift performance.
We don't recommend using the 40 tooth (40t) EX Cog with a 36 tooth cassette. Shift performance will be compromised as the timing of the shift features relative to the cassette will not be correct.

The cage capacity of 11 speed derailleurs will not support a size larger than 46T. A 12 speed derailleur would be required for a 50T cassette cog so due to this incompatibility, we do not offer the kit with a 9-50 cassette.
Yes. Yes, it is.
Compatible:
- SRAM:
- X1 11 Speed
- GX 11 Speed
- XO1 11 Speed
Not Compatible
- SRAM:
- XX1 11 Speed*
- Shimano:
- All Shimano 11 Speed
*Note: Early release info indicated XX1 Compatibility. However, it has come to light that SRAM has several versions of XX1 shifters, some of which are not compatible with the shifter ratchet upgrade. Due to this we are removing compatibility with XX1. While the XX1 Derailleur could be used, the ratchet supplied with the XX1 kit will likely not be compatible with XX1 shifters on the market.
Steel and alloy cassette clusters from TRS+ 9-46 11s (FW1TPA-102) and TRS Race 9-46 11s (FW1TRA-100) cassettes are cross-compatible.
Parts from TRS+ 9-42 10s and TRS+ 9-44 11s cassettes are not cross compatible with any other cassettes.
Note: this service applies only to Generation 1 TRS+ Cassettes, 9-42T and 9-44T.
If you have a newer, 9-46T 11 or 12 speed TRS+ or TRSr cassette with creaking issues, read the article here: Troubleshooting Cassette noise (TRS+, TRSr, XCX)
We have found that certain freehub bodies may interact with our cassette in such a way that noise can occur under load. We have made changes to newer production runs of the cassette to solve this potential problem.
Follow these steps to cure your creak, if you detailed install and removal instructions you can find those here: http://service.bythehive.com/c/Cassette
Step 1:
Grease under the 9-10t cogs on the steel portion of the cassette. 
Step 2:
If greasing doesn't solve your issue, contact your nearest distributor for a creak fix kit. The kit includes a spacer and small PTFE washer.
Remove your cassette, install the silver spacer under the cassette
Re-install the aluminum cogs and lockring
Install the PTFE washer and make sure it is seated on the XD driver
Re-install the steel portion of the cassette.
