How to install the e*thirteen TRS+ 12-speed upgrade kit

Kamil 25. June 2018

Installing the upgrade kit takes a little finesse, but with our step-by-step guide, you’ll have it done quickly.

With the new e*thirteen TRS+ 12-speed upgrade kit it is now possible to take all SRAM 11-speed MTB groupsets and upgrade them to 12-speed!

The TRS+ 12-speed upgrade kit includes everything you need to upgrade your drivetrain and most of the tools. Even the necessary grease is provided, leaving nothing to chance when you upgrade. Below is a step by step guide on how to convert the trigger shifter and rear derailleur so that they can handle the range of e*thirteen’s TRS+ 12-speed cassette.

Tools needed

e*thirteen has included almost everything you need for upgrade to a 12-speed drivetrain. This includes 2.5 mm, 3 mm, 4 mm, and 5 mm Allen keys as well as a square drive and T25 bit chuck. 2000 mm of cable housing, grease, chain and the small parts necessary to completely convert are also in the box. The only extra tools you need are for removing/installing the cassette. These can be seen in the pictures below.

Step 1: Converting the derailleur

Step 1: Converting the derailleur

Removing the derailleur

  • First, remove the rear wheel from the bike. Loosen the shifter cable and unscrew the derailleur from the derailleur hanger.
  • Now, remove the upper and lower jockey pulleys and clean them.

Tip: The pulleys are marked with L for the lower and U for upper. This will help you put them back in the right position.

Converting and reinstalling the pulleys

  • Re-grease the cleaned pulleys
  • Add the e*thirteen spacers to the pulleys and reinstall them. Be careful to use the longer e*thirteen bolt for the lower pulley and the shorter e*thirteen bolt for the upper. Only tighten he pulleys to 2 Nm.
  • Now, the converted rear derailleur can be bolted back on to the frame

Note: Only the outer pulley spacers are exchanged with the e*thirteen spacers. These new spacers increase the distance from the derailleur cage from 8 mm to 9.5 mm. This allows the derailleur to get to the lowest sprocket.

Removing the shifter and shift spool assembly

  • Remove the shifter from the handlebars and click the smallest lever until it shifts into the most difficult gear. (Pull the cable while doing this.)
  • Remove the housing cover and the shifter cable.
  • Flip the shifter and unscrew the 3 mm bolt to remove the lever.
  • Remove the 3 bolts from the underside of the shifter. Make sure to hold everything in place.
  • Now, install the Claw with the 3 bolts that were removed from the underside of the shifter.

Note: When screwing in the 3 bolts, make sure to use the smallest one on the hole that is surrounded by metal.

Exchanging the ratchet and shift spool

  • First, remove the spring. Be careful not to bend it.
  • The Claw is only used to help you remove the ratchet.
  • Using a 3 mm key and a Torx T25, replace the red spool and ratchet with the black e*thirteen version. (Don’t forget the washer if necessary.) Make sure everything lines up and then screw the assembly back together.

  • Reinstall the spring, lever and shifter cable.
  • Screw on the cover and the shifter is finished!

Tip: Do not use grease on the bolts. Instead use liquid screw lock.

Step 3: Installing the TRS+ 12-speed cassette

Step 3: Installing the TRS+ 12-speed cassette

  • First, remove the old cassette and clean the freehub body.
  • Grease the freehub body with the included e*thirteen grease.
  • Now, the 12-speed cassette can be installed.
  • First, place largest two sprockets over the XD freehub body
  • After, tighten the clamp to 3 Nm.
  • Grease the contact points between the two sprocket clusters.
  • Place the second sprocket cluster over the freehub body so that the arrow lined up with the open lock symbol.
  • Now, with the help of a chain whip, tighten the second sprocket cluster in a clockwise direction until the arrow lines up with the closed lock symbol.
  • Both clusters are then connected with a small bolt that needs to be tightened to 3 Nm.
