Step 13 – Connecting the Rear Derailleur Cable
What You Need

  • Torque Wrench (TW-1 or TW-5)
  • Socket and Bit Set (SBS-1)
  • Hex Set (HXS-1.2) 
  • Cutters (SP-7)
  • Pliers (NP-6)
  • Cable Tips/End Caps
Before You Get Started
  • Make sure you have completely unloaded your right shifter and properly aligned your rear derailleur (follow step 9 if not).


1.  Begin by turning the barrel adjuster clockwise all of the way to the end of its range.  Then back it off one full turn. 
2.  To connect the rear derailleur cable, make sure you have completed running your cable through the last piece of cable housing and the rear derailleur barrel adjuster. 
3.  Pass the cable over/through the cable guide (if applicable) and under the rear derailleur cable bolt (see Figure 1).

4.  Pull the rear derailleur cable tight removing all slack and tighten the derailleur cable bolt to the manufacturer’s recommended torque value.
5.  If this is a new rear derailleur cable it will more than likely stretch after shifting through your gears the first few times.  After shifting through the gears the first few times, be sure to back off the rear derailleur cable bolt and repeat the above steps.
6.  Once complete, cut the excess cable and attach and end cap (ferrule) (see Figure 2).

7.  You now have a properly connected rear derailleur cable. 
This completes connecting the rear derailleur cable.
