3.2 ROUTING THE DERAILLEUR CABLES / WIRES AT THE BOTTOM BRACKET
OPTION A: STANDARD CABLE
 Rear derailleur: Route the rear derailleur cable housing through the large hole going into the drive-side chainstay.
TECH TIP: To help guide the rear derailleur cable housing through the chainstay, run a gear cable through the chainstay starting at the
dropout and exiting at the bottom bracket cable guide port. This will help guide the housing through the chainstay and out the dropout.
 Front derailleur: Trim the front derailleur cable housing to the appropriate length to insert into the cable noodle, then route the noodle into the non-
drive-side hole going up toward the seat tube. This noodle acts as a cable stop, the cable will be bare leading to the front derailleur.
OPTION B: ELECTRONIC WIRING
 Rear derailleur: Route the rear derailleur cable housing or wire through the dropout hole and out the large drive-side hole at the bottom bracket.
 Front derailleur: Route the wire through the hole in the seat tube and out the small non-drive-side hole at the bottom bracket.
 Join the connectors according to the manufacturer’s instructions, then place any excess wiring up into the frame in front of the bottom bracket shell.
TECH TIP: For Di2 instructions, refer to Shimano guide SM-EW79A-I, document SI-0100A.
