Install derailleur and shifter cable
A. The new derailleur will fit and thread into the hanger at the same attachment point
where the chain tensioner was located. Use a 5mm hex wrench to tighten into place.
Make sure the pin on the derailleur is set into the groove on the back of the dropout
plate.
B. Run shifter cable through cable housing.
C. Properly route shifter cable housing from the shifter through the left fork stanchion
and the underside of the bike’s frame, ending at the derailleur on the driveside. The
cable and housing may need to be properly sized at this point.
D. Pull the cable tight and attach to the derailleur. Tighten with 5mm hex wrench. To
tighten the cable, shift the lever several times as if to change into a bigger sprocket or
chainring. This will settle the cable into place and apply tension on it; the cable must be
taut.
Install the crankset
A. Make sure cranks are placed in opposition of each other and then tighten the crank
screws into place.
B. Install the pedals on each crank.
Cut new chain to size and install
A. Run the chain around the chainring and over the largest cog in the 10-speed cassette,
bypassing the derailleur.
B. Line each end of the chain up to where an outer rivet meets an inner one. Once met,
extend the chain an inch (about 2 rivets), to account for the derailleur.
C. Mark that rivet an inch (about 2 rivets) down from the meeting point with a marker, that
will be the chain cutting point. Ensure both rivets have an outer and inner piece.
D. Use a chain breaker to break the chain at the marked link.
E. Feed the chain through the derailleur, first, over the “under pulley” and then through
and under the “upper pulley.” Guide chain around chainring and connect the inner and
outer rivet with a master link.
F. Work the cranks and move the shifter ensuring the chain is grabbing each gear
smoothly. Adjust tension as necessary.
