ASSEMBLY DERAILLEUR
Check the rear derailleur
hanger alignment. A bent rear
derailleur hanger will result in
inaccurate index shifting.
Attach the rear derailleur to
the frame’s rear derailleur
hanger.
Check that the b-adjust
washer tab (b-adjust screw at
DualDrive 24 and 21) is clear of the
rear derailleur dropout tab.
» Tighten the 5 mm hex hanger bolt
to 8 – 10 Nm (70–85 in.lbs.).
CHAIN LENGTH
Bypassing the rear derailleur,
run the chain around the
largest cog chainring combi-
nation. Add 4 LINKS or 3 links +
connecting link to this length for
proper chain length.
» For rear suspension frames,
position the rear suspension for
the greatest chain length
required.
