Retrospec KOA REV+ Assembly Instructions Manual page 16

• NOTE: For good shifting and riding experience, follow these 4 actions:
1. Shift only when pedaling (forward), do not shift when stopped.
2. Do not use hard, aggressive pedal pressure while changing gears.
3. Never back pedal when changing gears.
4.
Never force the gear shifting levers.
• Rear Derailleur Adjustment:
There are two limit adjustment screws on the rear derailleur - High/"H" and
Low "L". Looking from the rear of the bike forward, the limit adjustments
center the chain on the high/large and low/small rear cogs which prevents
the chain from going over the large cog and into the wheel/left (the "H" or
high adjustment screw) or into the frame/ right (the "L" or low adjustment
screw).
First, the derailleur cable tension needs to be correct:
Position the shifter(s) so the chain is on the smallest rear cog and largest front
sprocket - check for cable slack at point "B" (Refer to Fig. 19). If there is slack,
loosen the cable nut or hex bolt, pull the cable with pliers and retighten the cable
nut/bolt while pulling cable taut (tightening torque: 5-7N.m or 4-5 lbs.)
Spoke Protector
High/Large Cog ("H") Limit Adjustment
Turn the "high limit" adjust screw marked "H" on the rear derailleur so that, again
looking from the rear, the upper guide pulley is below the vertical plane of the
center of the top/large cog.
Low/Small Rear Cog ("L") Limit Adjustment
Turn the "low limit" adjust screw marked "L" on the rear derailleur so that, again
looking from the rear, the upper guide pulley is below the vertical plane of the
center of the low/small cog.
