shifting performance. check then for any sign of rust, fraying, kinks, broken strands, and any
damage to the cable housing. If you find any problems, the cables may need replacing before
your next ride.
Lubrication
All the pivoting points of the front and rear derailleur should be lubricated with light oil at
least every month. Be sure to wipe off any excess oil to prevent attraction of dirt into the
mechanisms. the shifting cables should be cleaned and re-coated with a thin layer of grease
every six months, or whenever new cables are being installed.
Adjustment- Rear Derailleur
Find a way to lift the back wheel of your bicycle off the ground
so you can turn the pedals forward. shift the chain to the smallest rear cog and the largest front
chainwheel, and loosen the
cable-fixing bolt. Position yourself behind the bike so you can easily check the alignment of the
chain, rear sprockets, and derailleur pulleys.
to adjust high gear, turn the adjustment screw marked “H” until the top guide pulley lines
up with the outside edge of the outermost sprocket. If the position of the guide pulley is set
beyond the outside edge of the sprocket, the chain will come off when pedaling. If the guide
pulley is set too far toward the larger cogs, the chain wheel may not shift onto the small
sprocket. Re-tighten the cable-fixing bolt.
at this point the cable must be checked and adjusted to eliminate slackness with the right
shifter all the way to the low position (fully forward for down tube shifters, fully back on MtB
top bar shifters). If there is too much slack, loosen the cable fixing bolt, pull the cable taut, and
re-tighten the bolt.

Derailleur
Although the front and rear derailleurs are initially adjusted at the
factory, you will need to inspect and possibly readjust both before
riding the bicycle.
Rear Derailleur
Begin by shifting the rear shifter to largest number indicated, dis-
connect the cable from the rear derailleur cable anchor bolt, and
place the chain on the smallest sprocket. Adjust the High limit
screw so the guide pulley and the smallest sprocket are lined up
vertically. Reconnect the cable, pull out any slack, and retighten
the anchor bolt securely. Shift through the gears, making sure
each gear achieved is done quietly and without hesitation.Shift the
rear shifter to the gear one and place the chain on the largest cog.
Adjust the Low limit screw in quarter turn increments until the
guide pulley and the largest cog are aligned vertically. Again, shift
through each gear several times, checking that each gear is
achieved smoothly. It may take several attempts before the rear
derailleur and cable is adjusted properly.
Note: Some bicycles may be equipped with a rear derailleur
mechanism that works in reverse to the directions above.
Some derailleurs may have an adjusting barrel (see drawing). Use
the adjusting barrel to fine tune the adjustment of the chain loca-
tion. Turn the adjusting barrel clockwise will move the derailleur
outboard - away from the wheel, while turning it clockwise will
direct the chain inboard - towards the wheel.
Ensure all bolts are secured tightly and the chain
does not fall off in either direction.
