INSTALLATION AND ADJUSTMENT
3.8.2 Brake Adjustment
Disc brakes
When the wheel is out of the frame, do not operate the brake lever. With some brakes,
the pads automatically adjust their clearance such that you will not be able to re-insert
the disc.
Aligning a hydraulic disc brake
1. Loosen the two alignment bolts but do not remove them.
2. Slowly rotate the wheel and check the space between rotor and brake pads; adjust the
position of the brake pads so that the rotor is not rubbing and is slightly closer to the
outer pad (the clearance between rotor and pad should be just enough to prevent
rubbing). Make sure the rotor and pads are parallel to each other. Tighten the bolts when
the adjustment is finished.
WARNING:
If the disc rotor is curved or broken, please replace the rotor first.
WARNING:
Overuse or incorrect use of a front-wheel brake can cause the rear wheel to lift off the ground, resulting in decreased
control of the bike or even flipping the bike and rider in the forward direction; this can lead to serious injury and bicycle
damage. Be careful when applying the front brake, and avoid using it without also using the rear brake. Ideally, both
brakes should be applied at the same time, with the rider moving rearward on the bicycle depending on the amount of
braking pressure applied.

3.9 Shifter and Derailleur Adjustment
Rear Derailleur Adjustment
Step 1: Make sure the rear derailleur is shifted all the way down to the smallest
cog.
Step 2: Turn your barrel-adjuster all the way tight so that you have room to
adjust it later.
Step 3: Adjust the high limit by rotating the screw marked "H" on your derailleur
so that it lines up with that smallest cog.
Step 4: Tighten the tension in your cable by unscrewing the cable anchor,
pulling the cable tight, and screwing the anchor back on tight.
Step 5: Shift your rear derailleur to the 4th or 5th cog.
Step 6: To adjust the index, turn your barrel-adjuster so that the derailleur pulley
lines up underneath the correct (chosen) cog. With a Shimano rear derailleur,
you want to line up the pulley slightly inboard of the cog. Perform some practice
shifts to make sure it is adjusted properly.
Step 7: Shift your rear derailleur to the largest cog.
Step 8: Adjust the low limit by rotating the screw marked "L" on your derailleur
so that it lines up with the largest cog.
Step 9: Adjust the B-tension screw so that the pulley on the rear derailleur is as
close to the largest cog on the cassette as possible without dragging.
