WARNING: Do not attempt chain repairs. If there is a problem with the chain, have a
bicycle service shop make any repairs.
Adjust the tightness of the chain as follows:
• Loosen the axle nuts of the rear wheel.
• Hold the wheel in this position and tighten the axle nuts.
TIRE REMOVAL/SEATING
Before adding air to any tire, make sure the edge of the tire (the bead) is the same distance
from the rim,all around the rim, on both sides of the tire. If the tire does not appear to be
seated correctly, release air from the inner tube until you can push the bead of the tire into
the rim where necessary. Add air slowly and stop frequently to check the tire seating and
the pressure, until you reach the correct inflation pressure (see Figure
89
).

The chain must be at the correct tightness. If too tight, the bicycle will be difficult to pedal.
If too loose, the chain can come off the sprockets. When the chain is at the correct tightness,
you can rotate the crank freely and you can pull it no more than one-half inch away from a
straightedge as shown (see Figure
87)
.
• Move the rear wheel forward or backward as necessary.
NOTE: Make sure the rear wheel is centered in the bicycle frame (see Figure
88
).
