Tires
- Tire pressure affects traction, and tire life.
- Adjust the tire pressure to match road conditions and rider’s
preference, but do not stray too far from the recommended pressure.
NOTE
Tire pressure should be checked when the tires are cold before
riding.
Road conditions
- When the road is wet, muddy, sandy or slippery, reduce the tire
pressure.
- On gravel roads or hard terrain, increase the tire pressure.
Spokes and wheel rims
The spokes on both wheels must be tightened evenly and should
not be allowed to have free play. Unevenly tightened or loose spokes
will cause wheel rim runout, the other spokes will be stressed and
might break.
Wheel rim runout
Place a dial indicator at the rim side, and spin the wheel by hand
to measure the axial runout.
Place the dial indicator at the inner circumference of the wheel and
spin the wheel, the difference between the highest and lowest
quantities is the runout.
If the runout is not excesive it can be corrected tightening or loosening
some spokes with the spoke adjusting wrench
(B) . If the wheel rim
is curved or bent it must be replaced.
NOTE
A welded area on the rim may indicate excessive runout.
Disregard this when measuring rim runout.
