ment handle.

with your fingers. Reinstall the handlebar/seat post and adjustment

SYMPTOM: Knocking noise or play felt in pedals/crank
1. Inspect the pedal crank arm bolts. If they have loosened, apply
Loctite ® on the crank arm bolt threads and tighten.

for looseness. Tighten if necessary.

cups and try to rotate the bottom bracket shaft. If it does not rotate,
