Pre-ride checklist
□ Check the chain or belt
Make sure your chain or belt is in good condition and has the correct tension.
Rear cargo: Chain Front cargo: Belt
Roller
Check that the chain has no: kinks or rust,
and no broken pins, plates, or rollers.
Check that the belt teeth and belt roller
are not worn: the belt teeth must engage
with the teeth on the front and rear rings,
and the belt must stay inside the roller
sides.
Check the tension:
1. Shift to the smallest rear cog (rear cargo).
2. Rotate the pedals to four different positions and measure the slack at these four
positions and take the average. There should be between 6-12mm / 0.25-0.50in
total vertical movement in the middle of the chain or belt. Trek recommends the use
of a belt-tension gauge for best results.
NOTE: If there is a large difference between measurements, the front sprocket
may be misaligned. See your bike shop for this adjustment.
See Chain/Belt on page 4-6 for maintenance instructions.
