Chain Tension & Adjustment
The chain on your bike has been factory set and lubricated. It should not require adjustment initially. Over time, however, you may need
to adjust the tension.
CAUTION:
Improper chain adjustment will cause premature wear and may void the warranty.
To adjust chain on Spinner
®
PRO+:
1. Using a 3mm Allen Wrench, remove the three screws
supporting the plastic chain guard shroud. (Figures 4)
2.
Using a 16mm or 5/8” socket and socket wrench, loosen the
axle nuts on both sides of the flywheel.
3. Using a 10mm open end wrench, loosen the lock nuts on the
chain adjustment screws.
4. To tighten the chain, turn the adjustment screw in a clockwise
rotation equally on both sides using the 10mm open end
wrench. (Figure 2A & 2B).
5. To loosen the chain, turn the adjustment screws on both
sides counter-clockwise using a 10mm open end wrench.
6. While adjusting the chain tension, work on both sides of the
flywheel. Adjust the angle of the flywheel so it is straight front
to rear and evenly spaced within the frame side to side.
(Figure 2A & 2B).
7. Align the chain so it runs straight on both of the sprockets.
8. Adjust the angle of the flywheel by adjusting the adjustment
screws on both sides of the flywheel. Test by slowly rotating
the pedals.
Note:
If the chain is stretched beyond adjustment, the
replacement of the chain is recommended.
When alignment is at the optimal adjustment, the chain
will run smoother and quieter.
9. Tighten the adjustment lock nuts and axle nuts on both sides.
10. Install the chain guard shroud and re-test the bike.
