Chain adjustment
The chain on your Schwinn
®
Evolution
®
Bike has been factory set and lubricated. It should not require any immediate
attention. Over time however you may need to make minor tension adjustments.
1. With an adjustable wrench, loosen the two bolts (A) on either side of the flywheel.
2. Tighten the two smaller nuts (B) which go through the frame tube evenly by turning clockwise until there is
approximately 1/4” (0.64 cm) of slack in the chain.
3. Tighten the two larger nuts (A) on the sides of the flywheel.
nOTE:
Make sure you adjust both sides equally so that the flywheel remains in alignment with the frame.
