CHAPTER 3: COMMON ADJUSTMENTS
Flywheel Adjustment
Chain tension/Flywheel Alignment
Over time, the chain on your CycleOps IC will stretch due to the load applied to it. The following instructions will aid you in prop- erly tensioning the chain and aligning the flywheel in the frame of the CycleOps IC. CAUTION: Improper chain adjustment will cause premature wear and may void the warranty. ** CAUTION: NEVER put hands into or near the drive train while it is motion! **

Use a 17mm cone wrench to hold the axle locking nuts into place. Do not turn the wrench, it is only to be used as a sta- bilizer. With your other hand, use a 15mm box wrench to loosen the acorn nuts on the axle. Repeat this process on each side of the flywheel.
NOTES:
Be sure to make small adjustments to the drive train. Adjust both sides of the tensioning hardware. Only adjusting one side will lead to improper flywheel alignment and unwanted drive train wear and/or noise. Adjusting the tension/alignment is a difficult task and improper adjustment can lead to premature chain/cog wear. This is not covered under warranty. The chain tension has been adjusted properly when there is little or no play felt when the pedals are rocked back and forth.
