10.6 Adjusting Twenty-Seven Speed Cassette Chain
1.
Loosen, but do not remove the clamp that secure the crank handles to the fork.
2.
Slide the crank handles up and/or down until the proper tension on the chain is achieved.
3.
Tighten the clamp that secures the crank handles to the fork securely.
It may be necessary to turn the hand crank in a clockwise motion to position the chain on the small sprocket.
The proper chain tension will be approximately 1/2-inch of chain slack.
If crank is in desired position but chain tension is not correct, links MUST be added to or removed from the chain to correct the tension. This
should be performed by a qualified technician.
