Chain Tension; Appendix A: Intended Use Of Your Bicycle - Tern Quick Haul D7i Bedienungsanleitung

6.H. Chain Tension
The chain endures huge tension forces from pedaling. For optimal shifting and
efficiency, the chain must connect with the gear teeth properly.
To check for excessive slack on derailleur systems, shift to the smallest gear on the cassette (if
applicable) to create the greatest amount of slack in the chain. Chain slack should be within 10-20
mm per span. This amount of slack is equally applicable to all internal hub gear chain drives.

DEALER: Belt drive tension is more complicated and should be serviced by dealers.
Excessive slack can be caused by a chain that is worn and stretched. A stretched chain will not sit properly in
the teeth. Over time, gaps between the teeth of the sprockets become greater, mirroring the shape of the
chain. Replacing a chain when it is worn will help extend the life of the most expensive cassette and chainring.
For internal gear hubs, excessive slack can also be due to misadjustment
of the rear wheel position relative to the dropout
DEALER: If you are not sure if the chain slack is from chain wear or wheel
misadjustment, take your bike to the Dealer for servicing.
