Sachs - Chain Tension

The chain on my sachs looks a bit loose. I can move the chain upwardly about 1.5'' from its resting point in the middle of the chain. Should it be tighter? or is this fine?

Move the lower chain portion up and down. The measured distance should be 25-35mm ( 1 to 1 3/8"). If the chain free play is not within specified distance, adjust. This is taken from the owners manual.

I moved the lower chain portion up and down, and the distance was about 1.6'' .. if the manual says between 1'' and 1.375'' (1 3/8) , is 1.6'' going to hurt the performace?

No, not really. The worst it might do is slip off after you hit a bump. Tightening too much hurts but not too loose. There is no reason not to tighten it to the right setting though.


Re: Sachs - Chain Tension doublecheck the tension, just have a friend sit on the bike that weighs about what you do or at least 160 lbs. If the bike has a swing arm type suspension, the chain will tighten some when you sit on it. If when there's weight on it, it has 1/2" up and 1/2" down play,total one inch movement or a hair less, you are okay.

This can vary widely though if an axle is bent or the sprocket on the rear is out of round or worn unevenly. don-ohio (:^)
