Re: #25 Chain Drive Experience ???

We generally use #25 for mechanisms and #35 for the drive-train.

According to AM #35 chain is .25lb/ft and #25 is .10lb/ft. In a drive train that used 16ft of chain (average for us I think) #25 series would save 2.4lbs vs #35.

This weight difference could be reduced by using smaller sprockets and no tensioner with #35 chain. We've used half-links to tension our #35 chain drives during initial assembly, never touched them after that, and never thrown a chain in the 3 years I've been coaching.
