Re: pic: prototype drivetrain v2.1

I am not sure if this is what you are trying to convey in your above image so if not consider this. Using your pivot shaft as a jack shaft will enable the chains to freely rotate and stay tensioned throughout the range of suspension. You can determine the center distances for chain runs with an even number of links and then do not require external tensioners. Here is even an calculator to do it for you. http://www.botlanta.org/converters/d.../sprocket.html

As for if this drive needs a suspension or not totally depends on your team and it's engineering decisions regarding the application for this drive. Keep thinking outside of the box it will serve you well in the future.

There are no absolutes in engineering decisions. People and organizations value different things and out of context it would be wrong to make assumptions on the necessity of a feature.
