That is a wheel that is adapted from a recumbent. It acts effectively as an extra tensioner when the chain is ran around it, allowing me to boost the gear range beyond what the standard tensioner of a derailleur would allow.

You presumably have a good point there. I still had a bit of darkening in the leg, source of which I had a hard time tracing down - of course it may also be a combination of things.
