Dang, that is extremely cool. This is the first I've ever seen or heard of this use of a kit wheel.

Andy--there might be a market for a small aluminum sprocket with a bearing pressed tightly into it.
McMaster sells steel idlers like that....they're kind of heavy and big.

If AM' sold something like this, I think alot of teams would be interested (including us, as we no longer have any extra KOP wheels)

(Ingenuity aside...) Why use a bearing when nylon has been proven by many teams to be just as effective? Even a brass bushing would be less expensive and probably lighter than a bearing. The efficiency loss between the two is somewhat nominal; this year's FTC shooters are a good example.
My current favorite chain tensioner sprocket:

At the very least I would take 3 of those bolts out to save some weight, all 6 probably isn't necessary for an idler.
