Single speed bicycle chain.

I was at the recycle depot looking around for stuff that I might use. There was a garage door track with the chain still on it, bought the chain only works great on single speeds.

Yep, same style chain. I bought a bunch of longer chains that I think were built for garage door applications. I paid a buck apiece for them. Not the greatest quality chain, but for the price I can just change them out on my bikes as often as needed.

I checked a couple that I had, KMC, and they were 3/8". I pitched them after saving them for years!
