*Long length chains (more than 136 links or so) for our Joe Appaloosa, A. Homer Hilsen, Clem, Susie, Gus, Yellowolley, Platypus, and Atlantis.

If you don't know what length chain to buy for your old bike, take off the old chain and count the links.

Most chains everywhere are sold in regular 116 link length which is not long enough for most of our current bikes.
