I know I am bumping an old thread here but I need some advice as to the best place to find cranks for this bike. I realize it was quite a few years old but I just got a Crestline tandem and need the (back) crank replaced, and had no luck on ebay so I was wondering if you could give me any advice. I am an amateur and don't know places or ways to search for the specific piece, but I took it to a bike shop and said the best place to find it is online. Thanks for the help!
