Yeah, I’ve never seen another tandem with front crossover drive. (See John Allen “How to build up your own tandem crankset” on Sheldon Brown.)
I bought it used. It is noisy because it has an idler to support the long chain span, but everything works well. I haven’t changed the chain yet.
….and we’re now two topics removed from commuting.. I use it sometimes to commute when my primary is down and I have compatible rack and pedals on the tandem.
