The crank will fit, but the derailer won't. It's set up for a Huret hanger. There are adapters, but I haven't seen one in years.

That T.A. Professional 3 pin is my favorite vintage double. New stickers are available for the arms.

I've been looking for one of those Competition forks for a long time. One showed up on eBay not long ago and it sold for $373!
