I am looking to install a triple chain wheel on my old road bike. The frame is a custom 531 db sport tourer built around 1980 and I think it has an english bottom bracket. My thoughts are to rob a crankset off of a mtb to install on my road bike. Will any of the mtb cranksets interchange with my current crankset? I have been away from cycling too long so the technology has passed me by.
Thanks for your help.
