For a build I am doing I have two groupsets lined up. A Dura Ace/600 8-speed groupset and a SRAM Apex 10-speed. I always prefer going period correct, but I am not sure what period these cranks are: 8-speed or 9-speed era. Also, I am not sure if I can shift the front with a 600 derailleur or if the 10-speed chain will run on this if they are indeed 8-speed cranks.
Any thoughts on this?
