NOT A 600XD, this might be a predessor to the 600. I want to use this triple crank with a 10 speed chain on my touring bike that has a 10 speed rear cog. Does anyone know if the 10 speed chain will work with the Sugino 500? I curently am using a Shimano RSX 7 speed crank with the 10 speed chain w/o issues, i just want to put a nicer crank on the old gal.
