Came about some NOS. Wondering if they work with 9 or 10 speed.

I think the early ones were 6-speed and the later ones were 7-speed. If you have the 7-speed version, then it should be okay with a 9-speed system. Would love to see some pics. I remember them being nice looking cranks. Do you have the Biopace rings with it?

No Biopace rings on them, just dual SIS. I think, but not sure, the Biopace rings came later on for the 7 and 8 speed. These cranks are the early 6 speed. Finish is beautifull; just like the pic from VELO base.
