Dura-Ace road hub cone wrench size?
 

I've got a set of Dura-Ace wheels in need of a basic bearing overhaul. Having already learned to do headset & BB overhauls myself, I'd like to do this myself as well, but I'm having trouble finding out what size cone wrenches I need to get.

It's an 8-speed hub set, either 1996 or 1997. Does anyone know what size cone wrenches these hubs need?
Thanks!

More than likely its a 13 & 15, the lock nut might be a 17. Just buy 2 of each, and unless you get into bmx, those are the only ones you'll need.
