No one can say what sizes you factually have, cone wrench wise. Many might speculate, as I can too. 13mm, 15mm cover the vast majority of cones on Asian made loose balled hubs, with an open wrench serving the lock nuts. but there are exceptions of 14, 16, 17 and even 19 that I've seem. The only way to be factually sure is to measure your cones, easiest done with a cone wrench acting as a gage.
Go into your LBS and ask them to "measure" then buy the right sizes from that shop. Andy.
