older dura ace
I bought a pair of wheels that are dura ace hubs laced to mavic mach 2 ceramic rims.The rear hub in the picture has threads on the end of it so I'm thinking it is either a 6 or 7 speed hub. I don't suppose I can put a 8 or 9 speed casett on the hub can I? My road bikes are fairly new so they will easily take a 8-9 speed hub.

No, that is for a 5-6spd freewheel most likely, which threads on. Spacing of the hub is probably 126mm, modern bikes are 130mm. Your 8/9spd setup requires a freehub for the cassette to slide onto.

Hey thanks for the pics. Mine is like the bottom one except it has threads on the end of the barell. So a casett slides onto mine but how can I tell what size casett.. such as 7, 0r 8? Thanks again.

I'm having a hard time with this "barrel" you speak of. Are you perhaps referring to threads inside the end of the freehub body, like where the lockring threads in to hold down the cassette? Either way, if you have a model # of the Dura-Ace hub, that is the fastest/easiest way to tell without measuring.

If you're not sure if it's a cassette or freewheel hub, see:

I read through the articles and it appears the rear hub takes a cassett. It looks like it is the uniglide since there are threads where the smallest cog would screw on. Your article said replacement cassetts are hard to find. The rear hub then, either needs the modification or a newer hub. What does the modification cost? Your article said the wheel had to be redished. Seems like it might be easier to replace the hub?

Look on the end of the freehub body. Some Shimano freehubs that have the Uniglide external threading also have the internal threading for a Hyperglide lockring. If yours does, it will likely be a 8/9-speed hub. My Ultegra hubs from the mid-90s have this "duality" but I don't know if Dura-ace ever did.

It was not possible due to the smaller diameter of the Dura-Ace Uniglide thread.
