tricolor hubs question

[AngryScientist]

these jobbers:

just to confirm: OK to run 9-speed cassettes and 130mm spaced rear - right?

I believe that the uniglide-only 64xx hubs were 126 and the dual uniglide / hyper glide hubs were 130. Should be 130. No problem with a 9V cassette.

thanks.

i admit i dont know anything about uniglide/hyperglide! as long as a regular cassette fits, i'm good.

i'm planning on a winter overhaul of these and then build them into a more classic set.

Once again, it's the late, great Sheldon Brown to the rescue. Scroll a quarter of the way down this page for a good description of uniglide, hyperglide, and compatibility with different cassettes:

perfect, thanks greg!

If it's 130 spaced now, you are good. I have done an axle/cassette swap to change from 126 to 130, easy enough to do.

looks like i'll wait to see what comes in the mail.

fortunately, i paid $15 for this set, so it's not a very big gamble.

While it is cheap and easy to do an axle swap, the problem would be that if it is currently a 126mm axle, then it will have a 7spd freehub body (which won't fit 8/9/10spd cassettes).

Op if you need the rest of the group let me know... my shifters are 8 speed tho.

Ahh, I meant freehub, not cassette. Hadn't had my coffee yet. In fact, the hub I did the surgery on is still going strong 10+ years later.

I laced a 32/28 set of these hubs to A23s and they are flat out great. So smooth.

Looks like you snagged a 7400 skewer in there? Nice.

Good news: they are indeed 6402 type hubs, so 130 overall and cassette compatible.

bearings feel smooth, but a little dry. going to overhaul these over the winter.

anything special to note on the OH? Standard loose bearing hub procedures i assume.

Shimano still has PDFs of the hub:

6400/6402 hubs are awesome. I had a set that outlasted 3 pairs of rims. I had them from 1997 until last year. I sold them (as part of a wheelset) through the forum. I expect that they are reliably serving their current owner today. Yup, standard cup/cone/loose ball bearings. Use grade 25 stainless ball bearings and they should be super smooth. Take a close look at the freehub body to ensure it doesn't have any cracks.
