A good use for old Uniglide wheels / hubs -- single speed

Uniglide is an evolutionary dead end, however here is a use for the old wheels.

I know I have posted this bike before, however as I was making some modifications to the bike (now, even more ballastic) I realized I may never have let you in on the fact that I used an old set of Uniglide wheels plus a Performance conversion kit to turn it inot a single speed. The spacers do not have the Hyperglide wide tooth and fit perfectly.

I'm pretty sure the threading on that little cog is the same as a bottom bracket lockring. If you want a cleaner look, that is...

The other thing you could easily do with most uniglide hubs is to modernize them by transplanting on a hyperglide freehub body. It's quite simple and sheldon brown offers good instructions as always. I have done a wheelset myself and it was a piece of cake!

Isn't the tool for freehub swaps a pain to get ahold of? I've been looking off and on for a while with little luck.

IIRC, you can't do it on the earliest of freehubs. Some perhaps, but by then; chances are, one will find a combined UG/HG compatible unit.

P.S.: Of every Shimano goof ever made, UG cassettes are arguably the most irritatingly prolific. I have a shed full of wheels that need to be re-laced thanks to these things.

P.P.S.: One can make a decent freewheel-based SS wheel without having to re-dish as well: Take a Suntour Perfect freewheel, spin off the two outer cogs, pull out all the inboard cogs and spacers, and re-install one of the two threaded cogs. Chainline usually comes out pretty good.

I believe you're referring to the Shimano freehub disassembly tool (to access the pawls and bearing balls). To remove a freehub body simply requires a 10mm hex key.
Some models need a 12mm. But those may be the Joytech clones.

While it is true that the early UG freehubs bodies aren't swappable, I have had luck with most 7-speed freehubs, and WNG is right, all you need for the swap is a 10mm Hex key in most cases. Dura ace Uniglide is different, and requires a special tool AND freehub body to do the transplant, neither of which seem to be readily available.

You say that you've been able to do it with 5-speed freehubs as well; what model were they?

Whoops I missed this post somehow. I haven't tried doing the swap with 5-speed freehubs, but I know that Sixty-Fiver has done a swap from 6 speed UG to 7 speed HG on a peugeot he has been working on. I'm not exactly sure where the limit is for doing the swap, but sheldon brown makes a distinction in his article about freehub swapping, although he describes the non-swappable hubs by their physical characteristics, not by the shimano part numbers.

What were the PN's on the hubs that you and Sixty Fiver worked with?

Far as I'm concerned, Sheldon's advice is 1/10ths basic advice, the other 9/10th generalized hogwash; I've learned not to take his writings as gospel.
