Alright I'm building a bike up at my local co-op. I found a nice rear wheel there, however it has a unique hub. One of the volunteers there was telling me about it. It was as he called "the transition between a freewheel and a cassette". It was called something along the lines of a "Michod" hub. The whole thing is like a screw and there there's a lock ring that holds everything in place.

However the hub is missing the lock ring and the the co-op doesn't have a specific tool needed aswell. He said I could use it if I could find those part, most likely on ebay. But in my absent mindedness I forgot the exact name of the hub. Can anyone shed some light on this?

Helicomatic hub?

That was it. No idea where i got michod from.

Bwaaa Haaaa Haaa! Welcome to helicomatic hell! In fact, there is at least one other thread running right now on them. Either here in C&V or over in mechanics forum.

Maybe there is nothing wrong with them, but in any case, they are a dead, unsupported technology, so its hard to work with.

Last set I had I traded to another extremely optimistic BF member. How's that working out for you Redneckwes!?!

After reading about it, and checking out the price for tool and lockring. I may be better off just finding a different wheel. Its a shame it was a nice wheel.

You don't need the tool. Channel locks with a bit of finesse work just fine. Obtaining the lockring though... maybe not so easy.

I replaced a spoke on one and somehow the bike shop that did it was able to get cassette off with out the spcific tool. I could tell there was some stripping involved, but they got the job done and I promptly sold said bike after reading about the hubs on here. Planned obselescence, or maybe just hoping you had to also spend money on the tool also to service it....

They all require a special tool to service them.

I can't imagine owning a wheel where I couldn't replace the cogs themselves. Is this not a problem?
