1970's LeJuene Help?

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

To repeat MYSELF, you can re-space almost ANY (there are some exceptions) SHIMANO FREEHUB to 120mm if you have the will & money, so the frame-itself, does not have to be respaced. A Shimano ACERA hub (135mm) is actually one of the cheaper hubs, and it can be converted without buying/cannibalizing any additional hubs. I am pretty sure that you can stack a 7-speed cassette (or, an 8-speed MINUS one cog) on the shorter freehub ... [/QUOTE]


I don't want to hijack the topic here, but I'm interested in doing this because I've got an old Peugeot with 120mm spacing that will need a new hub some time soon. It is currently spread to fit a 126mm Maillard Helicomatic hub (I'm no Peugeot expert but this seems odd given that I thought the helicomatic hubs were original equipment for this bike). So I'd either want to downsize a 130 cassette hub to 120, or maybe just to 126 given that that is what I've been riding round on without any problems. I guess my question is: what is entailed in respacing a hyperglide cassette hub - cutting down the splined freehub body? Different spacers/cones etc? Are there any chainline issues in doing this?

Cheers!

I need to correct myself -- I think that if you were to buy an ACERA hub that you would need different cones ...

Changing cones wasn't an issue for me because I actually bought the ACERA hub for the 36h rear hub shell ... and, I actually wanted the large-shell, Parallax hub for a particular wheel.

I knew when I bought it that I was going to cannibalize a "standard" freehub body from a 32h hub to make the ACERA hub good-to-go for a regular 9-speed Shimano cassette.

The "shorty" 7-speed freehub body on the ACERA became something that was lying around UNTIL I had a Du-Oh! moment & it occurred to me that it just might be the same length as the original 7-speed Freehub body (which was about 5mm shorter than the "standard" Freehub body length) ... so, if I removed the 4mm, non-driveside spacer on a Shimano 130mm ROAD hub & transplaned the "shorty" Freehub body, I could end up with a close-to 120mm rear Freehub ... that is, a hub which could be used on any vintage frame for which re-spacing the rear triangle was/IS not option!

Consequently, I opted for a Ultegra 6500 rear hub because I was after a more-or-less retro-look (i.e., no "bell" on the driveside) ...

So, after swapping the Freehubs (you will need a 10mm L-shaped Allen wrench which you can put a cheater bar on OR Herculean strength if you have a T-handle Allen wrench), I just used the cones & nuts from the Ultegra ROAD hub sans the 4mm spacer ... shortened the axle, and I was good-to-go.

So, good-or-bad, the left-right flange offset is "the same" as on a typcial 120mm spaced rear hub, at least, the ones I have; so, no chainline issues for me to speak of.

BTW. In theory, you could fit eight 9-speed Shimano cogs + a 1mm spacer to run an "9-speed" Shimano indexed shifting in a 120mm frame ...

OR, presumably, nine 10-speed Shimano cogs + a-spacer-of-unknown-width to run "10-speed" Shimano indexed shifting in a 120mm frame!

Of course, you do NOT need to use indexed shifting with any of the Shimano cassettes ... and, you should be able to simply slide a 7-speed Shimano cassette onto the "shorty" Freehub.

I don't know if the Maillard Helicomatic hub was standard to your bike, but it was common on many Peugeots in built through the early 80s.

Thanks for your explanation, alfeng.


I have been re-reading the late Sheldon Brown's info on freehubs and he seems to confirm what you say when he comments that "A frequent reason for body transplantation is to convert a 6- or 7-speed Freehub to use 8-/9-/10-speed cassettes. This generally will increase the over-locknut dimension (http://www.sheldonbrown.com/gloss_n-o.html#old)." Going in the reverse direction to a 7sp freehub body should therefore reduce the OLD.


I see that Acera M290 freehub bodies are available, so I will give this a try, probably with an 8 or 9sp cassette with one cog removed on a 105 or Ultegra hub. I am using what I think are the original Simplex friction shifters, but it is nice to know I could use STI if I went mad and decided to spend more on it...

It's on eBay.

Just listed it, $29 starting bid and NO RESERVE.

Go get it guys!

Item # 2302363859803 in case anyone is interested.
High bid of $34.33 so far but I still have 9 days to go on the auction.

You're new at the ebay game, aren't you. Generally, the serious bidding doesn't start until the last day. You're getting "feeler" bids now--they're just testing the waters, seeing who else is interested.

Good luck.

Yep,

I've bought stuff on eBay before but haven't sold yet.

Most action happens in the last two hours before it expires in my past experience. I love these "testing the waters" bidders, like it's gonna sell for $34. Get real!

Somebody has to get the ball rolling, why don't you throw in a couple hundred dollar bid for fun, I heard you're rich!

I heard you're rich!
You heard wrong.

You heard wrong.
Just teasing. Boulder, Colorado is pretty though. I assume that's Boulder County and if I recall, real estate was pricey. How's the riding trails?

The auction is up to $102.50 already, surprised it's been bid up that far so soon. We'll wait until the real action starts.

I got in when things were still cheap.

We get the mountain bikers from all over the north front range to my town to ride the Bitterbrush and Antelope trails at Hall Ranch county open space. Gorgeous and challenging.

I just ride roads, now. We're a destination starting point for that, too.
