Advice on gear cluster - 5 speed for french size hub

Hello to everyone, I just found your forum while searching for information on a 5 speed gear cluster for a mid 1970's Campy hub. One of the posts on this forum came up during that search. I was looking for info on what thread type was on the hub, because I wanted to change it. The post I found helped me identify it as a "French Thread" hub.

I have a couple of questions that I hope someone can answer,

1,) How hard is it to find a 5 speed cluster with French Thread?
2.) The gear cluster I removed is a Regina with interchangeable cogs. I want to change the cogs to give me a lower gear ratio. Are gears still available?l And if they are, would anyone recommend a source?

Thanks in advance.

Unlike standard and italian threading, Sheldon says you can only use french with french. So, if your hub threading is french, you're stuck with the vintage market ... unless you change out the hub and rebuild the wheel.

I would think a C&V forum member could help ... and ebay.

Working, removing and replacing cogs, on a Regina freewheel body can be rather frustrating depending on the cogs tightness and one's tooling. I've done a fair amount of this with the Var and regina tooling back in the day and found it challenging at best. Far better is to find a SunTour French threaded freewheel and then swap out cogs if needed. Andy

Thanks for the info guys. I didn't know how difficult it would be to remove and replace gears on the Regina cluster. It is 40 years old, so I thought it would be difficult.

I don't want to replace the Campy hub. It is original to the bike, so I will check out your suggestions on finding another gear cluster with a different set of gear ratios. I appreciate the responses. Ken M.

You might want to post some pics of the wheel (and the bike) on the C&V forum. You'll get some ideas of how best to deal with this. Once you figure out what you want, you can put up a WTB ad in the C&V forum. Something is bound to turn up.

Have you considered finding a wheel with an identical Campy hub but English or Italian threaded to ride, and keep the French one for when you pass the bike on to a new caretaker or display

French bike manufacturing made their own cul de sac buy using an exclusive set of standards .. and hugely lost market share as a result..

If you want to ride the bike, change wheels to something you can find parts for, : british /asian/ ISO..

since no new Regina cogs are available you have to compete at auctions for long hidden supplies . with collectors..

Thanks for the comments. I was not considering replacing the hub with an English or Italian one. I was really just looking for the quickest fix to get a lower gear set. The Regina cluster is 13-17. I have another wheel with a 15-20 on it. I will just ride that wheel until I find another cluster with a lower ratio. I'm in no hurry, so I'll just keep my eye open for another 5 speed cluster.

A little off-topic, but ...

I see this comment from time to time. The world (except the US) was moving from Imperial to Metric. France was betting everything would eventually be all metric. They made a bet and lost, but who predicted this? It wasn't obvious at the time.

Yea things like tubing diameters remained stubbornly inch based

Italy bought machinery from England so things like their BB thread is fractional in pitch and metric diameters .. mixed..

If all you want is are across-the-range lower gears, an easier way to achieve that is by changing your front chainrings.

Given the age of bike it's likely a 144 BCD and a 42 small chain ring with 41 as the smallest that fits that BCD.

Yes ... but perhaps it is 144 and perhaps it's not. The OP didn't say. Plenty of vintage cranksets (a lot of them French) have BCDs well below 100mm. Of course, it may be hard to find rings for some of them. If the OP just happens to have a Stronglight 49 with a BCD of 50.4, Velo-Orange sells rings

Go to ebay.fr. Search velo>composant pieces de velo>roues libre. In January there are fewer listings and there is still no shortage of French threaded Regina cogs. Prices are quite reasonable. Shipping is what it is. If you want loose cogs or assembly of a custom cog the above suggestion of utilizing Yellow Jersey is a good bet. Remember that Atom cogs are essentially identical to Regina, merely manufactured in France.

I use Atom/Regina exclusively and in most cases only NOS. It is just not difficult or expensive. Keep your chain clean and lubed, if you are not a monster a freewheel lasts a long time.

Just wanted to mention largest Regina cog is 31. Atom went to 36. You are not likely to find more than a 28 but with patience they are there.

Buying used freewheels is sketchy. What looks like a clean cog that merely has a bit of polish is often a cog that engages and shifts poorly. If buying used be very picky.

WIth Regina the best product line was BX/Regina Extra/G.S. Corse which are all pretty much same. Oro cogs are also the same but cost much more because Eddy. All the later cogs as Syncro, America, CX are not quite as good as the 50s 60s70s standard. Maillard freewheels were quite good as well, and they are cheap, finding loose cogs is highly unlikely.

The front chain crank is a Campy Record, 52/42.

I found a French thread rear cluster, 14/24, which is real close to what I was looking for. It replaced the 13/17 that was on it, I got it pretty cheap and it arrived the other day. I have not ridden it yet, and it was the least expensive option, It was used, but appears to have lots of life left in it.

Thanks for all the comments. Now for the weather to break a little. Snow is expected tonight.

I have French thread 5-speed SunTour freewheel bodies that can be built up, but most of the smaller cogs I have are worn. Larger ones less so.

I recently bought a Peugeot with French thread Normandy high flange hubs, French threads. It came with a 24t 5 speed Atom freewheel. Lots of choices on Ebay for French thread freewheels. I found a 28t 6 speed Atom freewheel for $20. It went right on and works great. There are lots of them on Ebay. I just saw a 34t 5 speed French thread freewheel in the low $20s on Ebay a few days ago. Check it out, they are out there.
