I have a few different FW's and derailleurs that I've used as well as other parts I'd like to replace with the originals or close to originals. Anyone have a list or link? -BG   Posted: Mon Apr 08, 2013 12:39 pm vanhelmont Joined: 11 Dec 2007 Posts: 242 Location: Florida Here's the specs from the 1970 catalog, I'm pretty sure they are unchanged for several years after that. http://www.gitaneusa.com/images/catalog/1970_pg11.jpg Specs...   Posted: Mon Apr 08, 2013 4:51 pm Beegee225 Joined: 20 May 2011 Posts: 28 Location: Hightstown, NJ Thanks for the specs... It lists the rear cog teeth, but doesn't list the maker... I have a tight ratio Regina that I think went on it. Do you think that's correct? Nice seeing the color variations on that, too. BG 71 SC Freewheels   Posted: Mon Apr 08, 2013 8:32 pm verktyg Joined: 14 Jan 2007 Posts: 2814 Location: SF Bay Area Gitane used Atom freewheels on most of their early 70s Super Corsas and Tour de France bikes. Usually 14-26T 5 speed but sometimes 14-24. On occasion you might find a Normandy (lower end Atom) on some mid 70s TdFs. Those bikes came with a wide variety of sewup brands. Never saw any Dunlop tires on any Gitanes. They had Mavic tubular rims. One other thing, SCs came with high or large flange Campagnolo hubs. TdFs originally came with Normandy Luxe Competition high flange hubs until maybe 1970 or 71. After that they started using Campagnolo Nuovo Tipo hubs. Campy high flange Nuovo Tipo hubs.

I'll dig around... The Atom sounds familiar. Atom freewheel with rare silver sprockets. These came with internal splines and were generally easier to remove that some of the other brands. Italian made Regina freewheels eventually changed from 2 removal notches to this same style spline. IMLTHO Atoms freewheels were far better quality than Regina freewheels. Normandy freewheel with large removal spline. _________________ Chas.

Can't find another cluster that looks like it fit. Still have to clean it up AND take it off the Phil Wood... Wonder if I should try to look for an Atom replacement...

The early 70s Gitanes had metric (French) treaded freewheels. The Regina most likely (99%) has British or Italian threads. You may have a problem removing the Regina FW from the Phil Wood hub. _________________ Chas.

I had taken it off the Campy hi flangers a while ago and placed it on the Phils for a different wheelset. It may be welded on by now for all I know... What's your technique for getting that off? -BG Regina FW off!   Posted: Wed Apr 10, 2013 5:21 pm Beegee225 Joined: 20 May 2011 Posts: 28 Location: Hightstown, NJ Just took off the Regina on the first try... (and a little liquid wrench before trying). Used a Cyclo two-prong that seemed to fit snug with the skewers close in. Can't believe that... Must have been on there a long time and several hundred miles ago... Now on to the rest of the parts. I'm looking at replacing the current modified bullhorn bars with a Cinelli stem and road bars.... It won't be kosher, I think the original was a Pivo? like the stem, but I don't know as nice looking alternates as the Cinelli. Lucky   Posted: Wed Apr 10, 2013 7:10 pm verktyg Joined: 14 Jan 2007 Posts: 2814 Location: SF Bay Area You're lucky it came off easily... The Phil Wood Hub has English/British/BSC threads. Italian freewheel threads are slightly larger than BSC threads. Both are larger than French/Metric treads. French 34.7mm x 1mm (1.366" x 25.4 TPI) BSC 1.370" x 24 TPI (34.8mm x 1.058mm) Italian 35mm x 24 TPI (1.378" x 24 TPI) Your Campy hub is most likely French threaded. Italian and BSC freewheels will interchange but putting them on and off more than 1 or 2 times will damage the hub threads. Both Italian and BSC freewheels can be forced onto a French threaded hub but they will damage the threads because the thread pitch is different. I've seen cases where one of those freewheels has broken free of the threads and spun loose. I would try to find a French threaded freewheel. Check eBay. There are no bicycle component correctness police! In the 1970s it was common place to install Cinelli or 3TTT bars and stems on Gitane TdF and Super Corsas. Brooks Pros or B17s were the saddle of choice on TdFs. If someone rode the bike a lot, they may have installed Campagnolo Nuovo Record derailleurs if they could afford them. If not, they used Suntour parts. If you where putting together a custom built French bike like a Rene Herse or Singer for concourse purposes (a show bike or wall hanger) then having period correct components would be important. Same thing with high end British and Italian bikes. Have you ridden your bike much? It looks to have good usable components which probably perform better than the original parts. You could invest hundreds of dollars into your bike and it would still be worth ~$500-$600. _________________ Chas.

It was a "barn bike" that had been in storage for ~20 years. I invested maybe an additional $150 in it plus hours of elbow grease to clean and polish everything. Today it's probably worth ~500-$600 to the right buyer. I built it up to ride, not make a profit on it. How it looked when I bought it: How it looks now: Remember, the French built bikes to ride, not look at! _________________ Chas.

What I'm trying to figure out is that the Regina, (French mfgr.?) originally came off the Campy, (French threads...) Later, I had a different wheel set put together with wider rims and Phil Hubs, (BR or Ital threads) and used a Sugino (? threads) for touring. I took off the Suginos and placed the Regina on the touring PhilW. Now, that's off and about to go back onto the original Campy one where it came from. Not sure whether the PhilW is "rethreaded" now and the Campy is, or isn't about to be... And, If I look for an French Atom, would I be rethreading the Campy...? Scary, since these things are vintage AND aluminum alloy. Maybe I just need to get a thread gauge and confirm who's on first... BTW, the Regina was a 14-22 cluster... maybe it was the brass "gold" G.S. Oro plating throughout that gave it the protection against welding itself into the PW hub...? You mentioned applying a locking thread protectant in an earlier thread? Wait a minute...   Posted: Thu Apr 11, 2013 6:37 am Beegee225 Joined: 20 May 2011 Posts: 28 Location: Hightstown, NJ Guess I have to review all the posts.... The Regina is probably Br or Italian.... the Phil Wood is probably BR... and the Campy is probably Italian, so I might be damaging the Campy because it'll be the second time it's been on it. Still. the Campy may be changed already, and not suitable for an Atom... I think I got that right...

In other words, most French cyclists preferred bikes equipped with French components. Regina freewheels were probably banned in France! Sheldon Brown (RIP): "Regina was a noted Italian manufacturer of freewheels and chains up through the early '90s. The Regina "Oro" ("Gold") chains and freewheels were the standard for high-end racing bikes in the 1970s and into the early '80s but Regina lost ground to the better shifting French Sedisport chains and better shifting Japanese freewheels from Sun Tour and Shimano. The coup-de-grace for Regina was Shimano's S.I.S. index shifting system. The word "Regina" means"Queen" in Latin." Only the sprockets on the gold colored Regina Oro freewheels were brass coated (oro means gold). Aside from some corrosion resistance (???) the brass coating was merely decorative. The internals of Oro freewheels were much better made than standard Regina freewheels but not worth 3-4 times additional cost over an Atom freewheel. Regina Oro $19-$30, Atom $6-$8... Regina Oro chains sold for $19-$30 too! BTW, The bottom end Suntour freewheels were better quality than either Atom or Regina freewheels. Are the Campy hubs large or small flange, Nuovo Tipo or Record? See pictures above. Gitane Tour de France bikes came with large flange Nuovo Tipo hubs from about 1971 through 1975. If the wheels are original to the bike then the rear hub most likely has French threads. French thread Campy hubs would have only come on French bikes. _________________ Chas.
