Exactly the kind of Regina two-prong with worn notches that is primed to "asplode". Freewheel from the IED workshop? :eek:

Real Piece -O- Junk, eh?

Another thing I find that helps is using the "right" two prong tool. There were many different kinds of tools and some fit better than others.
Some were better quality than others too. I recently modified, slightly, a new Park (FR-2) two prong tool to fit an old Ciami FW. I was surprised at how "soft" the metal in the tool was.

I have never heard that?? Everything I have read shows the index rings were designed around the different Campy derailleurs and the number of speeds. Campy shows a spread sheet like below but they are primarily concerned with derailleur type, speeds and what chains work best with which freewheels; nothing about index rings being freewheel specific..

IED workshop? I dunno what that is. I had one of the guys at Recycled Cycles, down on Boat Street, remove it for me. I didn't look too closely at it, to see if he damaged it any, LOL, I was just happy he got it off. ;) It rides on an old '80s Campy Record hub now, and I like it. :thumb:

Regina called the Extra Synchro a "Campagnolo Designated Freewheel" and they showed the Campy trademark on the back <C>; although the difference in spelling with Campagnolo Syncro is a little confusing to me.

I have never had any trouble with a freewheel until a Regina 2 prong. I resist showing it because of the awful state of the prongs; after one side asploded (pealed off), I removed the front plate and dremeled some cutouts below the front plate and then put it back together. I was then able to remove it and it now resides on a 30 YO Mavic/NR backup wheel that will probably be a permanent wall hanging.

One Speed,

Great info on Regina and Campagnolo. Thanks for bringing some of us up to better speed.

That Chart confused everyone, all Those Freewheels had different Spacing. Even the smallest amount will make a huge difference when working with Syncro Systems.
Please keep in mind the 7 speed Syncro Derailleurs were all Slant Parallelogram. 8 speed syncro is a whole diffferent system. The system was flawed so much so that
Regina made a Special Freewheel to work with Syncro systems. Americas, CX's and other 7 speed Reginas will not index with Syncros, I know, I've tried.

I will post pictures tonight of my Super Mondia 7 speed SyncroII system with a Regina Syncro 90-S freewheel (blue insert) It shifts perfectly.

Timely topic for me. I'm currently building up a '62 and a '65 Paramount. I am planning to install Regina Extra freewheels on them.

Are these appropriate for these bikes or should they be using the G.S. Corse model?

I'm assuming that these bikes pre-date the Oro models.

I had a wheel with a Regina freewheel and I had a heck of a time removing it I went to a couple of bike shops who after looking at it said they could not remove it but one was able to sell me the Bicycle Research 2 pronged remover that fit the free wheel. After on various times trying to remove the freewheel I decided to stand on the wrench to try to free it and it worked. I then tried to take the cogs off the freewheel 1 and 2 came off fine but I could not get number 3 off in my attempt one of the whips broke the 24 tooth cog where it was drilled and so now my 5 speed Regina freewheel is toast.

Eric,

Really any 5 speed Regina on a '60s Paramount is appropriate. If it were me however, I'd stick with a model which uses the remover with splines not the two notched version.

Speaking of which, I'm currently transplanting the inner bodies with splines into outer bodies which used the two notches. Most of the cogs I have at the moment for these are the Oro variety.

Removing all the threaded cogs on a Regina or Atom 5 speed freewheels can be very challenging. I'd same my success rate is way below 50% and I have all the appropriate vises, chain whips, cog holders and 2-3 days of soaking in penetrating oil. If the middle cog comes off, there is a strong likely hood that the 4th cog will not budge. Or if the 3rd comes off the 4th is stuck.

If the third does come off, VAR made a vise adapter which fits on the threads of the 3rd cog. But even with it securely in place, this is no guarantee of success.

In the process of working with these Regina and Atom models, I have discovered that some of the cogs are interchangeable between brands. I've yet to build a Regina/Atom hybrid yet and give it a try. I should do this and see how they work.

Thanks for the advice but I think I've given up on this one though. It was on a campi hi-flange hub. I put a Suntour ultra six in its place

Thanks for your input Pastorbob.

Hah! All the ones that I have are the 2 notch variety, but the two that I'm going to use are NOS and I always make sure to use plenty of anti sieze compound on the interface threads.

Okay I'm still lost; except for the Chorus in the B position, none of the derailleurs in the Campagnolo charts are slant parallelograms; they are all inline parallelograms. Campy didn't switch to slant parallelograms until 1988 for Chorus and 1991 for Record and 1992 for Athena (+/- a year); the catalog I took the chart from was 1988..It is also my impression that by the time 7 speed freewheels were being made, most the freewheel makers were using the 5mm CtoC standard, it was the 8 speed freewheels/ shifters were Campy parted ways by staying with 5.0 spacing while Shimano/Suntour, and eventually SRAM and Sachs, went to 4.8mm.

The A and B position are for different range freewheels. I was commenting about 7 Speed Freewheels and Syncro II inserts. I know the confusion, it's terrible. No wonder Shimano SIS ruled in sales.

Yes, but the way the A and B worked, was to switch from a 5 deg slant parallelogram to a 30 deg slant parallelogram; in either mode it was the first slant parallelogram produced by Campagnolo (the 1st and 3rd generation Rallys had a drop parallelogram, but the slant was 0 deg).

Look at the different color index rings and notice the different spacing on the teeth, they all differ alot. I can tell you I've tried almost every one of those 7 speed freehwheels with the blue insert, they don't work. Then I read my Sutherlands,(should have done that first) notice they stated the only 2 freewheel combinations that work well.

I tried this on a Slant parallelogram Athena :

A note about freewheels on Campagnolo Record hubs without record stamp (pre 1963). The hub lock nut is wider, so the splined removal tool can't fit around it. And when I tried on a splined 5 speed freewheel from the 80s there was no room for a remover. So I had to remove the lock nut from the opposite side and pull the whole spindel out and then there was room for the freewheel remover.

Eric,

You live a dangerous life out there on the edge of a two prong world! ;)

Is that kinda like the green manalishi, with the 2-pronged crown? ;)

You got me wondering with this post, 1987. I have an old wheel down in the dungeon, a No Record stamp Record hub laced to a Nisi rim. I have two splined tools and they both fit over the old locknut, but one just barely. One tool , which as I remember is a Phil Wood tool, fit over the locknut quite easily. But I see what you mean about the older locknuts having a slightly wider diameter. I never tried this before because the bike/hub came with a two prong Caimi FW on it.

As I said before, the index rings are dependent on the geometry of different Campy derailleurs not freewheels. The Blue 7 speed index ring was for old style inline parallelogram derailleurs (except Chrous); it is doubtful your slant parallelogram Athena was not designed to work with any of the rings. I had a first generation Athena with it indexed fine with a blue index ring. I never tried Victory/Triomphe or the others on the chart but I suppose it would work just as well; you need to match the rings with derailleurs and the number of speeds of the freewheel. While I'm sure some freewheels worked better than others it was never contingent on the color of the index ring. A note this applies only to 6 and 7 speed freewheels, once you go to 8 speed all bets are off as Campy went their on way with their own freewheels.

Think tooth spacing then look at the chart......This is why Shimano SIS won the war here...

Okay, I know what you are trying to say. The reason Syncro didn't work well was because Campagnolo was trying to index their inline parallelogram derailleurs. #1 the different derailleurs had different cable pulls; the distance the derailleur moves when the cable is pulled. Because of this Campy had to create different index rings for different derailleurs; hence the different colors. This was not to match freewheels; if a 7 speed freewheel did not have 5mm spaced cogs, Syncro would simply not work (there was some experimentation here I'm sure but it was outside the design of Syncro. #2) Campy was trying to design a non-propitiatory (at least as far as freewheels went) design that was backwards compatible. As far as Shimano, it was no coincidence that their first workable index system was released a year after Suntour's Slant Parallelogram patent ran out and Shimano developed a top to bottom propitiatory system which was much added by their patent Centeron guide pulley; SIS. And it was not until Campagnolo went to a slant parallelogram rear derailleurs and their own cassette/ shifter propitiatory design that they had a competitive indexing design, which many (me included) believe to be superior to Shimano.
