Where do I post technical / parts questions for 90's Model Road Bikes (i.e. Campagnolo) ??

Please let me know.

Thanks!

Campagnolo is a component company, not a bicycle manufacturer. As well, bicycles can have been built up from a bare frame using parts chosen by the original owner. You have to look on a case by case basis. For example, I own a 2007 Look 595 which I built up myself using Campagnolo Record and Chorus components and a set of Campagnolo Shamal wheels. It is possible that no other Look 595 with the same component mix exists anywhere. This could easily be the same case for any 20+ year old bike which could easily have had components replaced or upgraded over the years. My Look has had the crankset replaced twice along with the chain, tires, and various cassettes

Right here, but on the Bicycle Mechanics sub-forum. This is the General Cycling Discussion sub-forum. Click on Bike Forums at the top of the page and you will get a list of all the sub-forums. Bicycle Mechanics is just a few down from the top.

90s bikes and components in general are discussed in the Classic and Vintage forum, along with older and (some) newer ones.

ALCJPHIL:

You are preaching to the choir. First, on my 1989 hand-made Ritchey Mountain Bike there is a non-native Sachs Aris Freewheel Sprocket(s) that is not performing well with the Mavic Hubs. I can't use my Rapid Fire button anymore because of a piece-meal set up (on my Ritchey). But let me cut to the chase, because I have an Ochsner Road Bike (Columbus Tubing) with Campagnolo drop-outs and Campagnolo Record Hubs and derailleur says Nuovo Record that I need help with. I want a Campagnolo Freewheel that is compatible with my setup because my pulley wheels are cracking because of non-native Suntour Freewheel that is on the bike (currently). I found a beautiful NOS Vintage Campagnolo 6 speeds alloy freewheel 13/21 and trying to see if it will work with Campagnolo Record Hubs and Nuovo Record Rear derailleur (but the price is ridiculously high and I want as many options as I can find because I don't want to pay $595 for that Campagnolo 6 speeds alloy freewheel 13/21 ! Please help!

I would post it in the Classic & Vintage subforum first. Maybe the Bicycle Mechanics.

I’m not sure about you request is for a Sachs Aris freewheel that is 6 or 7 speed. Also are you using Shimano Rapid Fire shifters with a Campagnolo RD. I’m not sure where the Mavic hub fits into this.

I’m running a Sachs Aris 7 speed freewheel with Shimano Rapid Fire and a Deore RD.

As far as pulley wheels, I’ve read Suntour wheels work. I know they are 10t bd. 9t. I’m not sure where the 6 speed Campy FW fits in the equation vs. a Suntour or Shimano UG. I thought all 6 speed FW’s were spaced the same.

...I don't doubt that your pulley wheels are cracking, but a Suntour freewheel is not the cause of it. New Record derailleurs are infamous for this problem, and they all crack eventually.


...unless your Suntour freewheel is worn on one or more of the cogs, just keep it and replace the pulley wheels on your rear derailleur. https://www.bikeforums.net/22098979-post21.html That Campagnolo freewheel would be a waste of money in your circumstances.

I always used Regina Extra freewheels on my old Campy bikes, they can still be found NIB if you look hard enough. There is an alloy version called the Extra Record, these are very light, and are much cheaper than original Campy alloy units.

Sorry for the confusion. I was talking about two different bikes that I own. I'm working on my Ochsner Road Bike currently and I'm trying to replace the Suntour Freewheel because when I shift to the top gear it cracks the pulley wheels on Campagnolo Nuovo Record derailleur. Thanks for your reply !

QUESTION: is the Regina Extra freewheel a commonly used freewheel for old Campagnolo bicycles ? I may going a little OCD on this topic (but I prefer NOS Parts that are period correct, like the nineties era). For example, the late 80's and and early 90's Ritchey and Gary Fisher Mountain Bikes were sold in the shops with Shimano XT / XTR derailleurs / shifters, etc.

KC007

Thanks for the tip on Regina Extra Freewheel ! I did the research and I like the Regina Extra (it is made in Italy) and will be a great upgrade for my Ochsner Road Bike. Thanks again !!!

Um, it was suggested you post your question to the proper forum instead of continuing it here. That was a very helpful suggestion, you'll get much better responses and info there.

I found a beautiful NOS Regina Freewheel Extra America 6 speed 13-14-15-16-17-18 * ISO Thread, do you think that will be compatible with my Campagnolo Nuovo Record Rear Hub?

I could not find any words on my hubs, except Campagnolo (but I know the hubs are either are from 70's or 80's Era)

Please help! AND Thank you everybody

I know you posted this here and Bicycle Mechanics, but if you want period correct, British threads (not sure of ISO implementation date), for your bike Classic & Vintage might be a good place to ask.

Make it short and simple, year make bike, components, appropriate period correct for the freewheel you want to use.

I’m guessing it will work if the threads match. If it is a wall hanger any NOS will work. If you plan on a l’eroica participation a rideable freewheel range might be a consideration.

As long as both the hub and freewheel have the same thread spec, it will work. English is 1.37" x 24tpi, 60° thread angle. ISO is 1.375" x 24tpi, 60° thread angle. Italian is 35mm x 24tpi, 55° thread angle. French is 35mm x 1mm, 60° thread angle. English/ISO and Italian are close enough to be compatible, but once you mount a mismatched part, best practice is not to go back and forth between and mismatched, as this reworks the thread angle each time and increases the chance of eventual failure.

Thread spec is marked on both the hub and freewheel, albeit sometimes in an arcane manner:

Question: Can I mount a Regina Extra America freewheel to this existing hub ?





(Older Post) I will upload a picture of my Rear Hub and take a closer look at branding. I think it says ' Campagnolo ' and that's it.

This is an interesting read, albeit only for C&V, on the British Standard Cycle (BSC) and ISO standard when it comes to freewheels.

Thanks JohnDThompson !

I guess I will bite the bullet ✹ 💥🔫 and remove the Suntour Sprockets.

Then I can take a closer look at the existing Campagnolo Hub.

One thing about vintage freewheels. I've used plenty of the two-notch freewheels in the past. I wouldn't go out of my way to get one now. Get one stuck, and they're a major pain.

The splined freewheels are much nicer.

If you do have a freewheel that uses a notched freewheel tool, then ALWAYS clamp the tool down tight to the hub with your QR before removing. I tend to do that with all freewheel and cassette tools out of practice.

As far as new vs old. The old freewheels seem to get pretty decent wear. However, the newer freewheels shift very nicely with the shift ramps and gates, and unfortunately seem to wear quicker.

It is easier to find new freewheels with 11T or 12T than vintage ones. But, it is much harder to find tight single step (corncob) gearing with the newer freewheels.

One may be able to adjust from 5 speed to 6 speed to 7 speed freewheels by changing the spacers on your hub and redishing the wheel.

Fredo76

How many mm between your rear dropouts? If 120mm, best to stick with 5-speed freewheels, and NOS Regina, etc. are indeed expensive. Beware of ebay sellers offering 5 cogs assembled on 6-speed bodies - they won't work with hubs made for 120mm dropouts, IME.

If you have 126mm dropout spacing, you can do 6-speed freewheels on older hubs and 7-speeds on newer ones.

Campagnolo did not make freewheels in the 120mm era, to my knowledge.

Hello 70'sSanO, I removed the Suntour Freewheel ... THERE IS NO GROOVE IN THE CAMPY HUB (thanks for the picture).

Question; Can I now forcefully move forward with Regina America Freewheel (it is Italian ?

KC007

Hello 70sSanO (a 2nd time).

Can I roll with a Regina Extra America (corrected) ? And would I want aluminum or not ?

Thanks, KC

70sSanO

JohnDThompson provided that info on the grooves and the pics.

Since I referenced John, hopefully he will respond.

KC007

I think I should go with 5 Speed Freewheel ❓ I will order Regina ... any Gary Fisher Mountain Bikes out there ❓

Hello Forum Members:

I have determined that I have 126mm dropout spacing, and I can do a 6-speed Regina (Made in Italy) freewheel.

I just need some advice because I don't want to return a purchased freewheel if it's incompatible.

Below is the link to one that I like on eBay and want to know if it will work:
