Technical Question : Ochsner - Campagnolo Freewheel upgrade
Hello Forum Members:
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 to research 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! Thanks!

I own several high-end vintage bikes. I also work as a mechanic at a bike co-op and I service many older bikes every week.
As far as for riding, you do not want an old Campagnolo freewheel, particularly one of the alloy models. They shift poorly, come in very limited cog combinations, and are hideously expensive. The alu cogs... they wear out in a fraction of time of any inexpensive steel freewheel.
For actual riding, you want a Shimano MF-TZ510 6-speed freewheel. This will cost you less than $20, and shift much better than any vintage freewheel ever made. Mate this with a Shimano HG-40 or IG-51 chain (both $15) for crisp and quiet shifting.
Derailleurs: replace your cracked jockey wheels. An old Suntour derailleur will shift better than any pre-1990 Campagnolo derailleur ever could. Actually a new $20 Shimano rear derailleur will shift better than any old Campagnolo or Suntour derailleur, but they are heavy and ugly as sin.
You want superior shifting and ergonomics? Then bite the cost bullet and retrofit your bike with brifters such as Ergopower. I'll be running 8-speed Campagnolo Record from about 1995 today, and mechanical shifting has not been improved on since.

Dave:
NOT ALL, but most of my setup is Campagnolo on the Ochsner (i.e., Cranks, derailleur, skewers, drop-outs on the frame - front & back etc.). I'm not going to put some ugly Shimano derailleur on my Ochsner, but I may settle
for a non-native Freewheel - I just have a budget on this project and tired of cracking pulleys on Nuovo Record derailleur. Perhaps I should look for a LOT of parts (i.e., Super Record derailleur \ Super Record freewheel or cassette).
Then the questions would be my Nuovo Record Cranks and if they would work with Super Record Freewheel / derailleur, etc ?? Please let me know your thoughts. Thanks!

Cracked pulleys on old Campagnolo derailleurs were very common no matter what freewheel you used. My solution back in the day was to use Huret pulleys. Not only did they have adjustable ball bearings, they also never cracked. Your problem is not the freewheel it is the pulleys

I have only 4' from me a Sachs Aris 6 cog freewheel, new in box, that I would sell you for far less than a Campy one. 13/24 tooth range, Vastly nicer in material grade and cool factor than any current Asian version. Still won't shift as slickly as the Asian ones with their shift gates and dedicated tooth shaping. But if you want to keep the bike Euro a nice freewheel to consider. Andy

Before you dismiss Sachs, you should be aware that Sachs was tied to Campagnolo spacing.
Standard 6 speed cog to cog spacing for nearly every freewheel is 5.5mm. Standard 7 speed is 5.0mm. But for 8 speed Sachs cog to cog spacing is 5.0mm; which is the same as Campagnolo. Shimano and SRAM are 4.8mm.
Sachs also offered their branded (Campagnolo) Ergo shifters; at least until SRAM acquired them.

John= I like to say that the Sachs FWs were everyone's 7 speed cog spacing (WRT an indexed system which the OP doesn't have) and offered an 8 cog option with the same spacing. They were the first brake lever located shifters I used and still do have some Sachs in service (although w/ Campy hoods and 9 cog index gear swapped for the OEM 8 cog one).
I'd love to find my box of Sachs FWS and cogs a home they will be appreciated at. Andy
