Replacement Freewheel suggestions
Hi All,
I currently have a 13-19 6 speed Regina Extra freewheel on my '85 Atala Professionisti. I was able to handle these gears about 30 to 20 years ago. What replacement freewheel would you guys suggest that would give me 28 low? I have a Campy C-Record rear derailleur and a Campy C-record rear hub (english thread). I've seen many Shimano freewheels online, but I'm not sure if they are only meant for Mountain bikes. Has anyone here recently changed their vintage freewheel? I don't want to buy a NOS freewheel that's going to cost me $200 bucks.

There isn't any difference between mountain and road spacing on freewheels. As long as the derailleur can handle the largest cog and take up the excess chain, you should be able to use any freewheel.

Check out Sun Race freewheels. I've installed a number of 5 speeds with good performance. I even used a MTB 28T on an old Dilecta touring bike to get some needed lower gearing. A recent Sun Race BB was a very good buy at $15.99 as well.

Here's a Similar post started the other day. Lots of good advice with mentions of a few specific models and eBay sellers.

I am using a Shimano 6 speed, 14/28, that I purchase on ebay a few months ago. Seller was kingpaguy. Still quite a few on ebay but not sure if any for kingpaguy. Amazon has a large selection of new free wheels, including Sunrace.

@crank_addict swears by the Sachs/Maillard LY-92/94/96 freewheels. They are thick as thieves on eBay (both 7sp and 8sp, make sure you pay attention). I've not yet pulled the trigger on one, but will eventually. Just picking through a quick search, I see big cogs of 20, 21, 24, 28, 30, and 32. Note though that the 28, 30, and 32 examples I saw were 8sp. You might need a little patience to find a 7sp with a 28T big cog.
OTOH, Boulder Bike has some new 8-speed 13-28 and 12-30 Sachs freewheels:
Sachs Aris 8sp 13-28 freewheel - you can convert to useful 15-28 7sp
Sachs 12-30 8sp - you can convert to 7sp
According to the description, you can remove the small cog and go with the 7sp remnant. Mike Kone knows what he's talking about, so that might be another option.

Another angle on this: what crank do you use, and what top gear do you realistically need at this point? If you currently have a 52/42 double, switching to a 50/34 compact would extend the low range of your existing freewheel quite a bit, and then a change to a 13-24 freewheel would get you lower than an X-28 freewheel would on your old crank alone.

chances are you have an itailan threaded hub. per sheldon you can put an english threaded freewheel on with the caveats.... no going back to italian after putting british on and this is not advised for tandems and strong riders.
I have done this with no problem
Also you may or may not be able to make the campy work with 28, IIRC from posts I have read it is a bit hit or miss
also check out @PastorBobinnh his freewheel spa may have some available

My personal preference for vintage road bikes with a Campagnolo drivetrain is a Shimano indexing compatible FW with a modern chain. This is not period correct, but does wonders for the shifting. The better quality ones are getting difficult to find, Especially the 13-28 six speeds.

I also use modern Shimano stainless cables and pulley wheels on the RD. Shifts like a charm.
