I have had a real passion for Campagnolo since the late 1970's and I'm still discovering little things about the company all the time and this Forum is a great place to be to find out all sorts of interesting stuff. I think it was the late '80's when I discovered the Portacatena system to derail the chain, and, back then, things were more plentiful so I chased-up my first Portacatena components along with an appropriate frame.

You have a pretty impressive list of bikes and your Bob Jackson really caught my attention and the famous Tom Kellogg certainly stands out as well. Anything LeMond is something I would cherish as Greg was such a big influence in cycling. Best wishes.

When it comes to corn cob freewheels, I harken to the wise words from John Madden: "I couldn't do that when I could do that."

I had a Regina Oro 13-18 6v on my criterium sew-ups.
That's probably why I never won anything... needed a 12t.

Look at that - hardly bigger than the small flange hub.

The Regina Titanio "Super Star" freewheel must be one of the rarest. Regina offered the Titanio in two versions, this is the all titanium version. Even the body is Ti! The Campagnolo freewheel is pretty exotic, if not as rare as the Titanio. Jim Merz

Great set-up. Love the chain. The freewheel and chain combo is top self. It must be on a well loved bike?

This was obviously before genetic modification of our crops went into effect. Just look at how plump and full those corn kernels were 120 years ago!

If Im reading this right, it was possible to build an 11-16t corncob on the old Dura-Ace EX/AX cassette hubs. My knees hurt just typing that.

Good to know. I have a Dura-Ace with 12 low that plays nicely with Campy NR setup.

This is true, or an 11-17, 7-speed UG corncob cassette variation. But only on the Dura Ace UG freehubs, not the 600 freehubs.

While I haven't tried, my guess is that by using either 9 or 10-speed HG spacers, an 11-18, 8-speed, could also be assembled on these 126mm spaced hubs.

And for years, I rode triples (including the first 15 years on the Mooney) with 52 (or 53) -42-28 X 13-19 5-speed. First year of racing, I just screwed in the inside FD for the open races.

Edit: My current 9-speed has the Campy cassette. Lots of gear choices, I often run it 12, 14-19, 21, 23 so an almost straight block. (12, 14 because I hardly need the big gears except Portland and Oregon have quite a few big descents and I like the big gears to quiet the bike.)
Speeds at 80 to 100 rpm for this 53/42 and 13-19. (The triple makes this a lot more practical.)
28 in red, 42 in black, 53 in blue.

That's reasonable shift spacing in the range, but steep hills must have been a very low cadence with just two chainrings. Low gear with the 42 at 35 rpm is still 6 mph.
What about sprinting at the end of a race? 53-13 at 120 rpm is about 38 mph.






~~~~~~~~~~~~~~~~~~~

When I was riding fast-for-me club rides, I needed close shifts at 18-25 mph to try to hang on. And there were hills too.

So I made a Shimano 11 speed combo cassette from a Junior Racing 14-28 and an 11-32. The two carriers for the 5 largest cogs are from the 11-32, shown in red.
14-15-16-17-18-19-22 25 28 32 with a 34/50 front.

It worked great at those higher speeds, but shifts at lower speeds in the 34 ring at 10 mph, etc, were too close together. I'd shift 2 or 3 cogs at a time then. And I'd be coasting downhill at speeds higher than about 28-29 mph.

True vintage corncob pic. Pic taken around 1979 of my Assenmacher. Keen-eyed viewers will note the tied&soldered spokes on the non-drive side, the drilled chain, the gold corncob, the Pino Morroni titanium skewers, and the gold-plated cable housing

I know, forgive me. I do have a SunTour corn cob FW but no photo, but frankly when I heard show us your corn cobb, I thought of this water tower I grew up a few blocks from in Rochester, MN. It's at what was once Libby's produce processing plant, dating back to 1933 under the owners name of the time. The plant was recently torn down, so I read, but the wonderful tower remains. It's classic, it's vintage and it functions as intended.

Cyclo Pans 13-18 6 speed. This was my go-to freewheel that was always on my race wheels. A road race on Saturday would usually mean a 13-21, maybe a 24 if it was really hard. Then spin off the smallest cogs and change to a straight block if there was a Sunday criterium.



Regina Extra 12-20 6 speed



Sun Tour Pro Compe 5 speed 15-19 from my old commuter bike
