That is a beautiful bicycle. Thanks for sharing. PM sent.

that is an unusual bike, but why no pedals?

OEM pedal specs became a big issue on high end bicycles in the mid-1980s, when clipless systems were introduced. There were so many incompatible pedal systems introduced over a relatively short period that it was impossible to predict what a customer might prefer. Customers were reluctant to pay for a pedal system they didn't want and, given the high price of a clipless shoe and pedal system, often transferred their preferred pedals from their old bicycle. As a result, shops were discounting bicycles and being stuck with a lot of quill pedals that they had removed from bicycles. Consequently, shops started ordering bicycles without pedals, which led to an industry trend to supply higher end bicycles without pedals.

OK, but this is a "gentleman" bike by the set up, undoubtedly used with street shoes. Wide metal touring pedals, or even rubber adorned pedals.
My beef is partly that so many bikes are now sold without, bikes that were from the clip and strap era... I get race bikes from the later 80's onward have a bit of an excuse.

There would been literally thousands of bicycles that would have been updated to clipless after they hit the market. Performance oriented cyclists were only to happy to discard their uncomfortable toe clips and straps. I had probably a couple dozen cases of this among cyclists that I coached in the late 1980s. Frugal ones just coming into the sport would buy a used bicycle that was a few years old and update it clipless and indexing and still save significant money over a new bicycle. When these updated bicycles got sold, they tended to remove the clipless pedals.

Pedals are also a very high damage item on bicycles. Being a low and protruding point of the bicycle, they get banged around a lot and suffer a lot in wet weather. They're also one of the components least likely to be serviced. They're almost treated like consumables. Think of how many pedals you seen that have bent axles, are rusty, scraped and missing dust caps. Pedals are often in worse shape than the rest of the bicycle. Many owners find it easier to get rid of the offending part and let the new owner deal with it, than getting replacements.

We must agree to disagree, that Colnago Gentleman is in terrific shape. If it was set up without fenders and had drop bars, you are correct, even more so if it had otherwise shown the scars of use/war and even minimal neglect.

Yes, it took me a while to warm up to the 1st gen Chorus crankset aesthetics, with its bent looking arms and strange puckered center bolt section, but after a whileI appreciated the aero concept that was behind its design. If you look at the crankset from the front of the bike, you will see how minimal the aero profile is of the crankset. All the unusual details suddenly makes sense when you see it from that perspective.
I really think that the 1st gen Chorus gruppo was engineered much better (Except for the Synchro shifters) than the higher model C Record Gruppo was. It all just generally worked better than the rest of the Campy line of that time, and was certainly easier to set up, as long............. as you forego their Synchro shifter system, or just set it permanently on friction mode......

Thank you. that button was exactly the issue. I am not sure that I would have ever noticed it.

Good luck with the repairs. I have given up trying to get the grease out of the deeper crevices, they should be cleaner by the weekend.

Interesting bosses on those bikes, Seems more complex than adding eyelets near the dropouts.

Here is another look at the Colnago Gentleman. Those panniers are fantastic! The spec sheet says Super frameset. Wonder if some of the frames meant for this build actually got used to build race bikes, such as mine? And repechage This one has pedals!

no, those pivots on the end of the lateral cage are only Chorus. One of Campy’s attempts to circumvent the SunTour patent on slant parallelograms.

Oddly, one of my favorite cranks as far as lines...subtly more complex in the curvature. I have some that are waiting for good use.

Yes, thank for reminding me of my error. I was just starting to feel normal again. *sniff*

Campagnolo didn't need to circumvent the Maeda slant parallelgram patent because it had expired a few years earlier. However, Campagnolo had a reputation as an innovator and just adopting the slant paralleogram would tarnish their reputation. Instead, in 1988 they introduced three different derailleur designs. First was Croce d'Aune with its Twin Axle System, next was Chorus with it's Dual Mode System and finally came Athena with it's Lateral Operating System. My impression was that Camapgnolo had lost their way and was randomly throwing darts to see what would stick. Eventually they realized that the traditional slant parallelogram was the best approach and they adopted it for 1991.

I can't argue with that. In any case the Campy derailleur with the pivots at the ends of the transverse paralellograms, enabling them to imitate the real slant parallellogram designs, was implemented in the Chorus line-up, not the Record.
