A Colnago. Another similar example of disc wheel art to what I have been showing you....very cool. What I really like is the unique huge solid chain ring. I love how it looks, but could someone explain the purpose of it being like that? Interesting handlebars too. Nice period correct saddle too. This is a nice track bicycle.
Flywheel effect perhaps.

It may have been for an aero benefit.
Or to stop his leg getting oilly chain marks.
Could have had a 42 tooth under there and didn't want anyone to know he was weak.

It's not a solid chainring. It's a solid, round crankarm (or crankarm cover). Note that the disc is the same diameter as the crankarm length (i.e. the pedals are mounted to it) The chainring has a much small diameter based on the chain entry and exit points. Presumably it's to reduce the aerodynamic drag of the crankarms, in the same manner that disc wheels reduce the aerodynamic drag from spokes.

Sugino were doing something similar with their 75 CHCD cranks:

Clamont is the in-house marque of Clarence St Cyclery in Sydney, Australia. The high end and custom frames are built by Geoff Scott, who also builds frames under the Gefsco marque. He is a very highly regarded frame builder in this country and certainly provided frames for the Australian Institute of Sport (AIS.) He is still making frames to this day.

Love this bike 
Even ridable today in any race.
And Love those LA-wheels as well. Not sure that I'd crawl through glass for them, but it was one of the first Olympic Games I really wanted to follow on TV and all that. I was twelve, cant remember much of Moscow though (1980). I do remember seeing stuff from Lake Pacid and Sarajevo. And of course, every OG after that.
Thanks for posting stuff like this!

I will get some pics of a Graeme Obree TT bike. Superman position.
He delivered it to an lbs close to me in Ireland all the way from Scotland by bike and trailer.
He doesn't like to fly.
Sorry not Superman position but with the arms tucked up

Okay, I will say right out of the gate that I hate the handlebars with a passion. Other than that this is a bit interesting. One of the very few vintage orange disc wheels. Orange is very rare as a color for this use. Zipp might have made one. This rear disc wheel might have been painted later...not sure. It is a nice looking frame and setup and a bit different....Let me know what you think.

Old school fast
I gotta say markwesti, this is sooooo elegant, sleek, and smooth. Wow. If a black panther were a bicycle this would be it. This thing really shines. I love this bike. This thing looks FAST.....like a lean mean machine. Nothing superfluous here. It looks like it is about to hurdle through space. It reminds me of the Pinrarello Espada only in the sense that it looks like this bicycle would peddle itself.....like it would just glide sooooo smoothly......as if it would be effortless. It just has that look. You chose a bicycle that is also a work of art. I mean just look at this thing. I love how it is almost all black, I love how it shines, I like the beautiful MAVIC wheels...the carbon (I believe) texture on the rear one is excellent and the tire looks so minimal fitted to it which adds to the effect. I can't see the saddle too well from this angle (still a fantastic photo) so I will not comment on it. I do love the bullhorn like handlebars here. They did it right on this one. I hate it when regular handle bars or pista bars are used on lo pro bikes.....just my taste.
Big thumbs up on this one! Hoping for more of your superb choices to wow those that watch this thread. Thanks.

After all of the folks who'd worked on them had long retired, they were forgotten about and eventually thrown out a few years ago.
It still holds the world record for a hour on a velodome.

Air stream
Thank you for this amazing insider post! It must have been amazing to work on such a project and see it come to completion. The fact that it still holds the world record for a hour on a velodrome speaks for itself. It shows that all these modern bikes are not necessarily better than the vintage ones. It is often the case that those who deserve the kudos and our appreciation do not get it in this world. So in a very very small way, I would like to thank you and all those forgotten workers for making history. The bicycle is an amazing speed machine and a work of art. You are not forgotten here among true bicycle fans sir, nor are the others workers you have mentioned.
Please feel free to post any historical pictures you might have here on this thread if you so choose and it is to your benefit. Thank you.

Putting a fairing upfront or assuming the recumbent position indicates a lack of understanding of where the points of air resistance occur on a 30 mph bicycle and the best way to minimize the problem.
Kelly Johnson's design for the SR 71 engines understood the same problem . If you want to achieve astounding performance it is how you manage dead air striking your vehicle. More than half the SR 71 s engine size is simple ducting to manage the dead air prior to it entering the SR 71's jet engine.

The most interesting feature of this Level funny bike is the brakes, which are inside the fork blades and chainstays. I don't know if they're good at stopping but who cares? It's a TT bike.
