Is it possible the ones with the script are team issued cranks?

Lattz

Is it possible that those scripts are just cut vinyl stickers on the normal (its not normal in any sense) chainring? As crank+ring is available on ebay for 300 as well in good shape 800 is a bargain for the stickers.... somehow the text is not really curvy.. but maybe its my eyes only. But we know that on Shimano Sugino Stronglight these big texts were default...and look awesome... while the awesome look is granted here as well I have a feeling that those stickers did not come from Vicenza.

On the subject of solid chainrings:

No Campy script on this one either, but it's pretty wild.

I guess most of us would need more time to spend here . Here is an ISUU link to the whitepaper, although it worth to search for it, as mine was a downloadable pdf in good quality i fail to find at the moment. I guess in the dawn of the modern aerodynamics in cycling, companies had not too many options to work with someone with experience besides Ferrari and some universities. This was also a big difference in the Western world vs. Eastern Block race in my opinion. While in the West a commercial bike company had to pay serious money for a commerial car company to get access to knowledge and wind tunnel, etc.... while in the Soviet Union everything being state controlled, if the order was to build the best bikes to win olympics, the state
A: bought the best ones available (see red teams on Lasers, Rossin CXs)
B. gave order to build the best one and all other industries are there to help even across countries within the block (see Takhion, but also others - I'll come to this in a separate post).

I've seen them after the post, because my curiosity sensors blew up upon this one, but for sure, now i do not find them. There are definitely 2 pairs for ~500 (which is still super compared to 1200)
here and here but I'm going to keep searching for the 3xx one as well (I hope, its not that I didn't overlook the Giant Stronglight text on that one, since that's 3xx the same what was on the chrome Battaglin earlier).

Lattz

I surrender. Looks like those who learn to read at an early stage forget to read earlier as well. I did not notice the FOR Campagnolo text... so these are not real either. So far only the posted by @malcala622 is the only one which has brev Campagnolo stamped on it, not sure if this matters though. Btw at the same seller theres a single chainring for 2xx. Still expensive especially if its not THE thing.

These are all great lookers!

I can't know positively, however these appear to be recreations. Someone has hired a talented machinist to make new chainrings and attached them to vintage crank arms. With today's computer controlled machining this would not be too difficult or time consuming to do and these people have obviously found a route to make it profitable for themselves.

Lattz

Every single one of them! Including the ones you posted after this.
Besides many of these are in my top list this time the Oscar goes to Vitus as i also planned to post ir together with Alans as none of them are famous for their lo-pros.

OK, a bunch of trackies and pursuits that stand out from the crowds. Paint on the Rossin is simple but I really like the colour combination.

Yes, like those Assos cranksets, however these six arm Colonago cranksets have to be my classic favourite. And on the crank sets, have you priced what big chain rings are selling for these days? I still do a bunch of track racing and the trend over the last few years is to go too bigger and bigger chain rings and cogs in the interest of reducing friction. Along with sprinters getting stronger and stronger, spending more time on strength development in the weight room for power and the ability to push bigger gears. Check the price alone for a 55+ tooth good quality 1/8 chain ring, you are looking at $175.00+ just for the ring and that price has gone up almost 75% on eBay in the last year or so. Most dedicated trackes will carry rings from a 48 through 54, it gets expensive.
What I am trying to say is I don't really think what these guys are asking for their recreations is so far out of line with the current market equipment.

Also the handle bar treatment on the Bazou bicycle are track grips made by Strong-V named Mix, similar to golf grips, not tape.

Pictures, Crankset and my current track bike, yea, old man, I am 66.

The Colnago six arm crankset looks super nice. Not sure about the price on the chain rings. Maybe someone in the forums can enlighten us. Thanks for the tip and correction on the bar grips. I will have to look those up. Keep riding....looks like your kicking ass and having a helluva time doing it.
I leave this up out of respect for this gentleman.

Another thread, with a discussion on truss forks, reminded me of a very interesting TOC TT bicycle. Attached are two photos of Harry 'Goss' Green on a bicycle with which he dominanted the British TT scene. During the time period of 1899-1909, he set 15 TT records, many of which were unbroken for decades. His reign as record holder for the London to Liverpool course (203 miles), stood for 29 years!

The bicycle is a Dursley-Pederen and is interesting for a several aspects. Most notably, the Pedersen design uses a truss style fork and frame consisting of small diameter tubes. While more complicated and expensive to manufacture, it provided a higher strength to weight ratio, resulting in a strong, rigid but light frame. The racing models had claimed weights of only 17 to 19 lbs. A hammock style saddle provided some cushioning, to compensate for the stiff frame on the rougher roads of the era. The saddle was supported by guy wires strung between the head tube and seat tubes. To keep the saddle level, the frame resorted to an extended head tube.

Goss also installed a Bricknell Auxilliary Hand Drive that powered the front wheel. The linkage was similar to that of a steam locomotive. The handlebar pivoted at the centre, allowing the grips to be pumped up and down. This action moved a driving rod attached to the handlebar, just inside of the right grip. The other end of the driving rod was attached eccentrically to a crown gear, so that the pumping of the handlebars turned the crown gear. The crown gear engaged a right angle pinion gear on the front hub, to drive the front wheel. I'm not sure but I'm assuming that the pinion gear was a freewheel, so that Goss could activate the hand drive only when required.

BF isn't allowing me to post photos at this time. Will try again, later

A fellow member over on the Paceline that still races his. A portion of his story is here https://forums.thepaceline.net/showt...dersen&page=10

"Thanks, my riding this bike started out as an experiment, to see how (with training efforts) I could do on it as if it was a modern bike.
I did hillclimbs, criteriums, MTB then settled on CX as my preferred discipline.
So the "platted cord" (made from a leather shoelace) serves as a grab-handle for sailing over the barriers. Photos below showing barrier hops before and after I added the handle. The machine got one of it's nicknames for my style of "flying" or airing the bike out keeping my hands on the grips (1st photo).

The sections of chain are a means of adjusting the length of the "tension strut" cables and thus changing the saddle height. There were parts missing when I bought it sourced from an abandoned storage unit.

Notice also the front brake pad tethers, intended to support braking loads directly, isolated from the pivots for better braking (done out of necessity after my first mtb race in wet conditions)."

Viewed these today, not favourites, not much too beautiful about them, can't all be pretty faces, however they are different and someone was trying to go fast.

P.S. There was a set of the Strong-V Mix grips with a black base colour in the Cherubim video, did you catch them TTfan?

...you actually consider a plastic headset to be a workable compromise. Well nylon really, and it only had to last for an hour, so it was probably over engineered for this bikes purpose. In the words of the great Colin Chapman "to make a car lighter, keep taking things off until it breaks... then put the last thing you took off back" The builder of this bike definitely thought the same way.










The full gallery is here, lots of other super-light craziness to be seen on this one, and that Gios Blue...

That's really interesting... I think I may have the road version of that frame (sort of). I Will post tonight..

Thanks to VintageTTfan for a great thread. I check in every few days for my dose of eye candy.
This thread has got me itching to build a way-out TT bike, which is about the most useless thing i could add to my garage at this time, but it'd be sooo coool, lol.
Thought I'd contribute something I turned up on my own:



Purportedly an 80's Nishiki; It's a little rough, and not complete, but it is available for sale. (local CL)
I might be tempted to buy it, but the seller is really, really proud of some of the old bikes he's got on his lot.
