Man there are some crazy looking bikes on this thread.

Lattz

Well, that sounded like a bard's song in a Dungeons and Dragons campaign (Joe King here) plan! I guess one owns a Zunow on or outside these pages is envied by many and not without reasons.

As I see not even the original Bianchi Proto Crono is popping up on in the ads every week, and its "badge engineered" sibling must be even rarer.
I remember this bike, it is the absolute fav of Old Fireleg who wote, that it was only used in the team for one year. Back when he posted it, there was the road version for sale here in Germany for 14k EUR, guess this might be a tad more expensive especially with those Silva wheels, IF someone would give it away.

Well, I haven’t been thru every page but I happened upon this Rossin lugged Columbus at a yard sale while riding today. I put it on the c&v Appraisal Forum, But this is a good thread to ask about REHN wheel? Shimano600 SIS. Front rim looks toast. Estimate of value?

icemilkcoffee 

You didn’t ask the seller how much they want for it? Looks like a sweet rust free lo-pro in great condition!

^^^^Agreed, I think the evaluation of 250 was very low....frame alone would be worth that, that is if you could find one. What was wrong with the front wheel, cracked brake wear?
I hope that you at least got a contact number.
Best, Ben

The front wheel seemed to have damage to the road side of the rim, like it had been ridden without a tire.

Sorry I can't give more info. I only looked at it briefly, the seller is not a bicycle guy. There is a county dump not far from the seller and i'm guessing that's where it came from.

Wildwood,
OK, thanks,

Someone posted on bicycles stackexchange looking for info on this bike. Reynolds 753 tubing. Cinelli BB shell. Serial number on BB is DA followed by 4-digit number. Poster claimed that bike was used in the 1988 Olympics or a Commonwealth games around that time. Anyone have ideas what it might be?



Here is a link to the SE post:

I would make a guess and say it's a resprayed Rossin 4400 Cromor from '88. When I first saw it, wanted to qoute you my brother when I send him bike pics: "hope it's in your basement already". The model was originally available with Chorus and 105, and only in red/white, see pic below. I'm not familiar on Rossin prices over the pond, but in our neigbour, The Netherlands, a bare frame (with orig livery) was sold for ~EUR500. Rossin made lo pros even earlier, which are loosely similar but the 4400 has matching details to this (no head lug "R" cutout, pump peg)
Even if it is hardly anything more than a bare frame, here it would be in the 700-900 EUR range if I exclude the dreamers, who read who Mario Rossin or how famous/expensive the better known Futura became and would shamelessly ask ~1xxx even with SIS and broken wheel.
Regarding the rear wheel, There's a Danish TT guy, Daniel Rehn, I could imagine, this was his training wheel, maybe even his first bike, but this is really a romantic guess/tale.

P.S.: Actually the non-biker/Vespa/Classic car/nameyourpoison guys are the best to buy such things from.

ohh and the pics:


and the Dutch frame:

Wildwood 

No, not in my ownership. Really outside of my consideration or needs or desires. A 70 year old man riding a lo-pro Time Trailer might prove embarrassing. Besides, i’d have to Fix it and take it to Marymoor’s velodrome with a black Weinmann Delta brake on the front! holy shat, now I buy a bike around that quirky brake. At a time when I should be holding the headcount steady! IF it could be made to fit, looks small.

xiaoman1 

Lattz is correct....when I went back to look I think there's a Rossin panto on the rear stay.
I mentioned the 250 from another member was low, BTW there's is nothing wrong with a 70-year-old and a Lo-Pro....go buy it put it on the wall, unless you want to facilitate ..

Not a time trial, but the Need for Speed!

In my book, I would say it qualifies.....time, distance and speed...cool read!
Chainring seems small, and the Aero wheel is a little lacking in fineness but it at least has some cool drillium .
Best, Ben

Lattz

This is actually really cool. I envy the finesse and courage of such guys who build and ride such things, while sometimes I almost sh... my pants and feel like a superhero on a normal road bike on wet days just by managing to cross a diagonal tram track without licking the stone (again). While many details are oh-wow, I don't get the cantilever brakes.

Lattz

Thanks, had the pleasure to dig through a few thousand Rossin pics when I tried to research mine. I stand by my idea that REHN is the Danish guy as the sticker looks like that until something else does not prove it differently.
Anyway the wheel is nice looking with that big a55 hub flange seemingly without screws I like it.

Krono TT on Sunday riding in Long Beach near the ports.

Lattz

I afraid, we are outta luck here. This seems to be one of the hundreds of good, most likely British (but could be French or Australian) builders.

Whatever it is its a nicely shaped piece, that is sure and I personally do not like the "sprayed under LSD influence" paintjob (but respect that for others this is the wow factor), so I'm happy the owner gave mercy by painting it white. Fork is most likely not original (I think it is Columbus Air), although it is hardly a useful info.

Lattz

While generally I try to avoid (re)posting bikes, which are among the big classics (and fill majority of the thread's pages not without reason though), here I make an exception, as I have found them interesting because of the context.
I popped into a nice magazine copy from Japan most likely from '89 showing the bikes above JPY 1 million. Since it does not say a lot how much 1Mio was back then, the top shelf Bianchi X4 costed JPY~320k, and a new Toyota Supra ~3Mio. Of course the comparison is not fair, since these were (including the Bianchi) top shelf import goodies versus the Supra, but if anybody knows the '89er prices for top shelf Japanese bikes, let us know.
However it was, these bikes are out of this world in my opinion.

What material is that Bottecchia Kronostrada made out of? If that’s all steel that is an amazing amount of panel beating done to create that intricate aero frame.

Lattz

MY assumption is that the (plastic/kevlar/godknows) fairing is plastered/molded/younameit'ed onto the steel frame. For that seatstay-seat tube connection it would be tons of metal to weld/braze it, but who knows? Meanwhile found out, that my silly price comparison was really rough, as the article title only says "over 1Mio Yen" but this costed 2.3 Mio. well over one.

Lattz

Here's a nice modern steel, which has big-A55, fillet brazed fairings, however I still think, that this is not the case with the Crono Strada,

That is some insane sheet metal artistry with that Herten bike.

xiaoman1 

I remember seeing 2 lasers on the net that were crack at the lugs and wondered if in fact they were finished with metal brazing or if it was possible that a plastic filler could have been used to smooth out some of those clean lines.
Anyway a few more images for the group.
These may have already been posted but worth a look again, all business and just look fast while standing still!



New meaning to Lo-Pro!
Bertoni is still stalled .
Best, Ben

Oh yeah. But also it was not the painters first day of airbrushing I guess. It looks simple but nice.... looks simple.... sometimes i play with the idea to airbrush one of my frames then somerhing like this comes up and.... no frame would deserve a fate like that.
