If I recall properly, after the ww2 on the races some tubular had a layer sew OVER the rim to ensure in case of problem with the tire, it would remain “more” on the rim... quite brutal... but inline with the reinforcement you see on the saddle or below the bar.

I'd like to see UCI significantly relaxing technical regulations for TT bikes. That could bring some fun back.

New Ceepo Shadow-R. Don't think it's UCI certified.

Their other bikes are more normal but still interesting - they look exciting like the bikes of my teens before the UCI clamped down on that sort of thing.

I'm left handed, if that matters.

Well that’s the ultimate solution for reduced frontal area.
Pinarello had a prototype made for Indurain but it handled like crap at high speed.

That was quite of an issue cause the other option was a simple straight fork that was not really that aero. Mike burrow estimated that it cost him more than 1km compared to something like the single leg fork used by Obree.

I have somewhere another picture of another prototype using similar design.

I remember a time trial bike used by the german national team, with a radical drop frame and "split" tri bars where the hands and ellbows were shoulderwide apart. Can't manage to source any photos anywherte though. I think they became wolrd champions in the 100km time trial on it, if my memory serves me well

You must be thinking in FES
Image
From my phone archives I only have the track frame but very similar shape was used on the 100km TT for 88gold medal. The 24” wheel was key to be closer from the rider in front of you. Ullrich used similar frame design in 98-99 (?)... so imagine riding this 10 years earlier, full carbon frame and bar!
ImageImage
FES is quite unique, started as RDA tech sport center in the 60s (literally it means something like “sport equipment research and development center” and build a dozen of frame absolutely uniques and never really commercialised. Image
I saw most of them on tracks... but this kind of hybrid, Lotus rear (single leg) with apparently a short front I discover it this morning! Image

Hi C36,

Thanks for those FES photos, really amazing bikes! In those days it seemed FES was willing to make any kind of bike you could imagine. :-)

But Dan512, your comment made me think it wasn't FES but something more modern. Maybe the team time trial at Eindhoven? I couldn't find anything in a quick search, but I also remember the elbows and hands both being shoulder width. At the time they said it was something to do with aerodynamics in team formation, wouldn't necessarily work in individual time trials. Maybe the Dutch (or Rabobank) team? Does this sound familiar to you?

Cheers,
Damon

Actually the first tyres developed for bicycles were like that!

If more recent then I don’t know what Dan was referring to! Curious to see it!

For FES it’s tough to track what they really did since there was no real commercial targets. Even on this frame they did so many variation (without a clue what were they designed for)
