The original Olympics were competed in the nude. I'm not saying we need to go that far, but the Olympic committee has a standard pool for all the swimmers, and they could provide standard bikes for all the cyclists.
That's the same as standard course for all cyclist, which happens today.
The equivalence in swimming for organizer provided bikes is providing standard swim suits to all swimmers, that has not happened.
Another alternative would be if the transmission was provided by the officials and would be fitted to the bike and sealed before start but that could also spell problems.
In javelin and pole vaulting the athletes bring their own equipment. Has anyone ever cheated there? Interesting possibilities...
I'm sure some athletes would prefer a more ergonomic discus or shorter hurdles in track and field, maybe the gymnasts would like a slightly different geometry or spring characteristic for the bars or vault, but they don't get that choice.
I understand that people need differently sized bikes because they have different heights and slightly different ratios of leg/torso/arm lengths, but I can easily imagine having three or four standardized frames with adjustable seatposts, seat rails, and stem length, with a selection of various length stems and cranks. Just put the same wheels, the same mech, the same bars, and everything on every bike and see which rider is fastest. Call it an "Olympic bike".
The Olympics are a one-off that happens infrequently, but still draws from the same set of world-class riders as the rest of the racing season (a season that happens ever year, and contains far more important events).
There's zero chance what you suggest will ever take root.
I’ve always wanted to represent my country in the olympics, and maybe one day I will on a standard Olympics bicycle!
Anectdotal evidence to support this.
Specialized had pretty high end helemets for cyclists, but for some reason, the Italian riders would also complain about them. They finally got some of the Tour riders together to try and figure out what they could to do solve this issue.
To me, it was pretty funny. They complained that the straps that came down on both sides would lay on their face and cause tan lines. I'm not kidding, this was a major issue and Specialized changed the straps so they were embedded in a way that hung off the riders face so it wouldn't cause tan lines.
You had to show people how cool it was, it was such a minor thing, but to these guys, it was a big enough problem they actually solved and then put into their high end helmets.
I ride a lot, and I barely have them, because sunscreen exists and I don't want cancer.
Some brands fit, but not comfortably. Some brands (POC, for example), just don't fit my head at all.
What happened was cyclists lost interest in the hour record because the bike became too dissimilar to the bikes they were riding professionally.
After a new rules for modern bikes were introduced for the hour record, interest was renewed in the discipline.
For something like the Olympics which is a one day road race or individual time trial, I think the current UCI rules for those bikes are fine. Everyone is on roughly competitive bikes. Marketing aside, I don’t think anyone really thinks the top Specialized bike is better than Canyon or Cervelo or Trek or whatever.
