XRay is also somewhat privacy invasive to bike athletes, but not to "normal" people. The reason is that there is a huge competition on making bikes lighter while still being able to withstand the exact stress put on in in that one leg of the race. So they file off a little metal here, a little there, shorten some screws, etc. The secret is in how much you can take away in which places.

This can lead to bikes that are usable only for that one leg on that one day, after which you have to change the slightly deformed parts, because e.g. the braking downhill would kill your lighter, thinner, filed-down uphill tires.
