If she got to change a bit (was if after lap 1), howcome there was even a bike to change to? Odd for the UCI to leave a spare bike to race. Merely letting her finish the race is strange in itself. Would the same be true if EPO labeled vials were falling out of dad's pockets in front of the UCI bike checkers? Would she be allowed to finish the race, risking getting in the way of a deserving winner? It's one sketchy course...
I agree, we need a no-BS communiqué from UCI about how many bikes were seized. For all we know the one seized was the old detectable spare mid-race bike, while she takes an more stealthy e-bike into the starting area and to doping control. Heck, that's what I would do.
I've done some cross racing myself up to a few Mens Superprestiges. I would have been fine starting the race on a clean bike myself. The start is hectic, and pulling away from others or getting tangled up in the first corner, just not worth the risk of detecting. And the first lap was my only good lap anyway. I took some great scalps on first laps. If only cross races were shorter, much shorter...
I never raced with a spare bike actually and around that time (2001 or so) there were no bike checks anyway at SP races. No AD I got to notice either. I went back to the clubhouse a few times to make sure I was not randomly picked. They also did not check my tire width, 35mm was allowed at the time. Now with >33mm I have even less of a chance in cross, I'm big.
Yes there is mud in cross, but I wouldn't worrry too much about having an out of control spinner. Surely the system is cleverer than that? I would make up SOOOO much time with 150W extra on moments I need it. Asphalt to recover while making up lots of time. Deep sucky section, climbs. Give me a couple dozen seconds of 150W per lap and I would make them count like track seconds won on my vanished twin. If it makes the difference of making a climb and not making it, for an otherwise technically weak cross rider like myself it would make a huge difference. In MTB I was known for riding up what everyone else walked, so it would have been less suspect for me. Reality in cross though, I walked every little bumb. Crossers are maniacs. And in my time, I was probably one of the very few who was not juiced. The difference a little bit of EPO or e power would have made... Much more than the Joules on tap per lap. I'm sure it changes everything. Less time spent on hill and sucky sections, more recovery from a flat straight while also saving time.... Oh and if there is 50W of regenerative braking, that would make a bike much more manageable for me on technical descends. I suppose that only goes for powered rear wheels, not cranks.
