Sadly the old Dutch trick of using a half-broken 30 year old bike as your 'stationsfiets' ('train station bike') won't work well for high-performance, I'm afraid
But yeah, that's awful. I'm sure the data to recreate them is all there, so that's no problem, but other than emotional value those things are monstrously expensive..twenty bikes, hundreds of thousands of euros in total costs.
Makes you wonder, considering the amount of times these things happen, maybe they should bring at least their 'main' bike to the hotel room or something..
