Well if you riding on your normal UK trail bike it will not be as beefee as a DH bike, so a trail bike in t’alps may break a bit more easy than a DH bike, if you are using same trails, yes?
Plus ridign all day in heat on harder trail makes yu more tired so you take poor line choices, ride a bit less finnessy whatever.
Last year I smashed a rim, Del totalled a wheel, Jims crank snapped, Cockey-wide-boy-geezers we were with had some bits break iirc (including a cracked jey crack’n’fail).
However I think the baggage handlers do as much damage as riding the things…
