I travel a hell of a lot with work and luckily get to take my bike most times. I generally take my gravel bike these days as that gives me more options for riding, so I take a Scicon box (bike is currently packed in it for a recce trip to Japan). I just leave my bike built up in my hotel room and have had no issues. Although we do tend to take over entire floors or entire hotels – so maybe that helps…
But I’ve also used an Evoc for many years, so as above can thoroughly recommend one. I used to always take rotors off because I’ve seen too many pringled rotors from robust baggage handling and luggage hold stacking. It only takes a few minutes to take them off and put them back on again (centre-lock even quicker).
I love getting to a completely new place and going for a blast and explore – especially when its winter here and warm and sunny at my destination. And as you say get to meet some great people.
