cardboard MTB box
If you mean the newer breed of massive boxes that mountain bikes come in virtually fully assembled, then aye. Gravel bike and two wheel sets easy.
If you use a normal bike box then fuck about taping wheel box’s to it, depending on its final shape, it might end up being too chunky and exceed the max dimensions if you’re posting it.
I got a bike box from my lbs recently and it was fucking massive, it might have been an ebike that came in it. A 54cm track bike could fit in it without taking the wheels off.
Any idea if a cardboard MTB box fit a gravel bike and 2 sets of wheels?
Or, could I use a normal bike box for the frame and stick 2 wheel boxes together to make 1 piece of luggage containing the second wheelset?
