Update: Just back from Calpe with the BBA, not that impressed. The hinges didn't line up on one side after I put the bike in the box and needed some "persuasion" to enable me to close the box. The front wheel, with 25c tubeless tyres didn't fare too well either, very difficult to locate and it unseated the tyre so I had to use the wheel with an inner tube while I was away. On the return the benniconnect bus driver rammed the box in the boot wheel side down and as the pick ups continued loaded other suitcases on top, when we got to the airport the box had a distinct hollow in it, I was dreading unlocking it and seeing what damage had been done.
To be fair all was well but it wasn't a great experience
