Drop bars are not very convenient for most bikes in an airline acceptable 62 inch case unless you do significant disassembly. If you can find bars that work well for you that are more compact than drop bars, I suggest that.

My Airnimal Joey uses 24 inch wheels, so that already does not fit very well in a case of that size, and to get the frame in the case with my wheels I also have to remove the crank arms. With drop bars it fits in the S&S Backpack case, but it is a tight fit.



I also have drop bars on my S&S coupled touring bike, the bike has 26 inch wheels, I use 57mm tires on that bike. The same case is used in both photos.



I have a strong preference for drop bars in headwinds, so I put up with the hassle, but if that is not important to you, I suggest you consider other options.
