Bike Pro USA Double Race Case. https://www.bikeprousa.com/dbl_racec...3412.27.55.210

I have a Bike Pro USA race case and Bike Pro USA Tandem Race case. Both are great. Have flown overseas with both with zero damage. The metal frame that the bike frame bolts to gives it great protection.

I haven't used the double case so I can't vouch for it. However, I could see some advantages. $625for a case is a lot, but it's the equivalent of 2 $315 cases.

Also I'm guessing that the airlines would only charge you one $80 bike fee, instead of two, but that's a guess.
