Botto. I now have one, but when I took my bike in the past I used a traditional bike box. But, it was so well packed. I used a sleeping bag and styrofoam to stregthen the box. It was pure neglect.
Besides another worry. In case they loose your bike. They have an upper limit on what they pay out. No where near the value of the average bike.
I'd still take my own bike.Just not your best bike. and. I knew a friend who went with a group to do the Hawaii Ironman race. Several racers on the plane took their own bikes. One racers bike was ruined even within a hard case. Hard to believe, but he swears it's true. Saw with his own eyes. SO much weight put upon the case, it collapsed. He thought.
