I've previously posted about endorsing the Scicon Aerotech Evolution when someone asks for recommendations. It's expensive but Scicon advertises it as "the world's toughest bike case". Mine is less than three years old and have shipped it via FedX about 10-12X all within the U.S. except once by plane to London. This pic shows how the case was returned to me after Arizona Ironman a couple weeks ago. The hole is where a skewer is supposed to be to hold one of the wheels attached to the inside of the case. Apparently something hit the case hard right on the end of the skewer and pushed it all the way through. I contacted Scicon and received a reply that included "damages as a result of abuse such as tears, cuts, and holes......are not covered by the Scicon warranty". They suggested I use a washer to cover the hole. It appears a better design would have been to include some kind of cover over the skewer opening. So if anyone is thinking about spending the extra money and thinking they will be getting a "bulletproof" case, here's an example that may get you to rethink the "investment" and consider alternatives.
