I own two cases: One hard, one soft. The hard case is a Trico Iron case... I've had it for over 10 years. But this thing requires a lot of disassembly and its tight to disassemble/reassemble. I've also suffered damage when it was opened/inspected somewhere between Newark airport and Geneva. Very hard to get it packed correctly.
So, I don't reccomend that case, unless you are shipping a bike.
The second case is a BikeProUSA Race Case. The first time I saw one was back at the 99 USPRO on Philly when I met Salivatore Commesso, and the other Saeco riders at our hotel. I figured if the Euros use it to travel abroad without a spare bike... its gotta be decent. They had 5 or 6 of them in tow.
Anyway... whats great about it is:
• Stands up on wheels on its own
• It had super-thick 2-3" foam on all sides
• Ballistic nylon construction
• The frame clamps to a internal frame
• The case will hold one bike, plus two sets of wheels.
• They can be custom made for oversize bikes.
I've taken the thing to Europe 5 times since without a hitch. Plus, you can remove the internal frame with 4 bolts, and roll the thing up (I carry a bag of those blue Thule cinch straps - never now what you're gonna need to strap down to a rental car...) and strap it into a 4' x 1' roll. Two of them fit into a small trunk.
Anyway... take a look at this website:
