That case doesn’t list a weight. It looks like a create works, which were rather heavy. Weights are very tight. The difference between 50 and 50.5 lbs could be $100+ round trip. Further a 9 inch width will be tough to pack an MTB and wheels. Packing a bike with rear-wheel installed in 9 inch box is close. With both wheels removed the case would bulge. You wouldn’t be getting the extra protection you purchased. At that point an oversized bike box is better. It also lacks wheels. Lugging bike box through the airport is a bitch. Especially when you are have a tight connection and a customs stop. If purchasing that for an MTB, I’d also get a separate wheel case.
