Lightweight suitcase for folding bike
As the airlines squeeze us more and more, it's getting increasingly hard to carry a bike, folded up or otherwise, on account of the weight. Every kg they shave off the checked bag allowance is a kg that has to come off the bike and gear, as the suitcase still weighs the same. Recently, allowances dropped from 23kg (~50lbs) to 20kg (what a nice, round number!). So maybe it's time to find a suitcase that weighs a kg or two less.
I'm looking for some good suggestions. Right now, I own a Samsonite hardshell. It protects the bike well and takes a beating. However, I'm just certain that there must be some kind of better way to do it. Anyone know of any good, light suitcases out there, or perhaps other intelligent ways of moving bikes around without them falling victim to an airport's baggage throwers?
