It's so good to see the evolution of the bike travel case from the past decade. What we've got here is the biknd jetpack with air protection for your ride. See the yellow under the wheel closest to us? It's an inflatable donut that will help to keep outside pressures from aiding in damaging your ride. The aluminum frame base keeps the weight down significantly and adds to protecting your pride and joy too. At $450 USD you'll be able to travel with your XC, DH, FR, or Road bike and have piece of mind with it in the biknd jetpack.
