I have a Biknd Helium 4 P5X Bike Bag. Only used a couple times. Includes all the padding and accessories.

Details:
The Helium V4 bike case was created for globetrotters who travel with their bicycles on airplanes, trains or buses. Traveling with a bicycle has never been this simple: the Helium V4 is light and easy to carry and its revolutionary inflatable padding offers unrivaled protection. Thanks to its minimal dimensions, it fits easily in the trunk of even the smallest cars. Every small detail has been looked into: the Helium V4 bike case has special compartments for an extra wheelset and also for stowing you helmet, shoes and other essentials (pump, spare tubes, etc.) Developed with the input of pro cyclists, whose lives involve frequent air travel with bikes, The Helium V4 is simply the best bike case on the market today. The Helium case is light, offers unsurpassed protections against impacts and allows you to pack your bike with only minor disassembly and without changing the adjustment of its components.

Asking $500 in Colorado and would prefer not to ship. PM for pics
