I am selling a Performance "Team" branded bicycle travel/shipping box. It was around $300 new and has been used a few times.  The box is rugged yet fairly light. It will hold any standard road bike plus wheels, helmet, shoes, clothing and water bottles easily. Though it has several hold-down straps and foam padding, you may want to include bubble wrap if you have many loose items to ship.

It rests upright on 4 wheels and has a flip-up handle for easy pulling through the airport or elsewhere.

Internal Case Dimensions: 44.5 x 28.3 x 11"; External Case Dimensions: 45 x 34 x 11.5"
Weight: 26lbs

I fly Southwest almost exclusively and they charge a $75 fee for checking this in. I am not sure what other airlines charge.

Asking $100 OBO.
