I just got back from a trip to Florida. (Returning to 30 inches of snow in Massachusetts. LOL)
I had a hard time packing two 26 inch wheeled mountain bikes in standard bike boxes and bags.
My new bike will be a 29'er, and I'm sure that it won't fit in the Bike Bag that I own. Has anyone taken their 29'er for a plane ride? And if so, which bike box/container works best?
