Anyone who's traveled with their bike has horror stories of scratched frames, lost parts, inattentive baggage handlers, and the general unwieldiness of traveling with a bike. The Evoc Bike Travel Bag Pro solves for most of these common issues, starting with its construction. Evoc found that the levels of protection offered by a hard case versus a soft case was profoundly different until the cases were loaded with heavy items not typically encountered in airline travel, so it opted for a soft case for maneuverability and malleability. The primary difference between the regular and the Pro bags is the removable wheels, sturdy aluminum handle, and the inclusion of Evoc's Road Bike Adapter, common sense features requested by those who travel with their bikes in all kinds of places, where sometimes a handle is far more important than wheels (think buses in remote areas). The included Road Bike Adapter is especially useful in those situations, as it adds an additional layer of protection to the fork while better securing the bike. Like the bag's outer fabric, the adapter's face material has been treated with a PU coating to resist water, so it fends off the elements as well as impacts should your bike end up jostling atop one of those buses while it's raining. To pack the Evoc case, you remove the wheels and loosen and turn the handlebars. Padded straps hold the frame and fork in place, and separate wheel pockets hold the wheels. The Road Bike Adapter straps on like a feedbag, if you decide to use it. The Bike Travel Bag also features a variety of handles in intelligent locations to make hefting and moving the bag easier, and there are also inline skate wheels for when you're running through the airport to make your flight. The Evoc Bike Travel Case will hold 29ers, TT bikes, road bikes, and cyclocross bikes without batting a proverbial eye, but note that the Road Bike Adapter isn't compatible with Evoc's Road Bike Aluminum Stand.
