The Road Bike Adapter slides into Evoc's Travel Bag and protects the front end by encasing the fork with padding. This elevates the front and helps secure the rest of the bike in the bag. The Road Bike Adapter is constructed from 600D nylon that's PU-coated for durability, and measures 17 x 10 x 33cm. Please note, it is not to be used in combination with the Road Bike Aluminum Stand.
