Reinforced with a rugged polyethylene construction and foam padding, the Thule Round Trip Sport Bike Travel Case protects your favorite bike from overzealous baggage handlers and rough airline transport. Four heavy-duty straps bolster the case's contents from coming undone during transport, while integrated wheels make for easy rolling. The case splits in half for fast loading, with an internal divider separating your frame and components from the wheels for added peace of mind. It's roomy enough to fit most road and cyclocross bikes, also accommodating smaller mountain bikes. Internal dimensions are 45 x 28. 5 x 10in, with the external dimensions coming in at 47 x 30. 5 x 10. 5in.
