Thule has been known for making outstanding racks for bicycles of high quality; the Thule BIG MOUTH™ is no exception. The 599XTR is designed to fit on many after market and factory cross bars 1¼" or smaller - round or square. Once the bicycle rack is installed onto your roof, hoist your bike onto the track and secure the frame into the open jaw clamp. By snapping the handle closed, the jaw snaps shut securing your angled frame in a rubber cushioned clamp. Secure each wheel to the BIG MOUTH by ratcheting the straps around the rim and locking it down. The high quality BIG MOUTH 599XTR from Thule is a premium bicycle roof rack that saves spaces and won't break the bank! View our available cargo accessories below.
