Thule's Helium Aero 3-Bike Hitch Rack is light and sleek for easy handling, installation, and removal. Thanks to Thule's Hold-Fast cradles and No-Sway Cages with dampening elastomers that abosorb road shock, your bikes ride in complete security. Its aerodynamic aluminum design improves ground clearance for peace of mind on bumpy roads. The Snug-Tite Stinger adjustment knob eliminates rack movement by removing space in the receiver, while the Helium Aero attaches without tools for quick installation and removal. Plus, the arms fold down for storage when not in use, and the whole rack tilts out of the way for easy vehicle access.
