EXPAND YOUR BIKE RACK'S CAPACITY WITH SUPER DUTY ADD-ONS.

Constructed from durable, corrosion-resistant aluminum, the Super Duty Add-On is designed to handle bikes with ease, whether you're on or off the road.

Its tray-style system secures your bike by the tires, preventing scratches or wear on your frame and fork. For bikes over 75 lbs or rougher terrain, the optional Wheel Chock adds extra stability by reducing steer tube rotation.

The new one-handed operation makes loading and unloading a breeze. Just press the red button and rotate the arms upward— the ratchet system disengages, allowing the arms to lift easily with one hand. Press the button again to close the arms, and a series of clicks ensures they're securely locked. The versatile design accommodates bikes from 16" kids' models to 29ers and even fits 5" fat tires without needing a spacer kit.

Add one or two trays to your SD base rack to carry more bikes on your next adventure.
