Lighter, slimmer, & ultra-strong, RockyMounts’ redesigned SplitRail LS is a hitch-mounted rack built to carry 2 bikes but can expand to 4. It fits 20”- 29” wheels & tires up to 3-inches fat. People love Rocky racks because they don’t wobble. The design of the hitch mount uses a metal ball to keep things table & that means your bike always stays safe & secure. (photo credit GearJunkie)
