This year Thule sponsored the race series I promote. They have a wide range of products and a good dealer base.
On the west coast there is RV-Inno or INNO (not sure how they brand themselves). They're compatible with the Thule/"European" bar.
I own a combination of RV-Inno (bars, some mounts) and Thule (feet, tandem mount). They work well together and are solid. We've carried 3 bikes (one a tandem) for relatively long trips (5 hrs each way).
