John C.wrote a review of Thule Echelon Roof Bike Mount on November 17, 2008
Beautiful, asethetic design. Solid and well built. Easy to install. Excellent product. Yes, you need the X9adapter but many parts in the adaptor package you don't need. Thule should just sell us 2 square base screws. However, I notice there is some whistle blower wind noise, perhaps from the Rapid Area bar and the mount. Any one has an idea?
