this blackburn rack was easy to install despite my original worries. has multiple adjustments to accommodate a nice range of bicycle sizes and tires. feels very secure when fully loaded. the rails are set perfectly far apart to easily remove panniers when you arrive at your destination. i was concerned with the racks weight but for what it provides in stability and carrying capacity it is right there with all of the other similar models. westernbikeworks.com still beats the competition with fast shipping and affordable prices. don't bother shopping elsewhere...this is your go to shop and product.
