A quick video showing the Bontrager lightweight back rack paired with the Arkel dry lite pannier fitted to my Trek crossrip. I was trying to find some information as to whether or not this set up would work with my smaller size frame and also exactly how they installed. I went ahead and bought the stuff and it worked out! I was pleased with the quality and the fit is good. I made this video to add some clarification and hopefully this will help you make a decision for your own light touring set up.

correction the brake bridge adapter has threads on both sides you would use both arms not one.
About my bike it's a trek crossrip 3 aluminum frame with regular quick release axles. Shimano 105 groupset. This is a great all around bike, capable of wider tires for gravel and rough roads yet light and quick enough for the road. It has mounts for racks and fenders too. It has a pretty high stack and short reach, I really like the fit on it and it's disappointing they stopped making this model because it's truly a do it all bike.
