What Our Gearhead(R) Experts Are Saying: "I like these frames when running panniers up front or with heavier loads. They add stability and make it easier to position bags exactly where you want them."Once a rack is in place, fine-tuning how cargo sits can make a big difference in ride quality. The Side Frames Set for Tour Rack adds that extra layer of control, giving panniers a more stable, supported place to sit. Designed to integrate cleanly with the Thule Tour Rack, it opens up more mounting options without complicating the setup.
