Over washboard and roots with a fully loaded rig, the Switch Direct Mount Adaptor keeps the Switch Rack bolted straight to the frame. These aluminum rack adaptors convert the thru-axle rack to direct mounting on frames with horizontal, in-line M5 mounts. All mounting hardware is included. What Our Gearhead(R) Experts Are Saying:"Loaded for a rough gravel weekend, the rack never shifted and I never retightened a bolt. Bolting it to my frame's dropout mounts took one short sitting."
