About this guide
A frame adapter bar creates a temporary level attachment point for a bike with a step-through, suspension, BMX or other nonstandard frame on a compatible hanging-style rack. It does not increase the bike rack’s weight rating. Check both the bar’s published constraints and the rack maker’s approved bicycle fit before transport.
