Thule bike rack crossbar frame adaptor

Practically new. Used once. I have 2 of these. Will offer a deal if you buy both. Detail: Durable rubber collars secure easily and safely to bike stem and seat post New push button clamps for quick installation and removal Unique, ovalized tubing prevents unwanted rotation Telescopic adjustment for all size bike frames Keeps bike securely centered and mounted on hanging style rear mounts The Thule Frame Adapter is designed to allow bikes with non-standard frame geometries to fit hanging-style bike racks. The loops at the end are intended to fit loosely around the handlebar and seat and utilizes gravity to keep the bike in place. The Frame Adapter is sized to provide a mounting place for Thule hanging bike racks, so has a fixed size that may not be compatible with every bike. It has not been tested nor guaranteed to fit every possible bike model, so may not be compatible with smaller bikes, or those with truly unique shapes
