The Arkel Randonneur Seat Post Rack is a sleek cantilever type rear rack. It attaches to the seat rails and rests against the seat post with a rubberised clamp. The stress on the seat post is thus minimal compared to regular beam racks and the seat rail attachment gives superior lateral rigidity. The Randonneur Rack is installed or removed in seconds and fits most bikes including road bikes with carbon seat posts.
Max load: 6kg
Minimum clearance required between seat rails and top of seat tube: 10cm for short setup; 18cm for long setup.
If you have a Brooks saddle the you need the Brooks Saddle Adaptor
