Arkel Randonneur Bicycle Rack with the Tailrider Trunk Bag

I purchased both items from Cycle Touring as per descriptions below - items are like new.

Arkel Randonneur Seat Post Rack

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.

Weight: 495g

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 then you need the Brooks Saddle Adaptor

Tail Rider Trunk Bag

A beautifully sleek trunk bag packed with features like waterproof zippers, insulated panels, various pockets and an internal divider. It has a built in rain cover and also expands from 8 to 11 litres to take a surprisingly large load. The Tailrider attaches to the top platform of the rear rack with reflective Velcro straps. Please note that this bag has no padded handle on top.
