Arkel Randonneur Rack
Seat post rack with dual attachment points to provide unequaled strength and stability.
This seat post rack is strong, light, stable, goes on and off in seconds. A sleek quick release bracket attaches to both sides of the seat rails, forming rock-solid attachment points. The front of the rack gently envelopes the seat post with a soft rubberized clamp that is secured with a velcro strap. The three point attachment system of the Randonneur Seat Post Rack® brings unequalled stability - it feels like it's bolted on to the frame! Move it from bike to bike depending on what type of riding you want to do.
Fits most bikes including road bikes with carbon seat posts.
between the seat rails and the top of the bicycle seat tube is 4 inches (10cm).
