The well-thought-out bag supports and racks are products that make the everyday act of carrying luggage an exciting adventure for adults.
The Rear Cradle attaches to the seat post and functions as a support platform.It is a convenient way to attach a sleeping bag, dry bag, or other small items.
The free-swinging design of the Rear Cradle allows the user to place a bag or other item between the saddle rail and the Rear Cradle to stabilize the load and prevent the seat pack from swaying side to side, thus preventing the load from collapsing.
Furthermore, the design allows rotation at the clamp portion of the seat post, so it can be adjusted in angle and position to fit a variety of vehicle bodies.
*Can be attached to a seat post of 28.6mm or smaller.
Shims for 27.2mm diameter are included.
