Tricross rider here.
Keep the racks, buy yourself a bungee net or two, they come in about 12-13' square size, 4 or 6 vinyl coated hooks, available from any hardware store or motorcycle outfit- amazingly strong and versatile system. I hauled home bunch of groceries still in supermarket bags - impulse shopping stop - kept in place by these nets. Watermelon was riding in front!
Ride safe and have fun
