The Single Mount attaches one rack. This option is the less expensive version of the crossbar option but is the perfect solution if you are only looking to load one bike. You can also install 4 to 5 single mounts on a full-size truck depending on your model. Most smaller trucks can have 3- 4.  The single mount requires drilling into the front of the truck bed or attachment to an existing C channel etc. The rack is easily removed but the mount remains attached to the truck. If you have questions about your truck please email us at info@Ride88.com and we will be happy to work out the best solution.   Please allow 7-10 days for shipping and handling.
