Yakima's StageTwo +2 Add-On offers the ability to upgrade the StageTwo 2" Platform bike rack by adding two additional bikes to provide double the adventure and double the fun! Adding on the StageTwo +2 increases the capacity to four bikes, making the StageTwo bike rack system a great option for those bike enthusaists. The StageTwo +2 Add-On secures the bikes the same way as the StageTwo bike rack using a ratcheting StrongArm hook. The stadium architecture increases ground clearance to clear steep driveways, and the offset tray design decreases bike to bike interference, which in turn improves the functionality of the rack. The forward-facing remote tilt lever makes for quick and easy access to the trunk area. The StageTwo Add-on includes integrated locking cables.  The integrated locking loop allows you to add your own bike lock for extra security on your expensive equipment!
