Want to bring along some friends or just more bikes? Thule's T2 2-Bike Add-On attaches to your T2 system for additional capacity. This rack carries a wide array of bikes, including ones with 20- to 29-inch wheels, and bikes with up to 3-inch-wide tires. Plus, the smart design secures your rides without touching the frame or removing wheels! And, it can be locked with Thule's One-Key System.
