Through Authenticate 
The Kwick Tendril is a blend of durability, efficiency, and control. The center of tire has a continuous ridge designed to allow the tire to roll effortlessly, while the corners of the tire have just enough tread to grip on city streets, bike paths, or dirt roads. We have also used a lightly harder rubber compound with our Iron Cap flat protection to prevent you from needing to stop along your ride and increasing the life of the tires.
