SUPER LIGHT, SUPER FAST, SUPER GRIP! After a decade of making true Tubeless tires (without the need for liquid sealant), we wanted to squeeze out as much weight as possible. To achieve this weight reduction we adopted a Tubeless Ready system for our Formula Pro Super Light (S-Light). Formula Pro S-Light Tubeless Ready is made with our new high-grip compound, RBCC˛, to combine incredible grip with improved tread life. TECHNOLOGY TUBELESS READY: Can be used with or without inner tube 180 TPI SHELL: Tough and supple with sublime road feel SUPER LIGHTWEIGHT: New lighter construction for faster and more flexible handling NEW RBCC 2: Innovative new RBCC 2 provides great grip in all road conditions DISC BRAKE APPROVED: Specially designed casing and bead protection make the tire compatible with disc brakes BEAD PROTECTION: provides extra protection against bead snagging, as well as a watertight seal when properly mounted
