text: The Schwalbe Thunder Bart ADDIX Speed Tire combines Schwalbe's Racing Ralph's grip with the Furious Fred's supremely low rolling resistance. The result is a durable, tubeless ready tire that takes tightly-packed center knobs with taller, burlier side knobs that rolls fast while digging in deep. Featuring Schwalbe's 127tpi Evolution casing the Thunder Bart maintains a supple feel, while their Addix Speed compound catapults this tire into the performance dimension.
