"What Our Gearhead® Experts Are Saying: ""I wanted a set-and-forget clincher for big base blocks and fondos—Challenger tube-type delivered. It rolls smoother than I expected, shrugs off debris, and the casing still feels comfortable after long hours. Zero drama, just reliable miles.""When our training calendar stretches from cold base miles to long summer fondos, the Challenger tube-type keeps us rolling. Built around an Endurance Bi-Compound tread for low rolling resistance and confident grip, it layers in a Reinforced puncture barrier so we can focus on cadence, not cuts. The folding-bead construction and durable 66 TPI casing balance road feel with longevity, making this a do-it-all tire for daily rides and ultra-endurance goals alike."
