A tire that excels in every department, weight, rolling efficiency, durability, traction and ease of use. Just as likely to be seen conquering long alpine climbs as it is taming the inevitable decent that follows. A round profile, closely-spaced tread, and supple casing contribute to Peak’s low rolling resistance, while ample traction and braking performance are delivered thanks to siping on every knob and its multi-dimensional Dynamic:A/T compound. Optimized for XC competition.
