The Strada is Challenge’s go-to champion for efficiency and sublime road feel. This high performance tire combines a supple rounded profile that takes the sting out of rough pavement with a construction that provides maximum control and very low rolling resistance.

This handmade PRO Series tire combines a supple Super Polyester casing with our SMARTprime tread compound, our fastest rubber yet. Our new Easy-Fit Shape moulding process gently pre-forms the tire for easier mounting and inflation.

CONSTRUCTION: Handmade
Challenge handmade tires combine comfort, performance, and grip in a way other tires can't match. Our handmade tires are assembled step-by-step by experienced craftspeople. High quality natural glues and latex coatings are applied to ultra-supple casing materials like silk, cotton, or polyester. The result is a small-batch tire with a ride feel that is simply on a different level.

SERIES: PRO
Everyday Luxury – Our workhorse handmade tire is the PRO series, delivering performance and ride feel unmatched by traditional vulcanized tires. Perfect for the rigors of daily riding.

CASING: Super Polyester 300TPI
Super Polyesters with higher thread counts of 220-300tpi make up our most affordable handmade casings. Polyester is much softer and stronger then nylon, is impervious to water and quite durable.

COMPOUND: SMARTprime
Delivers lower rolling resistance than our basic SMART compound without sacrificing traction or durability. SMARTprime rubber compound forms the basis of our fastest road tires yet.

PUNCTURE PROTECTION: PPS Ganzo
PPS Ganzo is the ultimate single-layer puncture-protection fabric. PPS Ganzo offers greater security while maintaining low weight and rolling resistance.
