Tires/Tubes

The Strada is Challenge's go-to tire for long days on the road. This all-condition tire combines a round profile that takes the sting out of rough pavement with a construction that provides maximum control and low rolling resistance. This handmade clincher combines a supple, 300TPI SuperPoly casing with natural rubber tread for long distance comfort, confident cornering, and quick handing. This tire includes PPS, a Puncture Protection System placed between the tread and casing to increase resistance to punctures. Handmade - Handmade tires combine many attributes to create the most comfortable and lowest rolling resistance tires. Latex - Latex tubes are stronger, lighter, super supple, absorb shock, and conform precisely to terrain, reducing rolling resistance. PPS - The Puncture Protection Strip is a special fabric placed between a tire's tread and casing to increase resistance to punctures.

MICHELIN's Wild Grip'R2 has a sticky rubber compound and an optimized knob pattern which ensures great handling. The center knobs are fast-rolling in the dry, yet spaced wide enough to promote mud shedding. And, consistently sized shoulder knobs provide predictable cornering grip so you can lean the bike over with confidence.

The Pasela ProTire is available in a wide range of sizes. It incorporates ProTite technology for puncture protection and has two excellent all around tread patterns. A series renewal offering the same basic performance with enhanced puncture resistances. - Urban/Commuter tire - Aramid (Kevlar) folding bead - 40-90 PSI

The Product that Started a Tubeless Revolution Inside this simple bottle is a product that changed cycling. Today's tubeless systems rely on the lighter, more reliable, self-sealing performance of Stan's Tire Sealant. Just two ounces of Stan's in a converted standard tire or tubeless tire can repair punctures up to 1/4-inch almost instantly to keep you rolling. Longer-lasting Stan's Tire Sealant is formulated to stay liquid in tires with even thin casings for up to seven months. Arid conditions require more frequent monitoring of sealant levels, but anti-freezing agents in our special formula allow Stan's Tire Sealant to be used in temperatures as cold as -30° F. One quart will convert up to 16 tires. - First choice of riders around the world for tubeless conversion and flat prevention - Seals punctures up to 1/4-inch (6.5mm) quickly - Stays liquid 2-7 months for long-lasting protection - Premium low-viscosity formula resists freezing to work in environments as cold as -30° F (-34° C) - Natural materials, safe for the environment - Can be injected through valve stems with removable cores compatible with tubes and tubular tires

We all love to stop and smell the roses, but like they say, every rose has its thorn. And as we all know, there's no better way to ruin a beautiful ride than with a thorn in the tube. No need to worry, though, because we designed our Thorn-Resistant Schrader Valve Tubes to combat pesky pricks of all shapes and sizes. Starting at the basis of the construction, we designed the tube to be thicker at the outer side (the part against the tire) in order to stop pesky bits from puncturing all the way through the tube. Then, at the inner side (the part against the rim), it's actually thinner in order to reduce weight. This way, you don't have to sacrifice performance in the name of protection. - Thicker construction on the outer side (against the tire) enhances puncture protection. - Thinner construction on the inner side (against the rim) maximizes weight savings.
