Strada Pro Tubeless Tire

What Our Gearhead® Experts Are Saying:

"I have been riding the Strada Pro Tubeless Tire on everything from criterium warmups to long training blocks, and the SMARTprime compound is a genuine step forward in rolling speed without giving anything up in traction or durability. The 300 TPI Super Polyester casing has that immediate, communicative feel you get from the best handmade tires, and the Easy-Fit moulding made the tubeless setup faster than any Challenge tire I have mounted before. For a dedicated road build where every watt matters, this is the tire I would spec."

Road racing and high-performance training demand a tire that rolls fast, communicates clearly, and holds up through the kind of repeated hard use that separates genuine performance tires from ones that merely look the part. The Challenge Strada Pro Tubeless Tire was built to meet all three of those demands simultaneously, combining Challenge's most advanced road rubber with a handmade casing construction that machine-built tires at any price point cannot replicate. The result is a tire that feels immediately different under load, one that rewards smooth pedaling with a supple, low-friction ride and rewards hard cornering with the grip and confidence to hold the line.

At the center of that performance is the SMARTprime compound, Challenge's fastest road rubber formulation to date. Delivering lower rolling resistance than the standard SMART compound without sacrificing traction or durability, SMARTprime achieves its speed advantage precisely because it never goes through the heat and pressure of the vulcanization process. The 300 TPI Super Polyester casing supports that compound with a thread count that produces exceptional compliance, absorbing road texture and vibration rather than transmitting it to the rider. Natural glues and latex coatings are applied by hand through Challenge's step-by-step assembly process, producing a small-batch tire with the kind of ride quality that defines the handmade category. PPS Ganzo puncture protection sits between tread and casing as a single-layer, high-security fabric that adds meaningful flat resistance while keeping the overall weight and rolling resistance profile as lean as possible.
