Named after the 'Queen of the Classics', Paris-Roubaix, the Challenge Paris-Roubaix Open Tubular Clincher Tyre is made to handle the rigours of rough road riding, including cobbles!
Featuring a high 300 thread count casing and a finely knurled tread pattern for superb traction, the Challenge Paris-Roubaix Open Tubular delivers excellent control and race winning speed.
The Challenge Paris-Roubaix boasts a lightweight Aramid bead for compatibility with ETRTO standard clincher bead rims and a high thread-count, plus a SuperPoly casing, which increases suppleness and reduces rolling resistance compared to regular Poly casings.
Handmade - Every Challenge tubular and open tubular is produced by hand. This handmade process minimizes the use of heat treatments and specifically avoids the industry-standard extreme heat treatment called vulcanization. By resisting these common practices, Challenge is able to provide the ultimate quality standard in high-performance products. Our handmade production allows our treads, casings and inner tubes to maintain their original suppleness and flexibility, achieving the best grip for controlled cornering, rapid accelerations and flat-out speed. A supple Challenge tire is able to absorb and reduce harmful vibrations passing from the road to the body, normally produced by riding stiffer vulcanized tires, ultimately reducing muscle stiffness, inflammation and fatigue.
Puncture Protection System (PPS2) - The Puncture Protection Strip is a special aramid fabric placed between a tire’s tread and casing to increase resistance to punctures. Some tires designed for use on rough roads, cobbles and gravel receive PPS2, an additional layer of PPS between the casing and the inner tube.
Open Tubular - An open tubular is constructed using the same casing and tread materials and process as a tubular, but instead of sewing the casing together (closed), the sides of the tubular casing are folded around aramid fiber cords to produce beads. This ‘open’ design performs like a tubular, yet conveniently mounts like a standard clincher tire. If combined with a Latex inner tube the ride becomes even closer to that of a tubular, offering excellent traction and cornering, low rolling resistance and shock absorption.
