Challenge PARIS ROUBAIX SC-S 27mm Clincher Tyre : Cotton OPEN TUBULAR

Brand:Challenge

Code:CH-HC-00550

Created back in 2010, the Challenge Paris Roubaix tyre has rapidly become a favourite tyre of the Pros. Ridden extensively in - yep, you guessed it - Paris Roubaix and the early season Classics, the Paris Roubaix SC-S is an ultra compliant, fast rolling tyre with monumental levels of grip and control.

Arguably, nothing holds more importance than your tyres. They determine how fast you go, how you corner how comfortable you are, how long you spend with your wheels out and - handling aside - how likely you are to 'touch-down' to use the parlance of the pros. Key among a tyre's attributes is suppleness and this is what you pay for.

Challenge have been around since 2003, after failing to secure a license from Pirelli to use the Clément trademark (a brand he had long been supplying and servicing), Max Brauns and subsequently his son and daughter have continued to define the tubular and open-tubular tyre market with huge success - globally - at all levels of all cycle sports; from Triathlon to Cyclocross.

Supple tyres not only offer a sublime ride, they reduce rolling resistance, and enable more precise handling and a greater range of pressures. They adapt quickly as the tyre changes shape while cornering and rolling, which increases road surface contact and grip while cornering, plus shock absorption as you pass over irregularities in the road or trail. Suppleness stems from many areas and Challenge's aim for their tyres is to optimise this at every possible juncture while at the same time balancing costs to offer a range of tyres suitable for various levels of rider or for training and racing conditions.

Challenge make a range of hand-made Tubular and Open-Tubular tyres and the bulk of these feature non-vulcanized construction. Ultimately the major difference between a Handmade Tubular / Open Tubular and the majority of clinchers is that it will avoid the heat and pressure process called vulcanization, which most tyres undergo in production. Vulcanisation is used to bind the materials, but compromises the ride quality when the rubber gets stiffer. For Challenge handmade open tubulars, the rubber treads are hand-glued onto the casing allowing the latex and rubber to maintain their ideal qualities. In addition, thread count (TPI) plays a major role in the weight, suppleness and durability of Open Tubulars. The higher the number of threads per inch (TPI), the thinner each individual thread, making a thinner and lighter casing and a more supple tyre, with lower thread counts resulting in casings that are thicker and more durable. The Paris Roubaix SC-S Open Tubular 27 features 300 threads per inch - the same as the Tubular but with a sidewall made from corespun cotton. While this is lower than the equivalent 'cross tyres, it is perfect for the given use of the tyres which are likely to be run at higher pressures and which need to be slightly more durable.

The Corespun Cotton casing used in the Paris Roubaix SC-S is slightly less expensive than the Silk used in the top end of the range Ultra S tubular, but more durable too and it offers improved suppleness and control over the cheaper Superpoly polyester of the Pro. This construction offers the closest feel to a top end tubular for riders looking to get the best out of their tyre but without the potential awkwardness of tubulars. In addition to the TPI and hand-glueing of tread, Challenge use locally sourced (Thai) natural rubber rather than synthetic rubbers for their tyres. Again, natural rubber is more supple and the grip far superior.

Tubular tyres have long used Latex for their inner tubes but Challenge have taken this element even further in their quest to create the most supple ride. Back in 2006 Challenge created their first seamless latex tube to be used in tubulars and also to be available for use in Open-tubulars and clinchers. Produced in their own factory from locally-sourced materials, these tubes have elastic and absorptive qualities that enable a larger point of contact than a butyl tube. The added elasticity reduces rolling resistance and enhances comfort and speed, making latex an ideal material for racers at the top level of the sport. If you want to get the most from your Challenge Open-Tubular or clinchers then we highly recommend latex tubes. In real terms they are good for 2-4 watts out on the road.

Given the intended application - cobbles, hard packed dirt and rough roads and the subsequent increased risk of puncture, it makes sense to offer some security against flats and Challenge achieve this by placing a double layer of PPS (puncture protection strip) between the casing and the tread. This unique fabric adds little weight but a huge amount of peace of mind.

Whether you are a regular endurance rider, a little bigger than most pros, or regularly testing yourself on tough roads then the Challenge 27mm Paris Roubaix SC-S should be on your list of go-to tyres. If you love to beast yourself over the cobbles of the Paris Roubaix, Flanders or the like, then these are a must have
