Challenge Criterium SC folding tyre

World-class tyres for the road: rolls fast and excels in corners. The Criterium offers low rolling resistance and optimal grip, whether on wet or dry roads.

Challenge Handmade Clicher tyres have been the first choice of numerous professional road cyclists for many years. Numerous victories in classic races, as well as further podium finishes, have proven that the Criterium is one of the best pro racing tyres. The Corespun cotton-polyester casing ensures outstanding suppleness, stability and lightness. The high thread count of the casing reaches 320 TPI, offering excellent grip, minimised rolling resistance and increased comfort, resulting in significantly better bike handling. Maintenance is also less demanding than with tyres featuring a silk casing. Equipped with a Puncture Protection Strip, an additional layer of high-strength fabric between the casing and the tyre to reduce the risk of punctures.

Servizio Corse SC Handmade Clincher with sealed Corespun cotton carcass

• Handmade tyres combine a variety of outstanding features to offer maximum comfort and minimal rolling resistance. Carefully selected materials are used in the various tyre grades depending on performance requirements for specific applications. Soft, supple casings quickly adapt to the shape of the road surface when rolling and cornering. This increases ground contact and grip and improves shock absorption on rough roads. Soft, natural rubber treads are combined with lightweight, flexible puncture protection.
• Corespun cotton casings are used in the Servizio Corse Series Track, TT, Tri and Road tyres, as well as the Team Edition Series Cross tyres. Cotton is – just like your favourite shirt – naturally softer and more supple than a cheap polyester shirt and requires more careful handling. If not washed and dried properly, cotton is more prone to absorbing water, stains, mould and rot than more durable polyester or more expensive silk. That is why cotton benefits greatly from the Challenge casing sealant. It makes cotton the ideal casing material for professional athletes, as it offers an ideal balance of price and performance.

Handcrafted natural rubber – Smart hardness

• Challenge’s handcrafted natural rubber treads are formulated to offer the perfect level of durability without compromising on performance, comfort and control. Although Challenge tyres wear out 10–20 per cent faster than the competition’s, they score highly with significantly improved performance and a noticeably better riding experience throughout their entire lifespan. Depending on requirements, the tyres are fitted with rubber compounds of varying softness.

• The Smart hardness grade is the version of Challenge’s natural rubber compounds optimised for long life.

Puncture Protection System (PPS)

• The PPS Puncture Protection System consists of one or more layers of fabric between the tread and the tyre carcass. PPS significantly increases the tyre’s resistance to punctures, thereby offering maximum reliability.
