Challenge Strada tubular tire black/brown

The Strada is an extremely comfortable road bike tire that scores on both poor roads and extended tours.

Range of use:

World-class tire for the road: rolls fast and shines in wet corners with tons of grip.

Features:

Pro Handmade Tubular with Superpoly carcass.

Handmade tires combine a variety of outstanding features to provide the highest comfort and lowest rolling resistance. Carefully selected materials are used depending on use performance requirements in the various tire levels. Soft, supple carcasses quickly adapt to the shape of the ground when rolling and cornering. This increases ground contact and grip and improves shock absorption on poor road surfaces. Soft, natural rubber treads are combined with lightweight, flexible puncture protection.
Polyester is the least expensive of all handmade carcasses. It is a synthetic fabric that is very strong and impervious to water, offering much more flexibility and durability than comparable nylon materials. Challenge uses high quality polyester or SuperPoly (higher TPI polyester) to produce cost effective pro-level tires.

Latex Tubing

Latex tubes are strong, lightweight and extremely flexible. They absorb shock and significantly reduce rolling resistance by being able to ideally adapt to obstacles.

Handmade natural rubber - hardness grade Smart

Challenge's handcrafted natural rubber treads are compounded to provide the perfect level of durability without sacrificing performance, comfort and control. Challenge tires wear out 10-20% faster than the competition, but score with significantly improved performance and noticeably better feel throughout their life. Depending on the requirements, the tires are equipped with different soft rubber compounds.
The Smart hardness grade is the variant of Challenge's natural rubber compounds optimized for long service life.

Puncture Protection System (PPS) (25-622)

The PPS (Puncture Protection System) puncture protection system consists of one or more layers of fabric between the tread and the tire carcass. PPS significantly increases the tire's resistance to punctures, thereby providing maximum reliability.

Ganzo Puncture Protection System PPS GANZO (27-622, 30-622)

The Ganzo Puncture Protection System is a highly flexible, even more tightly woven multi-component puncture protection system incorporated between the tread and carcass. The Ganzo PPS makes the tire lighter, even more puncture resistant and retains the smooth, comfortable character of Challenge tires.
