A tribute to the spring classic in Tuscany

Exactly the right choice to leave gravel roads and bad roads behind quickly and safely. Even more puncture-proof and supple thanks to the tubeless carcass. The proven tire in herringbone design proves its performance on rough terrain with a new, gravel-specific construction and an additional beefy 45mm wide version. The STRADA BIANCA is the perfect tire not just to roll over rough asphalt, cobblestones, sandy or hard ground, but to float.

Pro Handmade Tubeless Ready with Superpoly casing

Handmade tires combine a variety of outstanding properties to offer the highest level of comfort and the lowest rolling resistance. Carefully selected materials are used in the different tire levels depending on the use and performance requirements. 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 roads. Soft, natural rubber treads are combined with lightweight, flexible puncture protection.

Polyester is the cheapest of all handmade carcasses. It is a synthetic fabric that is very strong and waterproof, offering significantly more flexibility and durability than comparable nylon materials. Challenge uses high quality polyester or SuperPoly (higher TPI number polyester) to produce cost-effective pro-level tires.

Handmade natural rubber - Smart durometer

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 offer significantly improved performance and a noticeably better ride throughout their lifetime. Depending on the requirements, the tires are equipped with rubber compounds of different softness.

Puncture Protection System 2 (PPS2)

Some tires designed for use on rough roads, cobblestones and gravel are equipped with the PPS2 (Puncture Protection System 2). In addition to the normal PPS protective layer between the tread and the carcass, these offer an unrivaled high level of puncture protection thanks to an additional PPS fabric layer between the carcass and the tube.
