Ultra Series
The best of the best - Due to the extreme cost of the silk construction (seta in Italian), ULTRA series tires are mainly used for world championships and Olympic competitions.
Carcass 1000 TPI
Silk is a strong, soft natural fiber with a thread density of over 1000 TPI. The ability of the compliant sealed-silk tires to conform to even the smallest surface features gives you excellent traction and very low rolling resistance.
Handmade Tires
Challenge tires combine comfort, performance and grip in a way that other tires cannot. The handmade tires are assembled step by step by experienced craftsmen. High-quality natural adhesives and latex coatings are applied to ultra-soft carcass materials such as silk, cotton or polyester. The result is a tire from small series production with a ride feel that is simply unique.
Puncture Protection System
Is a light and flexible extra layer that is incorporated under the tread to reduce the risk of punctures caused by thorns or stones.
