Product information "Challenge Almanzo Pro Gravel Reifen 28x1,3" Zoll"
Challenge Almanzo Pro Gravel Reifen 28x1,3" Zoll
Light profile for gravel roads / gravel races and low rolling resistance on the road. Best traction in curves paired with the flexible Challenge casing make this tire unmistakable.
Pro Handmade Tubeless Ready with Superpoly casing
Handcrafted tires combine a multitude of outstanding properties to offer the highest level of comfort and the lowest possible rolling resistance. Carefully selected materials are used in the various tire levels depending on the usage. Soft, supple carcasses adapt quickly to the shape of the ground when rolling and when cornering. This increases ground contact and grip and improves shock absorption on poor road surfaces. Soft, natural rubber profiles are combined with light, flexible puncture protection.
Polyester is the cheapest of all handcrafted carcasses. It is a synthetic material that is very strong and impermeable to water and offers considerably more flexibility and durability than comparable nylon materials. Challenge uses high quality polyester or SuperPoly (polyester with a higher TPI number) to produce cost-effective pro-level tires.
Puncture Protection System 2 (PPS2)
Some tires that are 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, they offer unrivaled puncture protection thanks to an additional PPS fabric layer between the carcass and the tube.
