The Gravelking SK is by its profile even more aggressive than the Gravelking with its Mixte tread. The aggressive profile, the natural ZSG rubber compound, the puncture protection and the special AX-a- carcass for lower rolling resistance, make the Gravelking SK an all-rounder.ZSG (Zero Slip Grip) Natural CompoundThis compound has the same low rolling resistance as the premium compound. Its increased abrasion resistance makes it perfect for a durable training tire with excellent handling.AX-α (Advanced Extra Alpha Cord)AX technology uses extremely narrow threads woven into the casing at a very high density to provide lightness and flexibility. This increased density improves resistance to cuts and friction.Anti-Flat CasingThe reinforcement throughout the tire increases resistance to punctures and punctures.Tubeless Compatible (TLC)Tires with the "Tubeless compatible" feature, can optionally be driven with the help of a sealing milk without a tube.Product image shows the same product in a different size. - Details: - Tubeless ready up to 60 psi - Wheel size: 28 inch - Included in delivery (quantity): single - Purpose: Gravel - Weight: 540 g - E-bike compatibility: without manufacturer's recommendation Tires - Pressure (Bar): 2.7 - 3.5 - Pressure (psi): 40 - 50 - Tire size in inches (diameter x width): 27.5 x 1.9 - Tire size ETRTO in mm (width x diameter): 48-584 - Type: folding tire - Puncture protection.
