X-Miles CompoundLower wear because the rubber compound is abrasion-resistant and has been applied thicker on the center tread. There is also an efficiency gain of 8.6 watts per pair of tires compared with the predecessor. This means a gain of 34 seconds at 40 km and an average speed of 45 km/h.HD Protection Bead2BeadThe technology HD Protection consists of textile fibers that, woven crosswise, form a high-density (HD) protection layer. This allows a very good compromise between a significant puncture resistance and a low rolling resistance, without compromising the weight of Michelin competition tires.Since its invention by Michelin and its introduction into the competition field in 1986, the Michelin research and development team has worked year after year to continuously improve the performance of the protective layer. The version HD Protection Bead2Bead is optimized for use in racing. - E-bike compatibility: without manufacturer's recommendation - Purpose: Gravel - Weight: 360 g - Wheel size: 28 inch - Delivery (quantity): single - Features: Puncture Protection Tire - Puncture Protection - Rubber compound: X-Miles Compound - Pressure (Bar): 3 Bar - 5 Bar - Design: Bead2Bead, HD Protection, Skinwall - Tire size in inches (diameter x width): 28" x 1.30" - Density carcass fabric: 120 TPI - Tire size ETRTO in mm (width x diameter): 33C x 700 - Construction: folding tire.
