From minimum maintenance to decaying pavement, rolling hills to near vertical climbs, Rampart was made for those who wish to conquer any road. These tires were designed and inspired by experiences riding and racing courses of varied terrain, and the uncharted routes that connect them. The Rampart offers increased volume and an ultra-smooth ride quality on rough pavement (and well beyond). The 28mm, 32mm, and 38mm widths fit modern disc geometry frames to add even more comfort and traction. - Durable casing: Features a layer of woven aramid fiber reinforcement between the outer rubber and the inner casing under the tread. This material is twice as strong as Kevlar and lighter in weight than any competitive product. It provides moderate protection against abrasion and sharp road debris that may result in a flat tire. - Light & Supple casing: When extra puncture protection isn't necessary, light and supple casing offers decreased weight and a comfortable, ultra-supple ride quality at lower pressures when set up tubeless.
