Our vision: Faster Trails, Safer Journeys. We created a premium innertube - street, trail or city - developed for the optimal cycling experience. The Ultraverse pack contains 2 Inner Tubes and 2 Nylon Tire Levers. Our standard tubes use a molded method of construction, ensuring a consistent thickness of butyl rubber. This offers more durability, better air tightness and longer lasting tubes. The nylon plastic tire levers are different from the metal ones preventing excessive force, and not damaging alloy rims. Valve Type: Schrader/ Auto Valve. Doesn’t require a special pump to inflate in comparison to the Presta valve and are structurely designed for modern wider rims. Valve Length: 37mm How to Choose Your Size: To determine the size you need to check the side wall markings on your tire where you’ll see two numbers separated by an 'X'. The first number refers to the tire’s diameter. The second number refers to the tires width. Select the tube that has the exact same diameter as your tire. Your tires width should fall into the range of widths listed on the tube packaging.
