Tannus Portal Hard Tubeless 700C X 28 City Tire

Like all Tannus tires, the Portal is made using a proprietary puncture-resistant resin called Aither 1.1, which allows the Portal design to replicate the weight and resistance of a standard tire and be the only airless bike tire that weighs the same as the standard tire, tube, and rim combination adopted by many road racers.. In addition to minimal weight and drag, Portal repels the elements and provides a guaranteed 5,000-mile puncture-free ride.. Portal even performs well in wet conditions with improved grip and does not stretch in hot weather. - Portal tires come in different durometers, so be sure to consider how the durometer will affect your ride. Advantages: No air, no punctures: - Our airless tires are made from an advanced material we call Aither 1.1 and are completely solid, but ride like regular bike tires.. Our tires are not susceptible to damage from thorns, nails, glass or even chips.. Never use a Tannus tire pump again. Just ride. Lungs: - Thanks to our Aither 1.1 material, our tires are very light. Starting at 370g, Tannus tyres weigh the same as most tyre+tube+rim tape combinations. Use existing rim: - No need to change the rim. If you have an existing clincher style rim, it can be used with Tannus tyres. Specifications: - Diameter: 700 - Width: 28 - Inner rim width: 18-20 mm
