Constructed from 100% butyl rubber, the Aircomp Ultralight Inner Tube 18-25mm with Presta valve from Michelin delivers a great way to reduce rotational mass without increasing the risk of punctures. Suitable for use with road tyres between 18mm and 23mm wide, they feature Presta valves with removable valve cores to facilitate the use of puncture sealant if so desired and weigh less than 80 grams per tube. The lightweight also translates to more compact pack size, and so these inner tubes will take up less pocket space than standard tubes.
