While we often stand on our soapbox to advocate tubeless technology for mountain bike tires, the truth remains that we always carry tubes with us on serious adventures into the backwoods. At that point we want something economical and reliable. These Michelin MTB Airstop Presta Tubes are all of that thanks to their traditional butyl rubber construction. Of course, tubeless or tubes is a personal choice and if you use tubes on a regular basis, Michelin Airstop Tubes are perfect for that as well. They’re light enough and offer excellent puncture protection. They’ll work in any 26″ mountain bike tire from 1.5 – 2.2″ widths.
