René Herse's largest 650b tire, the Umtanum Ridge is ready for a challenge. Rolling over boulders and climbing up roots is a cinch thanks to its massive traction patch. And with its heavy-duty casing, the Umtanum allows you to hit the trail at speed with little fear of cuts or punctures. A perfect choice for bikes like the Open WI.DE or Mosaic GT-X.
