American Classic Krumbein Tubeless 650B X 47 Gravel Tire

Krumbein Tubeless 650B x 47 Gravel Tires. The size: 650B / 47. KRUMBEIN. The Krumbein is American Classic's most aggressive gravel tire, ideal for gravel roads, loose trails and high-speed singletrack. The all-weather design features tall side lugs for cornering traction on loose and rocky surfaces, tapered center lugs minimize rolling resistance, and ample space between the lugs to prevent mud accumulation. Combined with our signature Rubberforce G tread compounds and Stage 5S Armor construction, this tire delivers impressive mud traction and improves both ride quality and abrasion resistance over the previous model.
