American Classic Krumbein Tubeless Folding Gravel Tyre 650b x 47 - Tan
KRUMBEIN
The Krumbein is American Classic's most aggressive gravel tire ideal for gravel roads, loose trails, and fast singletrack. The all-weather design includes tall side lugs for cornering grip on loose and rocky conditions, chamfered center knobs minimize rolling resistance, and there is plenty of space between knobs to prevent mud build-up. Combined with our signature Rubberforce G tread compounds and Stage 5S Armor construction, this tire provides impressive grip in the dirt and improves both ride quality and abrasion resistance compared to its predecessor.
