Description Control the beast.
45Nrth's Dunderbeist Fat Bike Tire makes for an excellent rear-tire choice for well-groomed single track. Its aggressive knobs let it hook up in loose or snowy conditions, and a softer rubber compound at the edges help it bite when leaned into corners.
26 x 4.6". Tubeless-ready 120 TPI casing.

Yeah, I got the Flowbeist handling things up front and the Dunderbeist on the back. Good combo, really reasonable price.
