    Snow beast.

    Attack snowy fields and mountains filled with beautifully groomed corduroy on the 45NRTH Dunderbeist Tubeless Fat Bike Tire. Billed as a rear-specific tire, the Dunderbeist boasts beefy knobs with wide spacing to dig in on the climbs and hook up in the corners for confident control. Dual compound rubber provides a dose of extra gripping power and durability to last many a winter mile, and its tubeless-ready bead lets you choose between tube-free and traditional clincher setups. The Dunderbeist is designed to pair with the front-specific Flowbeist tire and rims ranging from 65 to 102mm wide.

    Great tread, pitiful side wall

    • Familiarity: I've used it several times

    I'm very disappointed with my Dunderbiest. I've had it on my bike for 3 to 4 weeks, and already the casing closest to the rim has become ragged & porous. It now won't hold the air in a Tubeless configuration, as is advertised by 45nrth. Does 45nrth stand behind their products in any way? This is my first time using their tire - possibly my last.
