When you combine race-bike technology with fat-tire-bike capability, you get Beargrease. We designed this machine for the world’s toughest winter races, but it still knows how to have fun on snowy and winding singletrack. The carbon fiber frame and fork minimize weight and maximize power transfer. The extra diameter of 27.5” wheels offers more momentum and rollover capability than 26” wheels. Frame and fork mounts for extra bottles and cargo make it easier to gear up for your long days out or even overnighters. Add Shimano’s Deore 11-speed components, and it all adds up to one of the best carbon fat tire bikes out there, whether you’re a racer or just enjoy the feel of a fast and light fat tire ride.

  • Full carbon frame with super stable geometry, combined with a 100mm suspension corrected carbon fork for precise handling
  • Bearpaw fork
  • 12 x 197mm rear spacing, compatible with 170/177 Salsa Alternator rear rack
  • Top tube mounts for Salsa EXP Series Toptube Bag or K-edge computer mount
  • Internally sleeved cable routing, dropper post compatible and 1x-specific frame design
  • Compatible with multiple wheel sizes

    When you buy a bike from Aventuron, not only will your bike ship for free, but you will receive a bike that is ready to ride out of the box.

    We assemble and tune your bike, then repackage it to ship. When you receive your new bike it will be very easy to assemble. You will have to attach the front wheel, handlebar, seatpost and pedals. Most bikes do not include pedals, but we have an extensive pedal selection. We are a family-owned and operated business and look forward to having you as a customer.
