Beargrease is a fat-tire bike built to deliver the control and composure of a modern trail mountain bike. Its long, stable wheelbase and balanced weight distribution make it easy to find traction and navigate loose, steep terrain, while the 27.5 x 4.5" tires provide exceptional float and grip. Rack, Three-Pack, and accessory mounts offer ample space for race-day or all-day gear. Whether you are tackling winter ultra events, riding snowy singletrack, or exploring rugged terrain, Beargrease is ready for the adventure.
- UDH-ready carbon fiber frame is stiff for efficient pedaling, keeps weight to a minimum, and helps reduce trail vibration for a smooth ride.

- 27.5 x 4.5" fat tires deliver excellent traction and float while rolling smoothly over rocks, roots, and other trail obstacles.
- Redesigned Bearpaw Carbon fork includes two sets of Three-Pack mounts, mini-pannier compatibility, and support for suspension forks up to 100mm travel.
