Beargrease is a fat-tire bike built to roll with the control and composure of a modern trail MTB. A 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 control. Rack, Three-Pack, and accessory mounts offer ample space for race-day or all-day gear. Whether you’re tackling winter ultra events, riding snowy singletrack, or exploring beyond the pavement, Beargrease is ready for the adventure.
- UDH-ready 6061-T6 aluminum frame delivers a high stiffness-to-weight ratio, minimal flex while pedaling, and durable performance.
- Modern trail bike geometry provides stability and control in steep terrain and soft conditions.
- 27.5 x 4.5" tires offer enormous traction and float for maintaining your line on steep, soft, and loose terrain, while rolling smoothly over rocks, roots, and other obstacles.
- Redesigned Bearpaw aluminum fork includes two sets of Three-Pack mounts and mini-pannier compatibility for versatile cargo capacity. The frame also supports suspension forks up to 100mm of travel.
- Internally routed dropper post routing improves control on challenging terrain and makes mounting and dismounting easier in deep snow.
- The main triangle accommodates three bottles on most frame sizes and two bottles on the smallest frame size. Rear rack compatibility requires a Salsa Rack-Lock Seatpost Clamp, sold separately. Direct-mount frame bag mounts are included in the main triangle.
