Carbon performance, fat-tire confidence: that’s what Beargrease brings to every ride, from groomed-trail races in the dead of winter to summer trail bike duties. Beargrease is a highly nimble carbon fat-tire bike, thanks to its efficient frame, trail geometry, and 27.5″ wheels. Bottle and cargo mounts on the frame and fork make it easier to fuel endurance rides or bikepacking journeys. Factor in the rock-solid Shimano Cues 11-speed drivetrain, and there’s nothing in your way.

High-Modulus Carbon Fibre Frame
This material offers improved stiffness, better vibration damping, excellent durability, and weight savings compared to other frame material.

Beargrease Geometry
long front/center, short stem, and wide bars, and 440 mm chainstays create room to move and add confidence while maneuvering on tight trails. This geometry results in a fat bike that rides like a trail bike. It is stable, steers well in loose conditions, and remains nimble and agile despite the massive wheels and tires. The low bottom bracket height is also key to keeping the rider’s center of gravity low, which makes dabbing, dismounting, and remounting easier.

27.5 x 4.0" Wheel & Tire Size
Beargrease rolls on 27.5 x 4.0" wheels and tires. For groomed snow or dirt, this diameter provides increased rollover, a longer contact patch, and the flotation of a 3.8" tire without the added rolling resistance when compared to a 26" wheel.

Bearpaw Fork
The fork included with this frame works with the following wheel and tire combinations: 26 x 3.8–5" on up to a 100 mm rim/27.5 x 3.0–4.0" on an 80 mm rim / 29 x 2.3–3.0"" on a 50mm rim.

Optimal Drivetrain Design with Narrow Q-Factor Cranks
The Beargrease Carbon frame is designed for the best of all drivetrain performance while maintaining narrow fat bike crank arms for less knee stress: 197mm symmetrical rear end for modern rim and tire fit. 100 mm threaded bottom bracket. Rider-friendly narrow Q-factor cranks. 1x optimized frame design. Up to a 32t max chainring.
