Built for chasing both winter-ultra finish lines and backcountry campsites, Beargrease combines the efficiency of a carbon fiber frameset with the capability of multiple cargo mounts and 27.5 x 4.0" tires. Shimano's trusted SLX 1 x 12 drivetrain ties the package together with efficiency and reliability. Beargrease is designed to push the limits of the fat bike—snow, sand, and singletrack are now more accessible and more fun than ever.
High-Modulus Carbon Fiber Frame
This material offers improved stiffness, better vibration damping, excellent durability, and weight savings compared to other frame materials.
440mm chainstays, longer front/center, short stems, and wide bars create room to move and add confidence while maneuvering on tight trails. Standover height is improved, allowing the addition of an X-Small frame size. This geometry results in a fat bike that rides like a trail bike. It is stable, steers well in loose conditions, and still remains nimble and agile despite the massive wheels and tires. A low bottom bracket height is also key, keeping the rider's center of gravity low, and making dabbing, dismounting, and remounting easier.
27.5 x 4.0" Wheel & Tire Size
Beargrease rolls on 27.5 x 3.8" wheels and tires. For groomed snow or dirt, the increase in diameter provides increased rollover, a longer contact patch, and the flotation of a 4.0" tire without added rolling resistance.
Kingpin Deluxe Fork
Featuring a full carbon design, the Kingpin Deluxe Fork is lightweight and durable, and features an amazing array of accessory bosses to help you make the most of your Beargrease fat bike:
- Dual sets of Three-Pack bosses on each leg accept bottle cages or our Anything Cage accessory
- Lowrider mounts work with our Down Under front rack for a traditional touring setup
- Internal dynamo hub wire routing keeps the front end clean for those upgrading to dyno hubs
- 150 x 15mm thru-axle design boosts stiffness and aids in solid tracking on the trail
