Beargrease was the industry's first carbon fat bike, and its pioneering spirit is evident in the light and nimble carbon frameset with plenty of cargo-mounting options. The 27.5 fat bike platform improves rollover and reduces rolling resistance—perfect when you're trying to keep your speed up on a groomed race course or singletrack. The 1 x 11 Shimano Deore drivetrain is a smooth-shifting workhorse that brings reliable performance wherever you take it.
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
