Beargrease Geometry

A 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" Wheel & Tire Size

Beargrease rolls on 27.5 x 3.8" 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

Kingpin Deluxe Fork

Featuring a full carbon design, the Kingpin Deluxe Fork is lightweight and durable, and features an amazing array of accessory mounts to help you make the most of your Beargrease: Dual sets of Three-Pack mounts 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.

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: 197 mm 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
