2025 Salsa Beargrease C XT - Indigo

Beargrease C XT blends the DNA of a fat-tire bike and a trail bike for a ride that devours groomed snow trails and more. The carbon frame and fork are lightweight and pair perfectly with Beargrease's nimble geometry. Its 27.5 x 4.0" tires are an unstoppable combo of rollover and float that open up new terrain. Mounts for bags, bottles, and racks make it easy to bring extra layers, snacks, or even camping gear - whatever you need for extended rides. Shimano's time-tested XT 1 x 12 drivetrain has tons of gear range on tap, making this one of the best fat-tire bikes for both racing and roaming.

Beargrease Geometry

Completely redesigned frame and fork for 2019. 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 a new XS 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" Wheel & Tire Size

Beargrease rolls on 27.5 x 4" wheels and tires. For groomed snow or dirt, the increase in diameter provides increased rollover, a longer contact patch, and the flotation of a 5" tire without the 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
