Fat Bikes

Beargrease is our fat tire bike built to go faster than you knew fat tire bikes could go. The super-light frame and fork and the sure-footed rollover of 27.5 x 4.0" wheels and tires cover challenging terrain quickly. Versatile frame and fork mounts let you carry everything you need for the backcountry. Test yourself in a snowy endurance race or pack your camping gear and embark on a long-distance overnight bike trip.

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. Beargrease Geometry 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

The Mukluk is Salsa's most versatile fat bike, designed and engineered to excel in a wide variety of conditions. The frame utilizes 197mm rear spacing to accommodate up to 5" tires, and the 100mm threaded bottom bracket allows a wide range of crank (Q-factor) choices. Alternator 1.0 dropouts allow for short chainstays and easily support single speed or geared drivetrain options. The Mukluk can do it all.

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.

The All-Around Fat Bike Wednesday sits in the middle of our Trail category, but don't let that fool you into thinking that's its only use. With Wednesday, we borrowed elements from some of our Trail and Touring models to create a versatile fat tire trail bike that can truly handle anything you want to attempt. If you do an equal amount of off-road touring as you do hitting trails, Wednesday's ability to play both parts equally will suit you well. Or, if you're looking for a fat bike and don't need the fattest tires on the market, Wednesday's 26 x 4.6" tire clearance is just the ticket. - Modern mountain standards: stealth dropper post routing, 44mm headtube, suspension correction, front and rear thru-axles - Full suite of useful braze-ons: front and rear racks, multiple sets of three-pack mounts, fenders - Full-forward, short chainstay position: 26 x 3.8" tires on 80mm rims; full-rearward, longer chainstay position: 26 x 4.6" tires on an 80mm rim Specs: - Rear Dropout Configuration: Horizontal slotted with optional vertical dumpout - Rear Hub Spacing: 12 x 177mm (Surly axle included); 10 x 170mm with Surly 10/12 Adapter Washers (not included) - Front Hub Spacing: 15 x 150mm (Surly axle included) - Rear Brake: Disc - 51mm I.S.

A good adventure partner is reliable, covers ground at your pace, helps shoulder the load, and gives you the confidence to keep going when the trail looks tough (or disappears entirely). Mukluk checks all the boxes with Alternator dropouts, a lightweight aluminum frame, plenty of gear mounts, and stable geometry. We'll let you two start planning. 6066-T6 Aluminum Frame Top-shelf, double and triple-butted, heat-treated 6066-T6 aluminum tubing is used throughout the frame. This 6000-series aluminum has better strength and fatigue characteristics than 6061 and 7000-series aluminum, allowing for a stronger and lighter overall frame. Additionally, the tubing is strategically shaped and formed for additional stiffness and strength optimization in key stress areas. Mukluk Geometry Mukluk's geometry works extremely well in all conditions and use cases, whether it be riding groomed singletrack at your local trail, exploring a beach coastline, or embarking across the wild frozen expanses of Alaska. At its core, we use the shortest chainstay possible with a headtube angle and fork offset that place the rider's center of gravity further over the rear wheel. This location and combination of front and rear center is key to getting a fat bike that is stable, steers well in loose conditions, and still feels nimble and agile despite the massive wheels and tires. A low bottom bracket is also key to keep the rider's center of gravity low and to make dabbing, dismounting, and remounting easier. 26 x 4.6" Wheel & Tire Size Mukluk rolls on 26 x 4.6" tires on 80mm rims. This huge tire delivers massive traction, stability, and optimum flotation on soft surfaces such as ungroomed snow or loose sand. Bearpaw Carbon Fork This full-carbon fork features a 150 x 15mm thru-axle that boosts stiffness and improves steering precision. The fork also features our Three-Pack mounts for accessorizing with Anything Cages or water bottle cages.

The Mukluk is Salsa's most versatile fat bike, designed and engineered to excel in a wide variety of conditions. The frame utilizes 197mm rear spacing to accommodate up to 5" tires, and the 100mm threaded bottom bracket allows a wide range of crank (Q-factor) choices.

"Fast" and "fat bike" may seem mutually exclusive until you've ridden Beargrease. Its 27.5 x 4.0" wheel and tire combo offer better rollover than your standard fat bike, and Beargrease's carbon fiber frameset is lightweight yet stiff for excellent power transfer. But, being svelte doesn't mean sacrificing utility—ample cargo-mounting points make this the best fat bike for light-and-speedy adventures.
