Salsa Beargrease Carbon X01 Eagle
$4,699.00
Beargrease is constructed with a high-modulus carbon fiber frame. This material offers improved stiffness, better vibration damping, excellent durability, and weight savings compared to other frame materials. Its carefully designed geometry results in a fat bike that rides like a trail bike—it’s stable, steers well in loose conditions, and 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. 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 5" tire without the added rolling resistance. It’s also compatible with 26" and 29" wheels for dialing in the fit or terrain-dependent performance. The Beargrease Carbon frame features fully sleeved internal cable routing. This improves shifting performance in poor conditions, increases time between maintenance intervals, and makes running new cables and housing a breeze. It’s designed for the best drivetrain performance while maintaining narrow fat bike crank arms for less knee stress, with rider-friendly narrow Q-Factor cranks, a 1x optimized frame design, and room for up to a 32t max chainring. Beargrease Carbon features numerous accessory mounts, including toptube bosses for a Salsa EXP Series Toptube Bag (sold separately), 1 – 2 water bottle mounts inside the frame triangle (depending on frame size), and an accessory mount underneath the downtube. Plus, it’s compatible with dropper seatposts for true trail bike riding experiences. Featuring a full carbon design, the Kingpin Deluxe Fork is lightweight and durable and provides an amazing array of accessory bosses to help you make the most of your 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, and internal dynamo hub wire routing keeps the front end clean for those upgrading to dyno hubs. Beargrease Carbon X01 Eagle doesn’t just roll over anything, it flies. This is the ultimate fat bike designed to convert strength and determination into speed. It is built with a carbon frame, 80mm Mulefut SL rims paired with DT Swiss 350 hubs, and a SRAM Eagle X01 drivetrain for unrivaled performance.

Salsa Mukluk Carbon NX Eagle
$3,149.00
Mukluk rolls on 26 x 4.8" wheels and tires—this huge tire delivers massive traction, stability, and optimum flotation on soft surfaces such as ungroomed snow or loose sand. The frame is constructed of high-modulus carbon fiber, which offers improved stiffness, better vibration damping, excellent durability, and weight savings compared to other frame materials. Mukluk’s geometry works extremely well in all conditions, 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 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. Additional features that increase Mukluk’s versatility include stealth dropper post routing, rear rack compatibility, and numerous accessory mounts: toptube bosses for a Salsa EXP Series Toptube Bag (sold separately), two water bottle mounts inside the front triangle, and one accessory mount underneath the downtube. It’s got full-length housing that improves shifting performance in poor conditions, and room for multiple wheel/tire combinations, allowing you to dial in your fit or the bike's performance to a specific terrain. Mukluk Carbon NX Eagle pairs our carbon frame with the Kingpin fork and a SRAM NX Eagle drivetrain to offer incredibly precise performance. SUN Ringle Mulfut SL 80 rims are wrapped in 45NRTH Dillinger 5 tires, for a voluminous combination that manages to keep the weight down, too. It’s a combination that is light and responsive when you demand the best of the best.

Surly Big Fat Dummy
$3,025.00
The Big Fat Dummy is a long tail cargo bike that took a few too many doses of growth hormones. At first glance, you might say that Surly just put bigger tires on a Big Dummy. But if you said that, you'd actually be very wrong so just… don't. Think of Big Fat Dummy as more of a second or third cousin to Big Dummy rather than a brother. They share some of the same DNA and look sort of similar, but they're two very different bikes and really only interact when they both reach for the potato salad spoon at that family reunion that no one really wants to be at anyway. Now that that's out of the way, let's get down to the nitty gritty of what makes this hulking beast of a bike tick. Surly's goal with designing a cargo bike around fat tires was to create the most stable, stiff, and traction-laden ride possible while hauling a ton of stuff. Big Fat Dummy has a longer toptube and slacker headtube than its more svelt cousin giving it a nice, predictable, and stable ride. They also used thinner, lighter tubing to construct its cargo area so while it's an overall burlier bike, there's not much difference in weight. Big Fat Dummy accepts either 10mm or 12mm axles in the rear with a spacing of 190/197mm. That big ol' spacing equates to one thing: tire clearance for days. Big Fat Dummy maxes out at a massive 26 x 5.25" tire.* While that large of a tire provides the most traction and stability a bike can possibly offer, it's also a lot of rubber to push and might not be for everybody. Luckily, Big Fat Dummy is also a blast to ride with 3" tires too. It uses the same 100mm suspension-corrected fork as the Wednesday, meaning if you want to add a little squishy squishy to your ride, you can throw a Bluto on and let ‘er rip. If you intend to carry a passenger on your Big Fat Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility. All Big Fat Dummy framesets and bikes ship with a Dummy deck, rails, bags, and the aforementioned Dummy Rail Collars so you can immediately start hauling cargo — human or otherwise. Big Fat Dummy is ready and willing to carry all sorts of crap — literally. It's already in use on an organic farm in Ecuador so it's likely that it's hauled some form of manure by now. *Using a 26 x 5.25" tire will cause some drivetrain limitations.

Salsa Mukluk Deore 11
$1,599.00
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.
