Fat Bikes

The Heyday! Advent is a machine made with adventure in mind. 26 x 4.6" tires have no trouble rolling over loose terrain or tracking through overgrown paths. The aluminum frame blends durability and weight savings with stable geometry for roaming far and wide. And Heyday!'s versatility is unmatched: Alternator 2.0 dropouts allow for multiple drivetrain setups; cargo mounts let you load up for a day or a week; your wheel and tire options also include 27.5 fat and 29+. All this, paired with microSHIFT's trusty Advent wide-range 9-speed drivetrain, will remove "unrideable" from your vocabulary.

ALL SEASON EVOLUTION Balanced weight distribution for maximum traction and a powerful pedaling position keep the Bigfoot 3 charging forward all year. The redesigned Bigfoot elevates fat bike performance to downright fun, anywhere, anytime. The confident, aggressive handling tracks precisely where you want on a descent or technical trail, and the simple one-by drivetrain offers reliable, simple shifts with gloved hands. With maximum traction in the most extreme riding conditions imaginable, Bigfoot claws its way up, and the finely tuned steering geometry and massive tires provide confident, aggressive handling to rip back down. The Bigfoot excels in all-season weather and extreme terrain to make every ride big fun. PROGRESSIVE DESIGN Built from the powder-up with our holistic approach to fit & geometry. A combination of longer reach, slack head tube angle and steep seat tube angle gives every Bigfoot a powerful pedal position, increased climbing traction and added control when descending. FAT’S WHERE IT’S AT 75mm wide 27.5” rims and frame clearance for up to 4.6" tires to put more rubber onto whatever surface you're riding and allow for lower pressures and greater traction. FRAME FEATURES Evolved, thoughtful details make it even better. Generous standover clearance and extra stiffness provided by 12x197mm thru-axles and internally routed cables make the Bigfoot’s aluminum frame ideal for extreme terrain. WINTER RIDER Optimized for the cold, capable year-round. All models feature disc brakes with DOT fluid or cable actuation for consistent performance over varying temperatures. When included, dropper posts are spec’d for reliable cold weather performance. MULTI-FUNCTIONAL Frame details add versatility. Rack mounts in the rear, bottle mounts above and beneath the down tube and triple mounts on the fork give you the option of running a barebones setup or loading up for a massive excursion. STANDOVER HEIGHT Top tube clearance is critical in fat biking. Getting off the pedals in deep snow requires lots of space over the top tube. Bigfoot strikes a perfect balance between max clearance and making space for a frame bag in the front triangle.

Why follow tracks when you can make your own? Experience the "Foot out, flat out" fun of fat biking in any seasons. Whether you're tackling fresh snow pack or drifty sand dunes for days, the new Yukon will keep you rallying your favorite terrain in a whole new way.

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.
