If fast and flowy trails are calling your name, the Pique 29 is begging to come along. This cross-country bike climbs and descends with confidence-inspiring stability and speed. Durable The sturdy ALUXX SL-Grade Aluminum frame is tough and dependable for your most epic adventures. Capable 29-inch wheels easily roll over small obstacles, while 100mm of Maestro suspension – tuned for women, by women – help absorb rougher trail. Stable An integrated dropper seatpost and clearance for up to 2.4-inch tires means you can confidently ride moderately technical terrain.

The redesigned Cutthroat drop-bar mountain bike and gravel frameset offers more stability and compliance in a package that’s equally at home bikepacking on remote doubletrack, taking the occasional singletrack shortcut, or conquering a gravel race.

Breaking the Mold with a 29er Bike As the first "plus" bike to hit the market, Krampus changed the way many people approach trail riding. It's shown people the light of how high volume, large diameter tires can vastly improve the ride experience. It's also done a bang-up job dispelling the myth that big tires make you slow. Krampus is kind of like the opposite of a mullet: long in the front and short in the rear. With a long toptube and compact chainstays, it takes trail-shredding abilities to the next level. A mullet may be business in the front, party in the back but Krampus makes partying its business. "Lean back, hang on, and ride that wild horse." -Thor - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles, suspension corrected fork - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Clearance for 29" x 3" tires

The Woo continues to be one beloved fat beast! Its ability to carry massive amounts of gear with its three-pack cage mounts aboard its carbon disc fork make it a sand and snow bike packing favorite. With geometry derived from the Honzo, ultra-powerful hydraulic disc brakes and a 12-speed drivetrain, you're in complete control whether climbing up snowy mountains or surfing sandy descents. 4.8" tires ensure that rolling over anything is possible. We bet you'll catch yourself "Wooing" your way down your favorite trails. ONA 6061 ALUMINUM Kona 7005 and 6061 Aluminum alloys are used extensively throughout our fleet of mountain and asphalt bicycles. A tough, durable, light alloy, both Kona 7005 and 6061 deliver fantastic, reliable performance that lasts for thousands of rides. Much of our 7005/6061 tubing is butted and/or formed, meaning the tubing's wall thickness can be increased or decreased, as well as shaped, so we can fine-tune a particular frame's strength and ride characteristics depending on its intended application. INTERNAL HEADSET Bearing cups are actually pressed into the frame and are easily removable. An internal headset also reduces stack height, so the height of the stem and bars are more adjustable, giving the rider the best fit possible. TAPERED HEAD TUBE More girth at the bottom of the head tube better distributes shock force, prolonging the bearing life of the headset itself and eliminating brake shudder, while providing confident steering performance. The inherent strength of its triangular design also means a stronger steering position and improved balance, giving the rider more control in rough terrain. A zero-stack, tapered head tube also puts strength where the load is going—into the lower headset cup—maximizing bearing durability where it's needed. TUBELESS COMPATIBLE RIMS Tubeless rims allow for tires with more puncture resistance; the ability to run lower tire pressure, which provides better tire grip on the trail; lower rolling resistance; and weight savings over traditional tube and tire systems.

Alternator 1.0 dropouts allow for short chainstays and easily support single speed or geared drivetrain options. The Mukluk can do it all. Mukluk rolls on 26 x 4.6" wheels and tires—this huge tire delivers massive traction, stability, and optimum flotation on soft surfaces such as ungroomed snow or loose sand., 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.
