Surly Big Dummy Frameset
$1,050.00
Big Dummy is a long-tail cargo bike, which means that not only can you haul a serious amount of cargo, different accessories can be added to your Big Dummy frame and deck depending on what you want to carry. Being a dedicated single-piece frame, instead of an add-on to an existing bike, it’s stiffer and resistant to torsional flex, which provides a better ride and longer lasting frame than long-tail add-ons. Like all Surly's frames, it’s made of size specific, 4130 CroMoly steel – a tube set engineered for cargo that sports lots of little touches that you’ve come to love in a Surly, like clearance for big tires and the use of common component sizes. Figure on being able to carry about 200 pounds (90kg) of cargo. The load weight, and how it’s loaded, will affect the handling somewhat. Also, plan on using gears, especially as cargo weight increases. This may seem obvious, but as you get comfy with it, you will use your full range of gears as never before. The included Dummy Rail Collars provide a secondary retention system for the rack, as well as stiffen the rack system so you can safely carry a passenger.
Specialized S-Works Epic Frameset
$5,999.99
Don't worry, we get it...your training buddies all think you're a bit "particular". You may or may not have stockpiled your favorite grips just in case they ever get replaced by a new model. Perhaps your trailside toolbox would make a quality control engineer blush. Whatever the case, you won't find any judgment here. Instead, the endlessly engineered S-Works Epic Frameset is here for you to let your discerning tastes run wild. We sweated every last detail when designing the S-Works frame, from an endlessly refined layup schedule that re-examined every last ply of FACT 12m carbon to optimize weight savings and ride dynamics, to the weight-shedding carbon shock link, all so that you focus on the rest, knowing that you're starting with the most capable canvas in the world. True to form, the latest Epic continues the tradition, taking advantage of the most efficient Brain suspension we've ever created to ensure it's always on a first-name-basis with fast. Re-engineered hand-in-hand with the new Epic, the latest BRAIN design resets the expectation for efficiency, employing a new race-tuned pedaling platform to ensure every watt possible is translated into forward motion, while handily soaking up momentum-killing chatter and big hits alike, all more smoothly than ever. Perfectly matched to the frame's BRAIN system, the S-Works Epic frameset's Position-Sensitive BRAIN fork benefits from RockShox's latest SID Ulitmate SL chassis for next-level steering stiffness that still manages to keep the gram count to a minimum. - If speed could talk, it'd introduce itself as the all-new S-Works Epic frame. Offering 100-millimeters of brilliantly efficient Brain-controlled travel, the S-Work Epic increases rear-triangle stiffness for peerless power transfer, while the use of FACT 12m carbon, a dedicated layup, and a full carbon shock link also make it the lightest full-suspension frame we've ever created, all while offering the most capable handling in an Epic yet. Nice to meet you, speed. - Pairing 100 millimeters of the most efficient travel on earth with RockShox's svelte-yet-stiff SID SL Ultimate chassis, the RockShox SID SL Ultimate BRAIN fork serves as the pinnacle of XC-race suspension perfection.

Specialized S-Works S-Works Enduro Frameset
$3,399.99
This is the bike that defines the very genre that bears its name, the S-Works Enduro climbs with utmost efficiency yet stays calm on even the gnarliest descents. It features a bomber, yet lightweight carbon frame that blissfully tackles the kind of terrain that chews up and spits out lesser bikes. ASTONISHINGLY FAST, UP AND DOWN THE TRAIL Stomp on the pedals and the new Enduro accelerates far quicker than you'd expect possible from a downhill bruiser. To start, we increased anti-squat, so the suspension better-resists pedal bob. Then, to further its efficiency, we re-directed the angle of the chainstay and upper shock linkages for a much more efficient design. The end result? Less bobbing, more speed. FAST STARTS WITH FIT Fast and fit aren't mutually exclusive, which is why the progressive geometry of the Enduro has been designed for going up and down. To start, seat tubes and stack heights don't grow massively between sizes, meaning you can now pick a frame size based on both your height and your riding style. Pair this new sizing style with a slacker head angle, longer reach, and steeper seat tube across the line, and you're left with a quicker and more capable steed, no matter the size. INCREDIBLY CAPABLE If the Enduro looks like its sibling, the Demo, it's because they share plenty of downhill DNA. A more-rearward axle path reduces wheel hang-up on big impacts. A low- and forward-positioned shock keeps it planted and confident-feeling at high speeds. And balanced chassis stiffness helps the front-end steer precisely and keeps the rear-end tracking like it's on rails. Add it all up and you have a bike that laughs in the face of the steepest, rockiest trails.

$2,399.99 - $2,400.00

TRAIL-TAMING TRAVEL All the travel in the world is useless without the proper kinematics, which is why we kept it at the forefront of the new Stumpjumper design. With the learnings from the suspension design on the Enduro, and over 1,000 hours of field and suspension lab development, we've greatly improved the pedaling performance, all while creating the capable, efficient, lively feelings that you long for. We increased anti-squat, so the suspension better-resists pedal bob, and then, we further-improved bump performance on square-edge hits. Bottom line? The all-new Stumpjumper descends with complete control yet climbs with ease. PROGRESSIVE GEOMETRY The S-Sizing geometry of the new Stumpjumper hits the progressive sweet spot. Long, low, slack, a short offset fork, a steeper seat tube angle—they're all the talk of the town because they make your ride better. With Flip Chip adjustability you’re able to further fine-tune your fit, ensuring that your new Stumpjumper performs flawlessly on whatever terrain you choose.
Specialized Stumpjumper Comp Alloy

Turns out, you can have your cake and eat it too with the new Stumpjumper. PROGRESSIVE GEOMETRY The S-Sizing geometry of the new Stumpjumper hits the progressive sweet spot.
