Specialized Stumpjumper EVO Pro
$7,499.99
The Stumpjumper EVO Pro is a testament to full-gas trail performance. With an all-new design, from its S-Sizing geometry with an adjustable head tube angle, to its 150mm of shred-ready travel, this thing is a full-on ripper. And to top it off, it's build has been hand-picked to keep overall weight low and stoke high. Fox Factory suspension? Check. Carbon 30mm-wide wheels? Check. XO1 Eagle drivetrain? Oh, yeah. With the Stumpjumper EVO Pro, you get all the goodies at a more palatable price. 150MM OF 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 EVO design. With the learnings from the suspension design on the Demo and Enduro, and practically countless hours of field and suspension lab development, we've not only improved the pedaling performance of the Stumpjumper, but we've made it more capable, agile, and lively. We increased anti-squat, so the suspension better-resists pedal bob and then, we further-improved bump performance on square-edge hits. Bottom line? This thing shreds trails not legs. ADJUSTABLE GEOMETRY The S-Sizing geometry of the new Stumpjumper EVO is our most progressive yet. 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. But the perfect geometry is different for different riders, which is why the geo on the new Stumpjumper EVO is fully adjustable with six different settings. Not only are you able to adjust the BB height by 10mm, but you can adjust your head tube by two-degrees. RIDER-FIRST ENGINEERED Rider-First Engineered frames use a size-specific approach to ride characteristics that ensures every frame performs flawlessly. So, whether you're a Grom riding an S1, or in need of the lengthy S6, you'll experience the same ride characteristics—on-rail cornering and balanced front and rear stiffness, all at the lightest-possible weight. SWAT When we introduced the SWAT door on the Stumpjumper in 2016, we increased pocket space, and added room for those "oh s**t" pumps and flat accessories. With the new Stumpjumper, we've kept those same design hallmarks, but have increased the volume and added a SWAT Bladder, that gives you an extra 22oz of water hidden in your downtube. Yes, it's the same size as a small bottle.

Specialized Epic EVO
$3,799.99 - $3,800.00
Remember when cross country didn't always involve a starting gun? So do we. And, while it'll never turn down a number plate, Epic EVO is well-acquainted with the fact that the next ridgeline makes a perfectly good finish line too, offering an incredible combination of pedaling efficiency and impressive trail-taming capability to get you there faster. p>While the Epic EVO sees a seemingly modest 20-millimeter increase in suspension travel up front over its Epic stablemate and just 10-millimeters out back, we've worked overtime to make sure it's been implemented in a way that'll have you saying 'Whoa!' as soon as you hit your first stretch of singletrack. Meticulously engineered to retain as much of the Epic's standard-setting efficiency as possible, the EVO's new suspension kinematics work in concert with our Rx XC shock tune to ensure you're able to make the absolute most out of every inch of travel on tap, while still offering increased anti-squat characteristics for improved pedaling efficiency. With plenty of practice at staying ahead of the curve, the Epic EVO now lays claim to the most capable iteration of our Progressive XC Geometry ever to grace an Epic. It's also more versatile than ever thanks to a new flip chip-equipped rear end that allows riders to adjust headtube angle and bottom bracket height to easily customize the Epic EVO's handling characteristics. Epic EVO's flyweight FACT 11m carbon frame features heavy-hitting Shimano components and RockShox suspension for a package tailor-made for making miles disappear faster than ever. - Flip It To Rip It: Tune the ride of the Epic EVO's FACT 11m carbon frame to match your preferred handling characteristics with flip-chip simplicity that allows riders to steepen the EVO's headtube angle by half a degree while raising the bottom bracket height by six millimeters. - Shimano's SLX shifting has always been the benchmark for affordable high performance, and the latest M7100 series simply raises it even further. - The Reba RL doles out travel with a steady hand courtesy of RockShox's Motion Control damper, while SoloAir adjustability makes dialing in suspension performance a breeze.
Santa Cruz Hightower C S
$5,749.00
Our greatest hits compiled into one bike—just hit play. If ever a bike resembled your most cherished mix tape compilation, the Hightower is it. Featuring our lower-link mounted shock design, updated, adjustable geometry, this "Engineering Best Of..." assembles some of our biggest design pleasers into one belter of a road-trip companion. The Hightower has been a does-it-all-well trail bike since its inception. Hightower excels when the route covers 'all points in between,' and descents come courtesy of some big-ass climbs. The VPP suspension’s lower-link-mounted shock creates a nearly linear leverage curve, meaning it mops up bumps of all sizes while maintaining progressivity! 140mm of rear travel complemented by a 150mm front end gives Hightower just a bit more front and rear travel over the first-generation model. Combined with a slacker 65-degree head tube angle, the Hightower still sits squarely in the Goldilocks zone, but with a touch more "Get me out of here!" capability when the porridge gets too hot! Balancing stiffness and weight savings in all the right places is a hallmark of all Santa Cruz carbon frames and the Hightower flies the flag yet higher. The advanced composite chassis tracks well across all trail surfaces, holds a line, and is reactive to rider directions while isolating pedal-influenced inputs. The Hightower also has a bonus disc to heighten the experience—the flip chip. In the High setting, the BB height is a little higher for those tricky tech trails and/or when Plus-sized tires are required. In the Low position, the shock rate is more progressive to provide additional bottom-out resistance. Whatever mood you’re in, the tone of the Hightower can be adapted to meet your individual taste. And speaking of taste, there’s a room for a water bottle inside the main frame and a threaded BB for convenience. There's refined cable routing for better shifting performance, simpler installation, and no cable rub. On top of that, there’s a tailgate shuttle guard, downtube protector, shock fender, and noise-canceling chainstay protector keeping things quiet. The lifetime frame warranty, lifetime pivot bearing replacement policy, and lifetime guarantee on the optional Reserve carbon wheels assures you that the Hightower will keep delivering the hits for years to come. - Carbon C 29/27+ 145mm Travel VPP frame - FOX 36 Float Performance 150mm fork - RockShox Super Deluxe Select+ shock - SRAM GX Eagle drivetrain - RaceFace AR Offset 30 rims/DT 370 hubs - RockShox Reverb Stealth dropper

Specialized Men's Stumpjumper ST Expert 29
$5,000.00
Trail bikes can't usually 'shred the gnarly stuff' and 'climb with your XC buddies,' but we're confident in saying that the Stumpjumper Expert ST 29 is totally capable of both. It combines precise handling, perfect suspension kinematics, and a complete abandon of proprietary nonsense with a slightly steeper geometry, less travel (130mm front/120mm rear), and 29-inch wheels to make it a true 'do-it-all' trail bike. Our design goal for the new Stumpjumper was simple—build the ultimate trail bike, one that feels telepathic. And it turns out that this feeling all comes down to stiffness. Think of it this way: when the frame's telling your hands one thing and your feet another, your brain gets confused with the imbalance and the bike feels unstable. In order to fix this, we had to get to work on dialing-in the materials, shapes, and the layout. We started by creating our own mountain-specific stiffness test, and then we looked at the layout with Finite Element Analysis (FEA) to see where we could get the biggest stiffness improvements. This led to a big discovery: The Large and X-Large frames needed more front-end stiffness while the Smalls and Mediums were just fine. We were able to create a frame design that was 20% more efficient. And in the end, this proved to be one of the lightest trail frames on the market, today. When designing the frame with the stiffness targets being a main goal, we developed a radical new sidearm design. The front-end and rear-end are connected at three points, and the sidearm helps keep all these points super stiff and connected, all while taking about 100 grams out of the rear-end. More explicitly, this minimizes frame flex when the rear suspension is active. We continued down the suspension path with a custom Rx Trail Tune on both the fork and rear shock. Suspension performance is highly dependent on frame, wheel, and rider size, so we use our Rx Tune to get each bike to land in the middle of the adjustment spectrum, and this gives you the biggest possible range to fine-tune your ride. Another focal point of the tune was matching the suspension characteristics between wheel sizes—we developed a specific Rx Tune for each platform. So, no matter what wheel size you prefer, you'll get perfectly linear suspension. Steps were also taken to make this bike easy to live with. Threaded bottom brackets make a triumphant return, and we made room for up to a 3.0" tire. You're also free to run whatever aftermarket rear shock you want since we're using standard metric shocks. We revamped the SWAT box, too, making it sleeker, lighter, and with more volume. And customization is furthered with a Flip Chip that lets you to dial-in your Stumpy to your riding style. Switch it from High to Low and it drops your bottom bracket 6mm and slackens the head tube by half-a-degree. Little details also jump out to surprise you, like a newly designed ribbed chainstay protector that makes chain slap a thing of the past and nearly silences the drivetrain. Lastly, we seriously couldn't make cable routing any easier on carbon models. Full tubes can be found throughout the carbon frame, so all you have to do is push the cable and it'll come out the other end. No more lazy loop, hidden stashes of magnets, pokey spokes, or pillows to cry in. For the build, you get a solid components package with a full SRAM GX1 Eagle drivetrain, SRAM Guide R disc brakes, RockShox Pike RC fork and a Deluxe RT3 rear shock (130/120mm of travel respectively), and Roval Traverse Carbon 29 wheels. - The Stumpjumper ST's asymmetrical, FACT 11m carbon fiber construction is lightweight, stiff, and ready for technical climbs and rowdy descents. It's built off of our 29 Trail Geometry, so it's both capable and comfortable. And with SWAT integration in the down tube, a threaded BB, easy cable routing, and a brand new chain silencer, it's ready for anything the trail, or you, throw at it. - With three different compression adjustments—open/pedal/lock—incredible damping performance, and our Rx Trail Tune, the RockShox Deluxe RT3 perfectly complements the Stumpjumper. - RockShox's Pike is known for its trail performance, and the RC found here has stiff stanchions, a Charger damper, and plenty of sensitivity.

Our A1 Premium Aluminum frame features a tapered head tube to reinforce the front end against hard landings, and forged horizontal dropouts with integrated chain tensioners to ensure your rear wheel stays solidly in place.
Specialized S-Works Epic Hardtail Frameset - LTD
$2,950.00
There's not much that matches the feeling of powering up a pitch on a featherweight bike, and we designed the new S-Works Epic Hardtail frame with this in mind. It's less than 900 grams, exceptionally stiff, and it features a Rider First Engineered design. It's the perfect jumping off point to begin creating your dream build. Over the last decade, cross country racing has evolved into a completely different animal—the courses are rowdier, more technical, and overall, they're inherently different. Because of this, we realized that the best bike for the job needs to not only be lightweight and stiff but also be able to descend and climb with equal prowess. Determining the best geometry was the easier of the two, as we took our current XC race geo and added some trail DNA to the mix. This equates to a longer top tube, a shortened head tube, and a slacked-out front end, the result of which is a tremendous increase in downhill stability, plus a wider fit range. And just as importantly, this doesn't require any sacrifice of climbing proficiency. The weight aspect was more complicated, though. We were posed with the question, "How do you take weight out of something that's already so light?" But the answer was relatively obvious: you get the best mountain bike engineers together in one room and let the magic come out. Up until now, there were two ways to lighten up a frame—use less of the same grade of carbon or use less of a higher-grade carbon. Option one is never a viable solution as it sacrifices stiffness and strength, two attributes that shouldn't be tampered with. And while we did end up using option two, we weren't content with the amount of weight we could cut out by just using a different grade of carbon. So how else do you cut weight? Well, we began looking at our layup schedules to see if they could be improved, which shed light on a new discovery—layup inefficiencies. Beginning with our Rider-First Engineered frame technology, each size Epic Hardtail is specifically tailored to size—every carbon layup and tube are exclusively selected based upon hundreds of hours of collected ride data. What does this mean for you? It not only creates the optimal balance of rigidity, weight, and responsiveness across every frame size, but it led us to the discovery of how to save weight through the studying of the layup. Through extensive layup studies, we made the discovery that, by further controlling the construction and layup schedules, we could drastically decrease weight, all while maintaining the ride characteristics that you'd expect from a top-level XC race bike. With this discovery, each frame now features complex cut carbon plys that allow difficult junctions to be covered with less overlap. And while this does complicate the carbon frame puzzle by adding more pieces to the mix, it allows us to design and place them more intelligently. The result of this is a lighter frame, stronger junctions, and a drastic increase in stiffness. We then took the weight savings one step further by using Japanese military ballistic-grade carbon, which we now call 12m, to create the lightest mountain bike we've ever made. How much lighter of a frame, you ask? Less than 900 grams for a size Large frame—the same weight as a full 24oz Purist water bottle. - To provide the optimal blend of stiffness, crazy light weight, and strength, we constructed the frame from our S-Works FACT 12m carbon fiber. And when combined with our XC 29 Geometry, this Epic is guaranteed to deliver uncompromising, blistering speed and agile handling come race day—no matter the course.
Specialized Chisel Frame
$999.99 - $1,000.00
The all-new Chisel has been purpose-built to tackle modern cross country trails and race courses with the utmost speed. In fact, it shares many of the same modern features as its Epic Hardtail sibling, but in a more budget-friendly package, making it the most efficient and capable alloy hardtail out there. And with this frame option, you can build your new Chisel exactly how you like. Top-end build for a durable XC shredder? Oh, yeah. Or maybe a budget-friendly one that you can upgrade later? Easy. The Chisel frame is the perfect canvas to start painting your new path to XC racing. - The Chisel's all-new frame utilizes our D'Aluisio Smartweld technology that moves the hydroformed tube joints away from the areas of the highest stress, making the finished frame's balance of strength, rigidity, and weight more pronounced than any alloy frame in history.

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.
