Mountain Frames

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. - 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 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. "Any day of the week's a great day to ride a Wednesday." - 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.

Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. Your BMX Bike All Grown Up Lowside is like the grownup version of the bike you rode when you were a kid and still had hopes and dreams and some semblance of ambition. It's just as happy riding singletrack as it is parked outside your favorite drinking establishment. Lowside is a single speed mountain bike. Singlespeeding has been a part of Surly's DNA since day one when we launched the 1x1 Rat Ride. After a lot of Homie Fall Fests and more feats of strength than we can recall, we decided to discontinue it a couple years back. Lowside picks up right where the 1x1 left off. "Some have dubbed the Lowside the ultimate pub cruiser." - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Spec'd in alternating years with 26 x 3" or 27.5 x 2.8" tires, the Lowside remains capable of running either option

Karate Monkey is a highly versatile trail bike that plays the part of 29er and 27.5+ equally well. Karate Monkey delivers a resilient, lively ride on all sorts of gnarly terrain. Its frame is a highly-versatile canvas for whatever dirty masterpiece your brain cooks up. According to our computing machine (Thor) it can be set up in approximately 487 different configurations. Originally designed as a 29er (and the frame that helped spark the 29" wheel movement), the latest Karate Monkey is designed to perform just as admirably as a 27.5+ rig as well. This allows you to pick your poison — provided your poison is having a really great time while permanently donning a huge grin, of course. - 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 2.5" or 27.5" x 3" tires

Meet the bike in between nothing. Leaving no rider wanting. Master of the climb, the bomb, the rail, and the air. The utterly unequivocal. The rule crusher. The trend buster. No rig can rule all, but this one can absolutely rule. The mountain bike. TRAIL BIKE? YES, AND... This is the mountain bike you reach for when the trail is untamed and unrelenting, in both directions. "Trail bike" is a term that gets used pretty liberally in the industry, so we designed the SB140 to be even better suited to go deep and find out what's on the other. FEATURES: SWITCH INFINITY. RECALCULATED. Discover the next generation of translating pivot suspension designs. Setting new expectations for kinematics, longevity, sensitivity, and strength. CABLE MANAGEMENT. Internally routed cable tubes with secure closures at entry and exit points eliminate rattles and cable rub. Whether running a mechanical drivetrain and dropper or a wireless setup, cable management is intuitively easy and quiet. THREADED BB. Threaded aluminum bottom bracket shell with integrated ISCG-05 tabs. This critical drivetrain interface is now more durable, cleaner, and easier to service. UNIVERSALLY READY. If a hanger bending crash occurs, the new Yeti models use the Universal Derailleur Hanger (UDH) interface — the industry standard mount for a rear derailleur. The UDH is available in nearly any bike shop, Yeti dealer or not. FULL DROP. As the capability of our bikes continues to increase, so does their ability to run modern-day, full-stroke dropper posts. Our seat tube is shorter to allow for a longer dropper post. Most riders will be able to use 150mm dropper posts on Small frames*, 175mm on Medium frames*, and 200 mm+ dropper posts on L-XXL frames* respectively. *Dependent on actual seat height on specific bike size. REFINDED NEW LOOK. STILL DISTINCTLY YETI. The refined main frame and swingarm silhouette are more than just striking good looks – it's an engineering approach that packages Switch Infinity and shock linkage in a tighter, more efficient frame with added impact clearance. Holistic frame chassis stiffness has increased, along with frame ground clearance. UNPARALLELED FEEL. FOR ALL RIDERS. Every rider deserves a frame feel that's tuned for them, regardless of frame size. Over the course of hundreds of virtual simulation comparisons and back-to-back carbon prototype testing, we've refined our carbon layups to deliver consistent torsional stiffness and flex profiles across all frame sizes. The feel is precise yet compliant while structurally balancing light weight and durability. A SMARTER LEVERAGE RATE. Designed around a relatively linear progression curve, with slightly more progression at the end of the stroke for the added travel of the bike. SB140 Riders get great small bump sensitivity, an incredibly supportive mid-stroke, and a composed, bottomless feel. It's a progression curve that delivers quality full travel capability, for mountain biking. Other bikes might have more progressive curves. The question is, what for? PATENTED COMPACT WISHBONE. Our patented, two-piece wishbone shock extender optimizes leverage rate while pushing the shock forward in the frame. This forward positioning allows for a large range of shock compatibility, decreases stand-over height, reduces shock tab sizes, increases water bottle compatibility, and increases downtube clearance. When it's time for service, shock removal is quick and easy. SPEED METAL. Our new pivot designs use 100% standard-sized cartridge bearings secured with precision-machined floating collet axles. All bearings are pressed into the linkage assembly vs the swingarm or front triangle. MORE COMFORTABLE ON MASSIVE DAYS. Rather than conjuring up a claim to rationalize the vanilla geometry that dominates other "mid-travel" bikes, we asked how the remarkable feel of the SB130 can become even more capable of tackling a wider range of terrain? The result is a size-specific geometry that puts SB140 riders in a more balanced position for extra spicy trails in every direction. 1. FORWARD BIAS POSTURE Give racers the room needed to center them on the bike. 2. FRAME REACH FOR RIPPING Frame reach remains sensibly roomy when running modern short stem lengths, but not ridiculously long to justify a "longer, slacker, lower" claim. 3. SIZE SPECIFIC CHAIN STAYS Chain stay length increases with frame size, ensuring the rear center of the bike is proportionately correct for riders of all sizes (XS-XXL). 4. SIZE SPECIFIC SEAT TUBE ANGLES Riders of all sizes stay in a powerful pedal position with seat tube angles that increase with frame size. This makes the transition from seated to standing easier, especially for taller riders. 5. SLIGHTLY HIGHER STACK A slightly more upright position is more comfortable on big ascents and more capable on big descents. Riders who prefer a more aggressive position can run less stem spacers for a cleaner look.

Begging for your input, chomping to respond. Flick it, pedal it, pump it to the moon. A stoke-making mutation of cun-focused DNA, blinding proof that less can be a whole lot more. Come out to play. You bet your ass the SB135 is still down. Dart. Weave. Drift. There are main lines and race lines. And then there are the completely unexpected lines that require a rider with a different headspace altogether. Riders looking to find the fun love the SB135 for its quick-witted playfulness, agility, and ability to unlock creativity. Rather than waxing poetic about new school geometry numbers, know this: the SB135 isn’t a one-dimensional play bike ­– it’s at home on singletrack and in the alpine, seeking the side hits just the same. Give it input, and the SB135 energetically responds. Features: - Switch Infinity. Recalculated. Discover the next-generation of translating pivot suspension designs. Setting new expectations for kinematics, longevity, sensitivity, and strength. - Clearance for What Counts. Whether you need more room to make shapes or simply want more distance between the bike and yourself, the SB135 has an ultra-low-slung top tube. But we didn’t stop there. To make the best fitting bike for smaller riders, we designed an entirely different frame for the small and extra small sizes. Focused on minimizing stand-over height, maximizing seat postinsertion, and preserving space for a water bottle, we moved the forward shock mount to the downtube, designed an even more compact shock linkage, and made a completely different swing arm, all unique to these two sizes. With the ability to fit riders down to at least 4’11”, the small and extra small SB135s are truly their own engineering feats within the SB135 project. - Cable Management. Internally routed cable tubes with secure closures at entry and exit points eliminate rattles and cable rub. Whether running a mechanical drivetrain and dropper or a wireless setup, cable management is intuitively easy. - Threaded BB. Threaded aluminum bottom bracket shell with integrated ISCG-05 tabs. This critical drivetrain interface is now more durable, cleaner, and easier to service. You asked, and we delivered - Hangerless Interface The Hangerless Interface creates the strongest and most precise shifting with Eagle Transmission. It’s also backward compatible – simply thread in a Universal Derailleur Hanger (UDH) and run your drivetrain of choice. - Full Drop. Full Flight. As the capability of our bikes continues to increase, so does their ability to run modern-day, full-stroke dropper posts. Our seat tube is shorter to allow for longer dropper posts. Most riders will be able to use 150mm dropper posts on X-Small and Small frames*, 175mm on Medium frames*, and 200 mm+ dropper posts on L-XL frames* for airs like this. *Dependent on actual seat height on specific bike size. - Patented Compact Wishbone The wishbone shock extender makes low-slung top tubes even lower, allows us to tune the leverage ratio while maintaining kinematics, and makes shock removal a cinch. It’s driven by an all-new link that nests inside the mainframe, for a stiffer pivot ­­– and a cleaner look. - Speed Metal Gone are the days of pivot bearing on carbon contact. Our new pivot design secures 100% standard-sized cartridge bearings in the frame linkages, attached with precision-machined Floating Collet Axles ­– boosting longevity and reducing tolerance gaps to virtually zero. If you’re the type of rider who forgets the last time you changed your bearings, chances are they’re still running smooth. Also: - 25mm More Downtube Clearance - Hot Lap Waterbottle Clearance on XS Frames - 5 Size Specific Geometries -Floating Collet Pivot Axles Enhance Frame Stiffness and bearing Life - Leverage Rate Making turns go boom isn’t fun with your heels dragging in the dirt. But the inconvenient truth is, progressive curves don’t always help maintain composure. A straighter, more linear progression curve means it's easier to tune shocks to pair with suspension kinematics. So we chose a leverage ratio that provides small bump sensitivity and the right amount of progression to maintain mid-stroke support and bottom-out control, without making it impossible to reach full travel. - Unparalleled Feel. For All Riders. Over the course of hundreds of virtual simulation comparisons and back-to-back carbon prototype testing, we’ve refined our carbon layups to deliver consistent torsional stiffness and flex profiles across all frame sizes. The feel is precise yet compliant while structurally balancing light weight and durability. Geometry Features: - All the Right Angles Responsive and designed to feel like an extension of the rider. - Reach for Movement Feels about right. - Low but not Stupid Low Our lowest BB on a full-suspension bike makes turning a dream. - Steep Seat Tube Angle Are we still talking numbers?

Master of the gnarniverse. Bold claim for some. Fact-checked humility for the SB165. At home outside the tape, beyond the norm. Taken on the trails nobody talks about. Trusted on the lines where mistakes can’t happen. Comfortable with all the chaos. Pleased when you’re puckered. Fearless of your fear. FEATURES: CUT THE TAPE. The rowdiest trails are outside the tape, so we gravity-tested in the lab and toss-tested by Reed Boggs. SECURE IN THE ROUGH. Chainguide ready out of the box. And standard equipment on all SB165 builds. GRAVITY TESTED The SB165 is built tough. The frame meets Yeti DH testing standards, well beyond what others do for a 165mm trail bike. This thing will last for a lifetime, but we gave you a warranty to match just for good measure. LET’ER EAT Chair lift, Shuttle truck or self-shuttle. The SB165 doesn’t discriminate. If you choose to earn your turns, it’s no slouch. ANTI-SQUAT Across our line, we have chosen a relatively flat and high anti-squat curve in the beginning and mid-section of travel where pedaling commonly occurs a.k.a. the pedaling zone. This creates an efficient pedaling platform through your entire pedaling zone, as opposed to one single point. After the pedaling zone, there is an inflection point where the Switch Infinity link moves down, dropping the anti-squat drastically. Riders are typically not pedaling in this zone, so chain forces have less of an effect on the suspension performance. Decoupling of the chain forces allows the suspension to work more efficiently to absorb impacts making the feel of a Yeti distinct. LEVERAGE RATE When seeking to find the outer limits of personal performance, it would be a shame to reach the limit of your bike first. - PROGRESSIVITY: 27.5% NEW SCHOOL GEO FOR NEW SCHOOL FREERIDE. Devouring big terrain, the SB165 feels better the faster, steeper, and deeper riders go 1. SLACKER THAN MOST DH BIKES: The SB165 loves the steeps. 2. STEEP WHERE IT COUNTS: A steeper seat tube angle means pedaling back up isn’t a slog. 3. DUAL CROWN COMPATIBLE: Capable and already on Reed’s bike.

The Exie USA is a World-Cup capable cross-country race bike that flat out shreds. With a sub 2,000g frame weight and dw-link suspension, it offers a stunning combination of pedaling efficiency and downhill performance. We designed, built, and test­ed it in our Santa Cruz factory, which is pow­ered by the warm Cal­i­for­nia sunshine. RACE PROVEN Jen­ny Rissveds won the 2023 Lenz­er­hei­de XCC World Cup Cross Coun­try Event on the Ibis Exie, a bike we quite lit­er­al­ly made in our own back­yard here in North­ern California! BUILT BY US We build each Exie USA in our North­ern Cal­i­for­nia fac­to­ry. This gives us the utmost con­trol, which enables us to hit remark­able frame strength, stiff­ness, and weight tar­gets for this frame. SIZE SPECIFIC SEAT ANGLES Whether you're rac­ing short track or on a mul­ti day epic, the Exie's seat tube angles allows you to har­ness your strongest mus­cles, while reduc­ing any potential knee or wrist strain. We've also steep­ened the seat tube angles as the frames get larg­er, to allow rid­ers with dif­fer­ent inseams to achieve the same rid­ing positions. DW-LINK SUSPENSION Don't squan­der a sin­gle watt. Our dw-link sus­pen­sion plat­form offers incred­i­ble climb­ing effi­cien­cy and trac­tion along with plush, down­hill-crush­ing goodness. RIDE MORE, WRENCH LESS We use bush­ings where it makes sense and bear­ings where it doesn't. The IGUS bush­ings in our low­er link are lighter, stiffer, and vir­tu­al­ly main­te­nance free. We've also added fea­tures like a thread­ed bot­tom brack­et to help make any future main­te­nance easy. INTERNAL CABLE ROUTING Inter­nal cable rout­ing doesn't have to be a pain. We've added inter­nal tubes to our tubes, no pick­sets, flash­lights, or swear words required. 2.4" TIRE CLEARANCE You can run over­built, chunky tires; you can run light, big vol­ume fast tires, but whatever you run, you're not lim­it­ed by width. 2X BOTTLE CLEARANCE The Exie USA has clear­ance for two water bot­tles inside the front tri­an­gle on every size frame. INTEGRATED CHAIN GUIDE Drop the ham­mer, not your chain. LIFETIME WARRANTY If it's our fault, we'll fix it. Sim­ple as that.

The Arc is back. Conjuring up all the nostalgia, hoots, and hollers from yesteryear. It's your instant-feedback steed for any trail. Show it your singletrack, pump track, and your bikepack route too. It's got history to live up to and new history to make. And it's already impatient. FEATURES: SECURED FOR SPEED. While the ARC has roots back to the beginning of mountain biking, this frame is anything but a nostalgic blast from the past. If you run a chain guide, the ARC has integrated ISCG 05 tabs. SUMMIT PEAKS. MAKE SHAPES. A modern approach to hardtail geometry, without losing traction in the rear: riders have plenty of room to maneuver and respond to trail feedback without being too stretched out. Far beyond a juiced-up thorough-bred XC race bike, the ARC is built around a 130mm fork for a massively capable trail bike. DOWN COUNTRY, DONE DIFFERENT. Qualifying personal achievements with the phrase "for a hardtail" simply isn't necessary. The ARC absolutely rips when held wide open. THE SOUNDS OF SILENCE. Internally routed cable tubes with secure closures at entry and exit points make rattles a thing of the past. And an all-new chain slap protector virtually eliminates that chain-on-rubber sound, maintaining the serenity of the adventure. FEEL Spry, stiff, light, fast, fun as hell. DUAL SIDED DOWNTUBE MOUNTS. For going deeper. Riding longer. Carrying that thing you wish you brought on your last trip. FULL-STROKE DROPPERS ENCOURAGED. If a 200mm drop is your thing, you'll still have room to spare. PUT THE POWER DOWN. The downtube, seat tube, and chainstays flow into each other for a stiff and direct feel.
