Mountain Frames

If there’s one thing Tom knows, it’s dirt. When he first designed the Ultra he knew it would appeal to riders who demand specific ride characteristics and dirt slaying only he could deliver- and that was in the 1980s! Good design withstands the test of time, and the latest iteration of the Ultra is a prime example. Like its predecessor from 30 years prior, the new Ultra occupies a unique ride space from cross-country riders looking to get rowdy and go big to enduro riders lusting for some all-mountain shredding. Designed around a 120mm travel fork and super stable Boost 148 spacing, most of the fun is in the wheels. Designed to accommodate 29" or 27.5" wheels, the Ultra is highly versatile. Throw on some 29s for some trail-smashing XC riding, or saddle up some 27.5+ for some serious no-holds-barred shredding. The Ultra is a rough and rugged trail master that doesn’t know when to quit. - Compatible with 27.5 x 2.8 and 29 x 2.4 tires - Internal routing for a dropper post - Boost 148x12 rear spacing

The frame of the P-29er is built with Ritchey’s proprietary triple-butted Logic steel tubing. That combines with its modern XC geometry to deliver a breathtakingly balanced ride – beautifully mixing a snappy and responsive soul with a comfortable and predictable personality. The P-29er is the ultimate cross-country mountain bike. With its pedigree firmly rooted in the decades-deep lineage of its P-series predecessors that helped define the sport of mountain biking, this latest version of the P-29er is very much a modern machine with features demanded by today’s XC riders. It boasts BOOST spacing along with stealthy dropper post routing and an ultralight forged tapered headtube. It fits tires up to 2.3” and is built around a 100mm-travel fork. All of this comes together to enshrine the P-29er as a monument to the spirit of endless singletrack adventure.

STOMPING GAPS AND STAMPING PASSPORTS Load up the van, hit the road, climb a mountain, hammer it back down, huck the gap, throw the bike back in the van, drive to the bike park and do laps on laps. Hell, you could even rock up to the startline of the world's wildest races. The Nomad’s forte is being ready and willing to go wherever, whenever. The only thing it needs is a rider willing to press send. All the travel anyone needs in a single-crown bike intended for the steepest and deepest of trails. VPP™ suspension can be optimized to strike a balance between pedaling efficiency and all-out bump-chomping prowess. The Nomad is exceptional at absorbing the biggest hits so its rider can charge harder, with more confidence, in the very worst terrain. But because it's still pedal efficient, getting up to the best, highest trails isn't a chore like some other bikes. Sensitivity and constant traction On the Nomad, lowering the anti-squat reduced pedal kickback on big square-edge hits at speed, all while improving the overall sensitivity of the suspension to maintain traction at all speeds. Up and downhill. Flat-out bump control and tracking By reducing the starting leverage of the latest Nomad, we were able to improve body-weight influenced geometry stability throughout the travel. While reducing progression allowed the suspension to have consistently better tracking qualities throughout the stroke. Built to last Short, stout counter-rotating links connect the front and rear triangles to create an extremely robust chassis that reduces lateral flex. Simple expanding collet axles hold things together, pivots run on large diameter axles and bearings (which we offer free lifetime replacement for) and the lower link includes a grease-port for quick, easy maintenance. Frame stiffness tuned by size Bigger riders means bigger stresses on bigger frames. So we tailor stiffness for every size to make sure everyone gets the same ride quality. Details matter The details are completed by a neat mud flap to protect the rear shock plus tidy cable routing within the frame and swingarm, and rubberized DT protectors to shrug off strikes.

When you can only have one bike, and your mission is to ride that bike into oblivion then this is the one. From manicured bike parks to blown out loamy berms, alpine lines to backyard trails, the Bronson is as at home in the air as it is in the dirt. For the rider with a Peter Pan disposition or who wants to get into a pan flat tabletop position, the Bronson encourages bad behavior.

The 5010 is not just "the little bike" of our range. It makes even the most mundane trails feel like they're loaded with features to hop, skip and jump over. It's like having super-skills at your fingertips. The 5010 has always been more capable than many expected but with the traction-gaining 29-inch wheel up front and even more refined suspension the 5010 gives you a deft touch on the trails.

SEND-IT-ALL ON THE ALL NEW SENTINEL A bike that says yes to every trail, every ride and begs for more. The Sentinel rides the lines between planted bottomless sender and playful, poppy trail pony. This leaves it right in the sweet spot, as we like to call it. It's versatile attitude helps riders excel and push their limits, making it the one bike most will need. Its intuitive nature is easy to get acquainted with; you'll find yourself sending lines, jumps, and maneuvers you always felt were beyond your ability. Where before you went around, now you go over. Where you pushed up, now you pedal. Where you rolled, now you boost. It's time to Send-It-All. REFINING THE LEGEND The new Sentinel may have a similar silhouette, but we've fully redesigned the frame with updated industrial design, features, and geometry to turn it up a notch. The leverage curve supports the bike higher in its travel, leaving plenty of room for big hits while keeping it light on its feet to remain nimble and quick everywhere else. This gives it the lively, sporty attitude felt in the Spur and Smuggler without sacrificing its capabilities in rougher terrain. New size specific chainstays and a 64 degree headtube angle keep riders balanced with great traction on climbs and descents. All of this creates a bike that encourages new riders to push their limits, while ensuring a seasoned pro feels none. REFINED DETAILS We took a step back and looked for ways to improve the Sentinel, not just for the sake of change but for real, tangible steps forward that riders will feel and experience. We added internal frame storage in the downtube of our carbon frame. The B.O.O.M. Box (Burritos Or Other Munchies) is positioned below and isolated from the water-bottle cage mount. This allows you to leave your bottle installed in your cage while easily getting into the B.O.O.M. Box, reducing clutter and fuss on the trail. It also prevents noise by not placing any weight on the door itself. With an easy access lever and two supplied gear bags, riders can stow away snacks, tools, a tube, or anything else they want to have along for the ride. Wheel Size: X-Small: 27.5-inch Small - XX-Large: 29-inch

Big on wheels, short on fuss, this is the pinnacle of go-anywhere-anytime bikes. A balance of travel, wheel size and attitude makes this a true MTB for modern mountain biking. Whether that includes the rarefied air of the alpine or just local trailheads, built and burly trails or sublime natural singletrack, the Hightower is an all-terrain thriller.

The Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. It’s the bike you turn to when you’re not entirely sure what the night has in store. It’s the bike to grab when you want to have just much fun riding to the trail as you do from the trail itself. Singlespeeding is an integral part of Surly’s DNA, and the Lowside continues the tradition, by taking a simpler approach to trail riding. - 100% Surly 4130 Chromoly frame, main triangle is double-butted; 1-1/8" threadless Chromoly fork - Singlespeed “specific” (derailleur hanger but no Trip Guides) - Dropper post routing - Gnot-Boost rear spacing - Front and rear thru-axle - 26 x 3” or 27.5 x 2.8” tire clearance

Big on wheels, short on fuss, this is the pinnacle of go-anywhere-anytime bikes. A balance of travel, wheel size and attitude makes this a true ATB for modern mountain biking. Whether that includes the rarefied air of the alpine or just local trailheads, built and burly trails or sublime natural singletrack, the Hightower is an all-terrain thriller.

The Trust Tool for Any Trail Like the reliable tool you grab for every job, the Smuggler is the go-to bike for any trail pointed up, down, and all around. With dual 29 inch wheels, 130mm rear and 140mm front travel, the Smuggler may just be the most versatile bike in our lineup. A highly progressive leverage curve and comfortable, confidence-inspiring geo make it eager to keep going mile after mile while remaining surefooted in even the most technical terrain. Sitting squarely between the Spur and Sentinel in travel, geometry, and capability, it shares qualities of both. Inspiring and rewarding to hammer on your favorite singletrack, while never holding you back when the trail gets steep, the Smuggler will make sure you enjoy it all.

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

Ice Cream Truck solves the problem of having to choose between a fat bike and a trail bike. It boasts a symmetric 190mm-spaced Chromoly frame, suspension-corrected 150mm-spaced fork, and sporty trail-oriented geometry. Supported by massive 4.8" tires, itis ready to deftly tackle nearly any terrain. - 100% Surly Chromoly steel with 44mm headtube and internal dropper post cable routing - Frame is E.D. Coated for increased life expectancy - 1-1/8" straight steerer fork, Chromoly steel - 100mm threaded bottom bracket shell - Front and rear thru-axles, non-off-set - Universal cast dropouts accommodate thru-axle or quick-release standards

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

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-Country Bike Effortlessly explore, seek, and pursue the mountain in ways you never imagined. The Spur provides a sense of connection to the bike as if it were an extension to your body. Fast and efficient with an anti-gravity feel and laser-pointer precision that begs you to climb more, go farther, and descend anything you may encounter along the way. You'll instantly appreciate the free speed you're awarded while accelerating where you're usually accustomed to pedaling. Don't judge a book by its cover though, with all these lightweight and uphill oriented character traits the Spur requires no adjustment to descend like you're used to, you might actually go faster.

Wide open, dawn to dusk. The Highball is our race-bred XC hardtail. When the trail (or the competition) calls for the direct drive efficiency that only a hardtail can offer, the Highball is the choice. It looks straightforward but that belies the high-tech features and design hidden within. This is a modern take on the simple machine that many still choose to put battery acid in their thighs and fire in their lungs in order to conquer something. Whether you’re chasing medals, personal demons, or just some riding buddies, this is a hardtail you’ll be happy to log long hours upon. Hard on the throttle, soft on the body Hardtails are about as subtle as bikes come, and in the case of the Highball, simplistic refinement belies engineering effort. We’ve learned from our road biking pals that a great deal of a hardtail’s compliance comes from the seatpost: the smaller the diameter, the softer the feel, and with more seat post exposed to daylight, more compliance is had— which is the reason the Highball features low slung top tube and the smaller, 27.2mm diameter post. But you need not be sitting to recognize the ‘soft’ feel of the Highball— the dropped seat stays are made of custom laminate, finely tuned here in Santa Cruz for vertical compliance— and they’re oriented to isolate the top tube from high speed trail chatter, reducing feedback to the, uh, engine. SRAM Eagle Transmission - stronger, better shifting, wirelessly The next generation SRAM Eagle Transmission specced on our CC-carbon models is a radically robust, fully integrated and interdependent wireless transmission. Built around the universal constant of the wheel axle itself, the Full Mount hangerless attachment creates a far stronger connection to the frame and the super strong derailleur provides unprecedented strength. Shifting under load is made possible due to a combination of X-SYNC technology and cassette mapping, creating seamless shifts even during your hardest power output. The new AXS Pods are extremely ergonomic and highly customizable, so shifting gears is light and intuitive. It's simply the most advanced transmission and nearly as tough as the mountain itself.

The Spark RC SL is the perfect blend of top-notch carbon engineering, never before seen levels of integration and just the right amount of secret sauce. We wanted to make this platform faster than ever before both up and down the hill. Increasing travel, perfecting geometry, and applying input from the world's best athletes, we've created the cross country race bike of all cross country race bikes. If you think fast is fun, then you're going to love this ride.

THE PRIVATEER'S ULTIMATE ENDURO RACE BIKE Seriously. The Megatower’s big wheels, long-travel and tough carbon fiber chassis delivers the high-speed security traits of a race bike. Yet the relatively steep seat angle and size-specific geo maintain the Mega’s mega pedaling ability, elevating its reputation as the perfect choice for big gravity rides, park laps and enduro racing. Blind confidence on blind terrain VPP™ suspension can be optimized to strike a balance between pedaling efficiency and all-out bump-chomping prowess. The Megatower is exceptional at absorbing the biggest hits so its rider can charge harder, with more confidence, in the very worst terrain. But because it's still pedal efficient, getting up to the best, highest trails isn't a chore like some other bikes. Sensitivity and constant traction The Megatower's low leverage ratio to provide a more damped, controlled feel at speed. Lower anti-squat reduces pedal induced firmness and provides excellent square edge bump absorption, which gives you a greater margin for error when taking blind risks on wild trails. Thought out for privateer racers The Megatower's low leverage ratio to provide a more damped, controlled feel at speed. Lower anti-squat reduces pedal induced firmness and provides excellent square edge bump absorption, which gives you a greater margin for error when taking blind risks on wild trails.

The updated Rampage focuses Norco’s two decades of riding and building dirt jumpers into a platform where modern design, engineering, and jump-specific spec come together to push style and adrenaline to the next level. With help from our team rider Matt MacDuff, we’ve made some significant updates. Purpose-built for big air, this bike will literally up your game at the dirt jumps, pump track, or your local skatepark.

A Fair Advantage We tapped into everything we’ve learned from years of making the highest quality carbon full-suspension bikes and added the super-efficient Superlight™ suspension to make a World Cup-winning XC race bike. The Blur isn’t guaranteed to make you a race winner but being the lightest, full-suspension carbon XC bike we’ve ever made, it might be the difference between claiming first place...or just crossing the line. XC or TR The TR builds feature more travel (115mm rear, 120mm front) slightly beefier tires (Maxxis Rekon), a full height adjust dropper post, no lockout remote, and larger brake rotors. It's not a trail bike, it's a XC bike for certain courses. Light Carbon Frame The full-suspension Blur is lighter than most pre-race dinners you'll eat - 289g saving over previous generation. Reserve 28 XC wheels This is the lightest Reserve MTB rim (385g or 1367g complete). The rim bed is shallower and wider, meant for the newer generation of higher volume XC tires which are popular with elite racers. Geo to match The Blur's chainstay length is matched to frame size so every rider, no matter their height, gets the same balanced geometry and bike fit. Two water bottles Two water bottle mounts within the front triangle mean there's enough juice (or whatever electrolytes you choose) to keep the engine running. No proprietary gubbins There's no fiddly proprietary parts that could leave you stranded in a Cape Epic or Breck Epic campsite. Made to last many lifetimes The legendary Santa Cruz fit, finish and quality construction put this into a league of its own. The frame, bearings and optional Reserve wheels come with a lifetime warranty and any service is easy to do with our Rider Support pledge. Chainguide The only thing you'll be dropping is your competitors.

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
