Some say the SB140 never met a dirt it didn't like. We agree in spades. What's your pleasure? Drag a bar. Make an edit. Stay out after dark. Try it. Land it. Or just stay at it. Happy to pedal. Greedy for more. The mayor of jibtown, proudly wearing the rip crown. The SB140. Down to fun.

Forget the numbers. Mute the speculation. Let the other guys invent cute alternatives for "cross country." Steer clear of pigeon holes and limiting beliefs. Strap on your blinders and go get lost. Then decide what the SB120 means to you. And you alone. Definition ready.

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.

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.

The rebel yell of the middle child. Fed a steady diet of super-tech climbs. The SB130 was built to crush the biggest terrain. No trail "too" anything. Point it up or down. Enter a last-minute enduro just for the eff of it. We say no one bike can rule all. But the SB130? One bike that rules.

"Race bred". It's not just a slogan printed on the SB150 top tube. We've been pinning on numbers and pinning the throttle since 1985.

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. 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 side. - 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 aluminum bottom bracket shell with integrated ISCG-05 tabs. This critical drivetrain interface is now more durable, cleaner, and easier to service. - 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.

Then decide what the SB120 means to you. And you alone. Definition ready. With a new-gen approach to our shortest travel bike, the SB120 now has a frame silhouette that’s inspired by its longer legged siblings. Torsional precision and impact clearance has increased, without transferring unwanted feedback to the rider. And the refined Switch Infinity makes this bike punch well above its weight. 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 lightweight and durability. 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. A relatively linear progression curve gives riders usable, active travel at 30% sag – a far greater margin than other 120mm travel bikes. The SB120’s small bump compliance delivers incredible traction. Its supportive mid-stroke ensures riders don’t blow through travel when pushing against the suspension in turns or when getting the wheels off the ground. Oh shit moments are handled with ease – the curve has been tuned with increased bottom-out control. - Internally routed cable tubes with secure closures at entry and exit points eliminate rattles and cable rub.

A decade ago we peaced out of the lycra game. While we were busy getting down, XC got a lot more X, calling for the comeback of a legend. The ASR helps today’s racers be faster where they have to be. On first blush it may appear to have peers, but don’t get it twisted. The reincarnated ASR is a lot like nothing else. The ASR is back. We’ve never made a lighter full-suspension bike, but that’s just half the story. It brings proper suspension to proper mountain bike racing. The kind that takes skill, not just lungs. The new ASR marks the most extensive carbon project we’ve ever tackled. Yielding the lightest full suspension bike in our history, contemporizing our flex stay design to check today’s kinematics standards, providing proper sag, killer small-bump sensitivity, insane traction and 100% usable travel. Custom ply shapes, critical material choice, intelligent draping methods, and smooth transitions between every carbon ply have eliminated redundant carbon, giving radical strength for super lightweight. Such a boundary pushing schedule driven from in-depth carbon analysis tools marks a Yeti first. We wanted to kill carbon redundancy everywhere, not just where it was easy. Our 20+ years of carbon-only experience told us we could remove solid volume at pivots and still exceed the demands of XC, with no downside on performance or bearing life. Another goal for the ASR was to engineer each frame for the same ride characteristics to give every rider the same feel, regardless of size. Since theASR uses single-ply carbon layups to eliminate redundant carbon, each sheet had to be precision cut. Tedious? Yes. Worth it? Absolutely. Doing so allowed for size-specific tuning at a much more sensitive level, and accurately matching torsional stiffness and chassis-flex profiles too. The year was 2003 – our flex stay design was a decade’s ahead approach to XC full suspension. Today, the incarnated ASR considers the relationships between leverage rate, link size, material properties of the carbon layup and modern short stroke shocks to deliver responsive, efficient, and astonishingly light XC-specific suspension. - Secure closures at frame entry and exit eliminate rattles and rub. External brake routing from bar to head tube for ease of travel, plus there’s no aero advantage to hiding them anyway. - On the muddiest race days, the integrated rear fender keeps debris from impeding suspension movement. Weighing next to nothing. It’s a frame feature you’ll only notice how big of a difference it makes if it’s gone. - Hangerless Interface creates the strongest and most precise shifting by allowing Eagle Transmission derailleurs to mount directly to the wheel axle and grip both sides of the frame. But Hangerless Interface is also perfect for legacy drivetrains, thanks to the included Universal Derailleur Hanger (UDH).

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

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

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
