Mountain Bikes

From dirt paths to singletrack, Talon keeps you rolling with smooth handling and confident control. This lightweight ALUXX aluminum frameset features classic off-road design made specifically for 27.5" wheels to strike just the right balance between control and quickness. The hardtail frame is optimized for a 100mm suspension fork, which helps soak up trail obstacles and improve control. For aspiring off-road riders looking to climb a little faster and get more comfortable riding singletrack, Talon is your ticket to XC adventures. - ALUXX-grade butted aluminum frame - SR Suntour XCT HLO 100mm-travel fork with hydraulic lockout - Giant double-wall rims with Maxxis Icon tires - Shimano 3x8-speed drivetrain with Tektro hydraulic disc brakes

Mountain biking has a learning curve, but you've got great head start in Cannondale's Catalyst 2. A strong, lightweight butted aluminum frame creates precise handling and a nimble ride that eats up singletrack and around town commutes equally well. 27.5-inch aluminum Alex rims roll quickly and smoothly atop Innova tires. The Shimano drivetrain provides 27 smooth-shifting speeds to conquer flats and hills, and Promax hydraulic disc brakes bring things to a stop right when you need them. On top of that, sturdy-yet-lightweight handlebars, stem, and saddle from Cannondale are sure to lessen the curve of learning.

Surly's Krampus rolls fast, holds speed, and devours corners. Surly built its Boosted frame and fork out of tapered and butted chromoly and gave the frame a long top tube and short chainstays, so it's playful, smooth, versatile, and durable. The 29 x 3-inch Dirt Wizard tires on 40mm Alex rims take your trail ride to new heights of fun. These big tires offer increased traction, incredible float, and reduce the need for suspension because the large volume is plenty to smooth the trail. You'll also get a SRAM NX 1x drivetrain, Answer Pro Taper bars, and SRAM Level hydraulic brakes to make you the new master of terrain that used to be out of bounds.

The Surly Pugsley may be the original fat bike, but this one is far from the original. Previously a great all-around fat bike, the Pugsley has been redesigned to be an ideal off-road touring and exploration rig. Surly lengthened the chainstays 12mm for stability when loaded and so your heels float effortlessly past panniers. The tweaked rear rack mounts on the dropouts let you center your rack over the wheel, despite the offset rear triangle. Those dropouts will take a 142x12mm thru axle if that's your schtick, but this rig comes with a 135mm QR hub, snug as a bug with a pair of adapter washers. Pugsley brings back the 135mm-spaced offset fork, so you can run a front wheel with a spare cog or freewheel as a bail-out option to swap with the rear if your internally-geared hub freezes up in neutral or you smash your derailleur having too much fun. A plethora of three-pack mounts give you gear-hauling options aplenty, and a Surly Moloko Bar gives your hands damn near as many options as well, so they stay clappably happy even on your longest, story-generating adventures.

Years ago the Karate Monkey helped start the 29-inch wheel movement and, as time's gone by, many companies ­– Surly included – have experimented with even more wheel sizes. With so many different types and sizes of tires now on the market, riders have begun to understand the effect that tire width has on overall wheel diameter, and with ample tire clearance, you can see the benefits of multiple wheel sizes all on one bike. 27+ tires have the same rolling diameter as a 29-inch wheel, yet you get all the traction and floatation benefits of extra-wide knobbies. And that's just the tires. The Karate Monkey frame has recently gotten a makeover that includes the addition of features like internal dropper post routing, a new tubeset that uses the same trumpet tubes found on Surly's Instigator 2.0, and a slight tweak in geometry that is more progressive and trail-oriented. The Karate Monkey uses a horizontal dropout with a derailleur hanger that features Gnot-Boost spacing, which gives the rider the ability to run any kind of mountain bike hub they choose. 10 x 135mm QR, 12 x 142, or 12 x 148 Boost will all work in the Karate Monkey frame. The frame uses a 44mm headtube for broad fork compatibility and is ED coated for an added layer of internal protection. If, at any point, you decide you want to throw on some skinny meats, standard 29-inch wheels and tires can be swapped in with no issue. If you want to round-house kick some trail right in the face, the Karate Monkey is your sled. - 100% Surly 4130 chromoly steel frame and fork; double-butted main triangle and 44mm headtube - Adjustable rear dropouts with 145mm Gnot-Boost spacing. Works with 142, 148 12mm thru, as well as 135mm w/ 10/12 washer - Internal dropper seatpost routing with 30.9mm seat tube ID - Clearance for 29 x 2.55 or 27.5 x 3 tires

Take to the trail with a new level of confidence. With its combination of grippy, rock-eating, plus-sized tires and smooth-riding suspension, the all-new Stance gives you more traction, more control and more fun. Built with a lightweight ALUXX aluminum frameset and our innovative FlexPoint rear suspension, Stance is the perfect way to improve your trail-riding game. Its new 27.5+ wheel and tire compatibility gives it a plush ride quality that soaks up bumps and adds more traction and stability. Combined with 120mm of smooth suspension travel front and rear, it’s a confident ride that will have you nailing new lines.

Raleigh's Talus 2 is all about fun on two wheels. Its steel frame is strong and ready to cruise, while the Suntour suspension fork and burly 27.5-inch wheels take care of every bump and pothole that dares get in your way. Plus, a Shimano 21-speed drivetrain, Shimano EZ-Fire shifters, and reliable linear-pull brakes make this bike easy to handle whether you're cruising down the road or cranking up a trail.

Built on an ALUXX SL aluminum frame, Fathom 29 features updated geometry that produces a stable ride quality for challenging XC trails. The frame is optimized for a 100mm suspension fork giving you efficiency on the climbs and total control on the descents.

With its progressive geometry, impressive construction and high-end features, the Cannondale Trail offers unreal performance and killer value. Built on a stiff, lightweight C2 alloy frame with 100mm of trail-absorbing suspension provided by the SR Suntour fork, the Trail 6 is ready for adventure. The 18-speed drivetrain, featuring a Shimano Acera Shadow rear derailleur and Altus shifters, provides smooth, fast gear changes, while the Shimano hydraulic disc brakes keep you in control no matter what the conditions. Trail-grabbing WTB tires and strong double-wall rims from Cannondale will have you flying fast and furiously, even when the trail does its best to slow you down. To optimize fit and handling, Cannondale uses 27.5-inch wheels on the X-Small and Small frames and 29-inch wheels on larger frame sizes. Dressed up with Cannondale's own high-quality aluminum components, the Trail 6 is ready for your next adventure.

Beginners and seasoned racers will love the lightweight, responsive trail-ready Cujo. With its huge 27.5+ tires, and dialed, stable geometry, the Cujo will make you more confident than ever on your favorite singletrack. The 120mm-travel Suntour fork shreds technical trail sections with ease. Find better grip than ever and float over obstacles with 3-inch Kenda tires, and tackle tough sections with 120mm of travel from the SR Suntour suspension fork. Durable Cannondale alloy handlebar, stem, and seatpost close out this tough, trail-ready package.

There is a first time for everything, including falling in love with mountain biking. Cannondale has crafted a bike you can trust in the Catalyst 1. A strong, lightweight butted aluminum frame creates precise handling and a nimble ride that eats up singletrack and in-town commutes equally well. The Shimano drivetrain provides 27 smooth-shifting speeds to conquer flats and hills, 27.5-inch Alex wheels zoom over all surfaces, and Promax hydraulic disc brakes bring things to a stop right when you need them. Sturdy-yet-lightweight handlebars, stem, and saddle from Cannondale give this bike the perfect learning curve for fun times and and falling in love.

The ECR is Surly's answer to those times when you just need to escape to the woods for a while to get away from the humdrum of life. Those familiar with this steel mule know it’s designed around plus tires, previously of the 29” variety. A fully loaded 29+ bike is an excellent way to explore and get away for a while… if you’re of a certain stature that is. For smaller riders, it poses several challenges though. And no one wants new problems when they’re in the woods trying to escape old ones. To solve this, Surly redesigned the smaller sizes of the ECR to work with 27.5+ while the larger sizes are still equipped with 29+. All you medium specimens out there get your pick of the litter as Surly is offering that size in both options. Other updates to the ECR include and are limited to: Gnot-Boost rear spacing and a killer new beige paint job. It retains the abundant accessory mounts that we all know and love like Surly Trip Guide for brakes and derailleurs, fender, rack, and Bill/Ted eyelets, and a Rohloff torque arm slot. The 29+ sizes have two water bottle mounts and one set of Three-Pack bosses. You’ve got lots of options to bring all your “necessities” with you and still have room for excess baggage if you’ve got it.

Venture into the world of mountain biking with help from Cannondale's women's Foray 1. A strong, lightweight butted aluminum frame creates precise handling and a nimble ride that eats up singletrack and bike lanes equally well, while lightweight Alex rims atop WTB BeeLine tires roll through trail obstacles. The Shimano drivetrain provides 27 smooth-shifting speeds to conquer flats and hills, and Promax hydraulic disc brakes bring things to a stop right when you need them. The sturdy-yet-lightweight handlebars, stem, and women's-specific saddle from Cannondale give you that push out to go explore.

The meandering trails of your dreams just got a whole lot closer thanks to Salsa's new iteration of the Deadwood. Wild bikepacking trips, epic point-to-point endurance bouts, and technical trail dominance — it's all yours with capable 29 x 2.6-inch tires paired to a short-travel Split Pivot suspension design that work together to keep you moving efficiently. Heat-treated 6066-T6 aluminum gives you a lightweight, stiff, and strong top-shelf platform, while the frame's endurance geometry ensures you'll stay in the saddle longer thanks to its comfortable riding posture. The Deadwood NX features SRAM's workhorse 1x11-speed NX drivetrain, SRAM Level hydraulic brakes, a RockShox Monarch RT3 Debonair rear shock, and a RockShox Recon RL 120mm fork to give you all-terrain prowess when you're out crushing the long trail.

The Timberjack Ti absolutely owns all paths — wooded, skinny, and flowy, making you the master of every ride thanks to its multi-talented character. The frame is constructed from custom, top-shelf titanium with a fast-handling geometry to deliver the stiffness needed to whip through tight turns and accelerate with instant power, while super-short chainstays make it easy to lift over obstacles so you can stay with the flow. Run it as a 27.5+ with up to 3-inch tires for maximum fun, or go for efficiency with a 29er wheelset — with Salsa's Alternator Dropouts you get an impressive grip of wheelset and drivetrain options to suit your style and intention.

What does ECR mean? Anything you want it to. Go camping, ride the Divide Trail, disappear into the woods, and conquer any road. Surly's ECR is a super capable camping machine/trail bike that's outfitted to explore wherever you point the front wheel. Surly's favored chromoly tubing damps road buzz and provides a nimble, responsive ride. The heart of the ECR is the 29+ wheel capability, with clearance for 29 x 3.0-inch tires. Fat tires mean smooth-rolling traction, stability to spare, and a touch of suspension over the roughest terrain. On top of all that, frame eyelets galore are just waiting for racks, fenders, and whatever else to make this your pedal-powered escape pod.

Say hello to Surly's rowdy, trail-shredding Instigator 2.0. The no-nonsense chromoly frame is made for charging hard and going big. It's super tough, yet handles nimbly and accelerates like mad. The heart of the bike is Surly's 26+ platform which has clearance for 50mm-wide rims and 2.75-inch tires, so you get endless traction and the rollover-action of a 27.5-inch wheel, coupled with the snappy, go-fast responsiveness of a 26-incher. The geometry is dialed for a 140mm travel suspension fork and features a long top tube and short rear end for more of the same fun. And this thing is versatile, the frame comes with dropouts for rolling singlespeed, or geared with a quick release or a 142x12mm through-axle with a Shimano direct-mount hanger.

Surly's Ice Cream Truck turns up the volume on fat. With unmatched traction and float courtesy of super wide tires (up to 4.8-inches wide!), and the flickable geometry of your favorite trail bike, this fatty feels frisky, limber, and ready for action. The symmetrically spaced 190mm rear end uses Surly's Modular Dropout system for an array of rear axles choices. 197mm thru-axle? 190mm geared? Singlespeed? All equally plausible possibilities with the Ice Cream Truck. A 44mm headtube provides fork options, and the frameset ships with a suspension-corrected, 150mm fork with a 15mm thru-axle. Surly's proprietary 4130 chromoly steel and corrosion-fighting ED coating add a hefty dose of tough to this bike. Now, where do you want to ride your Ice Cream Truck?

Wednesday is a frame with a decade of Surly's Omniterra design experience distilled into one steel package. Wednesday can ride over the same type of pretty much anything all of their other Omniterra bikes can, but they borrowed elements from both their Trail and Touring categories to create an Omniterra ride that can truly handle anything you want to attempt. Want to point the thing down a mountain and roll those dice? Wednesday has geometry spry enough to get you through the techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish when you have to ride back to the top. It also has the chops for any sort of expedition you may want to undertake. It has plenty of bottle mounts; triple bottle bosses on both fork legs and the down tube; standard bottle mounts on the seat tube and underside of the down tube; plus rack mounts on the frame and fork and fender eyelets on the dropouts, along with barrel bosses on the crown, fork legs and mid-blade, thru-blade eyelets on the fork as well. It also has internal dropper post routing and Surly Trip Guides to manage all the housing and cables on your frame with style. Wednesday also has its very own dropout design as well – a rear-facing, slotted dropout that can use either 10mm or 12mm axles and exit rearward or vertically. They’re cast steel and spaced at 170/177mm. Wednesday gives you a lot of options in the tire clearance category. In the full-forward, short chainstay position you can run 26 x 3.8? tires on 80mm rims and in the full-rearward, longer chainstay position you get the option of 26 x 4.6? tires on an 80mm rim. Wednesday is made out of Surly's own proprietary 4130 CroMoly steel and is ED coated for extra protection from the elements.

Years ago the Karate Monkey helped start the 29” wheel movement and, as time’s gone by, many companies ­– Surly included – have experimented with even more wheel sizes. With so many different types and sizes of tires now on the market, riders have begun to understand the effect that tire width has on overall wheel diameter, and with ample tire clearance, you can see the benefits of multiple wheel sizes all on one bike. 27+ tires have the same rolling diameter as a 29” wheel, yet you get all the traction and flotation benefits of extra-wide knobbies. And that’s just the tires.

The Karate Monkey uses a horizontal dropout with a derailleur hanger that features Gnot-Boost spacing, which gives the rider the ability to run any kind of mountain bike hub they choose. 10 x 135mm QR, 12 x 142, or 12 x 148 Boost will all work in the Karate Monkey frame. The frame uses a 44mm headtube for broad fork compatibility and is ED coated for an added layer of internal protection. If, at any point, you decide you want to throw on some skinny meats, standard 29” wheels and tires can be swapped in with no issue. If you want to round-house kick some trail right in the face, the Karate Monkey is your sled.

The Wednesday is the result of over a decade of Omniterra design experience distilled into one steel package. It can easily ride over or through most anything our other Omniterra bikes can and then some. With the Wednesday Frameset, Surly borrowed elements from some of their Trail and Touring models to create an Omniterra whip that can truly handle anything you want to attempt. Want to point it down the side of mountain? Go ahead, roll those dice. And if you make it to the bottom, you’ll be able to ride back to the top for round two. Wednesday’s geometry is spry enough to get you through techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish on terrain-crawling stuff. While Wednesday is plenty confident on terrifying terrain, it also has the chops for any sort of expedition you may want to undertake. Surly gave it all the necessary braze-ons and mounts for whatever accoutrements you feel necessary in your travels. Racks? Front and rear, friend. Fenders? You got it. Bottle mounts? How does triple bottle bosses on both fork legs and the down tube, and two sets of standard mounts on the main triangle grab you? They even gave Wednesday internal routing for a dropper post and Surly Trip Guides to keep everything nice and neat and free of rat’s nests. In the dropout department, Wednesday uses a cast steel, rear-facing, slotted dropout that can exit either rearward or vertically. They’re compatible with either 10mm or 12mm axles and are spaced at 170/177mm.

The Ice Cream Truck goes where most other bikes can’t. Snow, rocks, mud, sand — you name it, and chances are, someone has ridden it on an Ice Cream Truck. Don’t let that terrain-crawling ability fool you into thinking the Ice Cream Truck is slow and sluggish, though. A long top tube (best paired with a short stem) and short stays make it trail-approved and ready to rip. And with 4.8” tires on 100mm rims, “trail” is relative. Show a snowman who’s boss, ride through a sand castle — all while riding the perfect get-away vehicle. Or you can stick to riding terrain that won’t ruin a child’s day. It all starts with Surly's proprietary ED-coated 4130 CroMoly steel. ED coating provides a solid foundation for paint externally while adding a layer of corrosion protection internally. The Ice Cream Truck’s frame is symmetrically-spaced at 190mm and features Surly's MDS dropout system, so you have the option of running a 197mm thru-axle, 190mm geared or a single speed rear end. Each frameset comes with all three MDS chips so you can choose your own adventure. A 132mm wide PressFit 41 bottom bracket allowed Surly to play with the stays a bit more and move them a little further out, creating a much stiffer rear end. If you feel like swapping out the included suspension-corrected, straight blade fork, you’ll have plenty of options thanks to the Ice Cream Truck’s 44mm headtube. In a world full of uncertainties, there’s one thing you can count on: Ice Cream Truck will really take you places. At least when it comes to riding a bike — it can’t do much to help you fix the rest of your life.

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.

The Surly Pack Rat is designed around porteur-style racks and front-loading optimization, with a front cargo-specific design to eliminate steering issues. The fork features internal routing for generator hubs and rear frame dropouts to accommodate multiple drivetrain configurations. It’s an ideal choice for loaded commutes and bike trips with a lighter load, but also rides great when unloaded. - 100% Surly 4130 Chromoly frame, main triangle is double-butted; 1-1/8" threadless brazed Chromoly fork - Bosses front and rear for cantilever or linear-pull brakes, rack and fender eyelets at the dropouts, eyelets at the crown, and fully threaded through-blade fork eyelets for a front rack - Semi-horizontal dropouts with a derailleur hanger for geared or singlespeed drivetrains and/or wheelbase adjustability

The venerable Karate Monkey. When it comes to mountain riding, this bike brings everything you need to the experience and more. It's shod with 27.5 x 3.00 terrain-clawing Dirt Wizards for max traction on singletrack thanks to an aggressive tread pattern and cushy, wide footprint. But there's more to this agile trail runner's set of shoes — thanks to generous frame clearance, you can drop a set of 29-inch wheels in with up to a 2.50-inch tire if you desire something with less bite and similar roll-over capabilities. And, with Surly's Gnot Boost rear dropout spacing, you can comfortably run any kind of mountain bike hub: 10 x 135mm QR, 12 x 142mm, or 12 x 148mm Boost will all work in the Karate Monkey frame. Wheel choices aside, Surly built the updated Karate Monkey with a nod toward modern trail-bike geometry and includes internal dropper post routing, two or three bottle mounts (depending on size), threaded fender eyelets, and all the braze-ons you've come to expect from Surly for attaching racks, cages, and bags galore. Running gear consists of SRAMS's rock-solid NX 1x11 drivetrain with full-length external housing and Level hydraulic disc brakes for reliability when you need it most. Throw on a 140mm suspension fork and this all-rounder turns into a serious trail slayer. For what seems like a simple bike at first glance, the Karate Monkey offers much, much more. Listen to the Monkey and lose yourself in its ways.

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 as much fun riding to the trail as you do on 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: yes; Trip Guides: no) - Dropper post routing - Gnot-Boost rear spacing - Front and rear thru-axles - 26 x 3" or 27.5 x 2.8" tire clearance

The Surly Pugsley may be the original fat bike, but this one is far from the original. Previously a great all-around fat bike, the Pugsley has been redesigned to be an ideal off-road touring and exploration rig. Surly lengthened the chainstays 12mm for stability when loaded and so your heels float effortlessly past panniers. The tweaked rear rack mounts on the dropouts let you center your rack over the wheel, despite the offset rear triangle. Those dropouts will take a 142 x 12mm thru axle if that's your schtick, but can also be used with 135 x 10mmm QR hubs with Surly's Adapter Washers. Pugsley brings back the 135mm-spaced offset fork, so you can run a front wheel with a spare cog or freewheel as a bail-out option to swap with the rear if your internally-geared hub freezes up in neutral or you smash your derailleur having too much fun. A plethora of three-pack mounts give you gear-hauling options aplenty, so go wild with your build. - 100% Surly 4130 chromoly frame, main triangle is double-butted; 1-1/8" threadless brazed chromoly fork - Four sets of Three-Pack Mounts (two on the fork, two on the downtube), a water bottle mount on the seat tube, and front and rear rack mounts - 142 x 12mm rear dropout (or 135 x 10mm QR with Surly 10/12 Adapter Washers) with Rohloff torque arm slot - 135mm-spaced fork with 17.5mm offset for wheel swappability - 26 x 4.8" tire clearance in frame (with drivetrain restrictions), 26 x 4.3" tire clearance in fork
