$650.00
Wednesday is a frame with a decade of Surly's Omniterra design experience distilled into one steel package.

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.

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.
Ritchey Timberwolf Frameset
$1,199.95

$1,550.00

Cannondale Jekyll Carbon 2
$4,384.58 $5,999.99 27% Savings
Cannondale’s Jekyll 2 rolls on a fast, light, and tough BallisTec carbon frame that shrugs off enduro brutality and arrives at the bottom begging to do it again and again. And you will, too, with 165mm of Fox Float X Elite EVOL-guided travel in back and 170mm more up front, courtesy of Fox’s stiff, enduro-loving Float 36 fork. Together, they make easy work of gnarly descents where the only break you get is the climb back up. Since we’re talking about climbing, the Jekyll is no slouch in the uphill department, either, with a switch-on-the-fly rear suspension that offers Hustle Mode for tenacious efficiency. Put the power to the 12-speed SRAM X01 Eagle drivetrain via Descendant carbon crankset, and you’ll gain elevation as fast as you drop the competition. And, for all-mountain dominance, you won’t find better rubber than the Jekyll’s Maxxis Minions, wrapped around 29mm WTB Frequency Team rims that spin up fast and take enduro punishment like a masochist.

Surly Karate Monkey
$1,550.00
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
Surly Pugsley
$1,900.00
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.
Momentum iRide Rocker
$615.00
One look at the iRide Rocker's super-fat tires and you can't help but smile! Roll down rough city streets, through the park, on the beach, or even out through the snow. This light aluminum frame is built around massive 4-inch wide tires for a fun, cushy ride. The wide-range 7-speed Shimano drivetrain lets you spin up hilly terrain, while the powerful mechanical disc brakes give you excellent stopping power in all conditions. The comfortable saddle and handlebars put you in a heads-up, ride-for-hours position, while a built-in cup holder sets the laid-back tone for your ride.
Giant Reign SX
$4,080.00
Pick your line and charge it. The new Reign SX gives you added confidence on steep, hard-hammering descents. This amped up version of the Reign enduro and all-mountain machine is made for riders who gravitate toward steep, rough and aggressive descents. It offers a longer travel 170mm fork and robust components that make it suitable for unforgiving terrain. The super strong and stiff ALUXX SL aluminum frame features updated geometry with a longer cockpit that’s designed to optimize its 27.5 wheels. The trunnion-mount Maestro rear suspension system offers 160mm of smooth, active travel and is bolstered by the new Advanced Forged Composite upper rocker arm, which is lighter and stronger than the previous aluminum design. If hammering through rock gardens and flying down steep descents is your idea of the perfect ride, then Reign SX is the machine for you. - ALUXX SL-grade aluminum frame with 160mm of smooth Maestro suspension - RockShox Lyric RCT3 Solo Air 170mm-travel fork with Boost thru-axle - RockShox Super Deluxe Coil RT trunnion mount rear shock - Giant P-AM2 Disc wheelset with Maxxis tubeless tires - Shimano SLX 1x11-speed drivetrain with SRAM Guide RS hydraulic disc brakes

Cannondale Jekyll 4
$2,230.77 $3,199.99 30% Savings
When you’re on the Jekyll 4 from Cannondale, nothing dares get in your way. That’s because Jekyll’s tough aluminum frame shrugs off enduro brutality and arrives at the bottom begging to do it again and again. And you will, too, with 165mm of Fox DPS EVOL-guided travel in back and 170mm more up front, courtesy of Fox’s stiff, enduro-loving Float 36 fork. Together, they make easy work of gnarly descents where the only break you get is the climb back up. Since we’re talking about climbing, the Jekyll is no slouch in the uphill department, either, with a switch-on-the-fly rear suspension that offers Hustle Mode for tenacious efficiency. Put the power to the Shimano SLX drivetrain via Cannondale’s Si crankset, and you’ll gain elevation as fast as you drop the competition. And, for all-mountain dominance, you won’t find better rubber than the Jekyll’s Maxxis Minions, wrapped around 29mm WTB STP rims, well-known as workhorse hoops that’ll bail you out of your risky moves straight as an arrow. Shimano also provides powerful hydraulic brakes that keep you on course, even when that course can only be described as “sketchy.” So, jump on, slam the TransX dropper post, and flow this trail beast straight to victory.
Cannondale Trigger Carbon 1
$5,384.60 $7,749.99 31% Savings
Built for big days in the big mountains, the Trigger is pure, full-throttle descending mojo served up with a side of serious all-day pedalability. Its stiff, lightweight, full-carbon frame ensures dialed control on wicked descents, with suspension that you can flick into efficient Hustle Mode to devour climbs. Fox handles suspension needs with a Factory Float X EVOL shock cycling out 145mm of rear travel and a Factory Float 34 150mm-travel fork soaking up the big hits as you blast through rock gardens and launch drops. Rely on ravenous Maxxis Minion 3C EXO tires to bite hard into loose trails, while Cannondale’s flyweight HollowGram 30 wheels seem to disappear on climbs and hold up to dicey descents. SRAM gets you up the mountain fast with their extended-range, 12-speed Eagle X01/XX1 Eagle drivetrain and a Descendant carbon crankset, while their Guide RSC brakes bring everything to a controlled halt with incredible power and highly sought-after modulation. And, no trail bike is complete without the all-mountain performance edge offered by a RaceFace Turbine dropper post, routed internally with your other cables and hoses for an aesthetic as pure as the adrenaline coursing through your veins.
Cannondale Fat CAAD 1
$3,360.00
Looking for a fat bike without all the fat? Lightweight construction and nimble OutFront geometry make the Fat CAAD so agile and quick, you'll want to ride it all year long. The 100mm-travel Lefty Olaf fork is more than stiff enough to tell that big tire what to do, while the slack head angle and long front center lets you get rowdy on the steeps. The tight trail measurement keeps things crazy-nimble at slow speeds so you get the most out of that big, fat contact patch. Thanks to Cannondale's System Integrated cranks and offset chainrings, the FAT CAAD's Q-factor is up to 2.5cm narrower than the competition, so it feels like riding a bike, not a horse. The System Integrated crankset and offset Ai offset chainring also balance the short stays and allow for 2x compatibility with up to 4.8" tires!
Surly Big Fat Dummy
$3,025.00
The Big Fat Dummy is a long tail cargo bike that took a few too many doses of growth hormones. At first glance, you might say that Surly just put bigger tires on a Big Dummy. But if you said that, you'd actually be very wrong so just… don't. Think of Big Fat Dummy as more of a second or third cousin to Big Dummy rather than a brother. They share some of the same DNA and look sort of similar, but they're two very different bikes and really only interact when they both reach for the potato salad spoon at that family reunion that no one really wants to be at anyway. Now that that's out of the way, let's get down to the nitty gritty of what makes this hulking beast of a bike tick. Surly's goal with designing a cargo bike around fat tires was to create the most stable, stiff, and traction-laden ride possible while hauling a ton of stuff. Big Fat Dummy has a longer toptube and slacker headtube than its more svelt cousin giving it a nice, predictable, and stable ride. They also used thinner, lighter tubing to construct its cargo area so while it's an overall burlier bike, there's not much difference in weight. Big Fat Dummy accepts either 10mm or 12mm axles in the rear with a spacing of 190/197mm. That big ol' spacing equates to one thing: tire clearance for days. Big Fat Dummy maxes out at a massive 26 x 5.25" tire.* While that large of a tire provides the most traction and stability a bike can possibly offer, it's also a lot of rubber to push and might not be for everybody. Luckily, Big Fat Dummy is also a blast to ride with 3" tires too. It uses the same 100mm suspension-corrected fork as the Wednesday, meaning if you want to add a little squishy squishy to your ride, you can throw a Bluto on and let ‘er rip. If you intend to carry a passenger on your Big Fat Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility. All Big Fat Dummy framesets and bikes ship with a Dummy deck, rails, bags, and the aforementioned Dummy Rail Collars so you can immediately start hauling cargo — human or otherwise. Big Fat Dummy is ready and willing to carry all sorts of crap — literally. It's already in use on an organic farm in Ecuador so it's likely that it's hauled some form of manure by now. *Using a 26 x 5.25" tire will cause some drivetrain limitations.
