Mountain Frames

The cult favorite continues. The Honzo ST frame is the bike you'll find under a messenger, under that old-school soul ripper, or under the rider who really wants to build something beautiful and custom. A 66-degree headtube is ideal for all kinds of tricky, steep terrain, and the short seat tube allows for longer dropper posts. As always, the Honzo ST frame features adjustable dropouts so you can run your favorite drivetrain without any issues. FEATURES KONA CROMOLY: Very few materials offer as much shock absorption, durability, and supple-ride characteristics as steel. We've never strayed from cycling's original material and have worked tirelessly to adapt, refine and innovate Kona Cromoly framesets as rider demands continue to evolve. INTERNAL HEADSET: Bearing cups are actually pressed into the frame and are easily removable. An internal headset also reduces stack height, so the height of the stem and bars are more adjustable, giving the rider the best fit possible. TAPERED HEAD TUBE: More girth at the bottom of the head tube better distributes shock force, prolonging the bearing life of the headset itself and eliminating brake shudder, while providing confident steering performance. The inherent strength of its triangular design also means a stronger steering position and improved balance, giving the rider more control in rough terrain. A zero-stack, tapered head tube also puts strength where the load is going—into the lower headset cup—maximizing bearing durability where it's needed. TUBELESS COMPATIBLE RIMS: Tubeless rims allow for tires with more puncture resistance; the ability to run lower tire pressure, which provides better tire grip on the trail; lower rolling resistance; and weight savings over traditional tube and tire systems. 12x148mm AXLE: 12x142mm, 12x148 and 12x157 rear axle standards provide two major advantages to the Kona rider: the 12mm diameter of the rear axle provides the rear hub and frame with a stiff interface, while the 142/148/157mm outer diameter of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted.

When you think of the perfect mountain bike, what comes to mind? For us, it's the all new Spark 900 Tuned. Why, you ask?

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.

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

The Ogre can get you to your job during the week, then way out of town on the weekend. It’s not sluggish on pavement or gravel and can also hold its own on singletrack. Ogre brings several sensible features to the 29er platform, including horizontal slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefy tire clearance. - 100% Surly Chromoly steel, double-butted main triangle - TIG-welded, Horizontal slotted with derailleur hanger, Gnot-Boost spacing allows the use of 135mm QR hub, 142 x 12mm thru-axle or 148 x 12mm Boost hubs.

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
