2015 Surly Instigator 2 0

Some may remember a Surly model we discontinued called the Instigator. The Instigator was a burly hardtail made for going fast and going big. Our new Instigator picks up where that one left off. This thing is beefy and tough, yet quick-handling and well balanced. This new Instigator differs from the old one of course. Most notably, Instigator 2.0 is what we call 26+, designed to run 26˝ (559mm ETRTO) Rabbit Hole rims. At 50mm they’re quite a bit wider than standard MTB rims, and coupled with our 2.75˝ Dirt Wizard tires the overall diameter is about 27.5˝ (roughly 650b). All this means you get loads of traction and cushion yet you can still accelerate like mad. The toptube is long and the wheelbase relatively short, with a nice front/rear balance. This thing is made from the ground up to swoop, rail, hammer, drift, carve and fly. It goes downhill like nobody’s business and climbs well too. Instigator 2.0 employs a 44mm headtube, which paired with a tapered steerertube will provide a stiff front end and compatibility with lots of suspension forks. The rear end uses our new Modular Dropout System, allowing you to change up your drivetrain according to your riding preference. Frames ship with MDS dropouts in 10mm track end singlespeed, standard vertical with derailleur hanger and a 142 x 12mm thru-axle versions, while complete bikes ship with the direct-mount Shimano thru-axle chip. Pick your poison.

2015 Surly Krampus

Krampus is the evolution of the 29er. It’s not a fat bike. True, its got 3” tires on 50mm rims (we call this combination “29+”). But where fat bikes are really designed for slow-speed crawling, Krampus’s frame (geometry, tubing diameter/thickness) has been designed with a long toptube and as short a rear end as we could get away with given the wheel/tire size. This, when combined with the big, wide tires, results in a mad amount of rolling inertia and grip. It rips and responds well to body English. The big tires also offer a bit of suspension-like cushion. Krampus is a trail bike that also tackles all kinds of terrain. Krampus lives somewhere between bushwhacking, speed racing, and back lot dirt track riding, and all this makes it just plain fun to ride. Krampus’s hub spacing is standard 100mm front and 135mm rear, with rear-loading horizontal dropouts that accommodate a derailleur and single ring/cog drivetrains. It’s got clearance for disc rotors up to 185mm and is designed to run a high direct mount standard front derailleur. This type of derailleur will allow the most clearance at the tire. Even though there is no need for the sort of frame offset you find on our Pugsley and Moonlander models, chain and derailleur clearance at the tire remains a serious consideration. If you plan to use standard width rims and tires, you’ll be able to run a normal mountain triple crank. However, if you go with our 50mm Rabbit Hole rims and 3˝ Knard tires (and why wouldn’t you?) then plan to use a 1x or 2x crank…a triple simply won’t clear the tire. For best chain/tire clearance, we recommend either a Surly O.D. 2x crank or a 1x system. Other brands’ 2x cranks will work but may cause some chain-on-tire rub in the easiest gear combo. Got all that? O.K., then. Give it the juice and hang on.

2015 Surly Ogre

This is Ogre, Troll’s big wheeled brother sister. Troll and Ogre offer the same ability to accommodate a wide array of drivetrains, brakes, and cargo-hauling accessories. The main difference is that Ogre runs on 29˝ wheels, the Troll on 26˝. Built of 4130 CroMoly steel and based on the tried-and-true geometry of our venerable Karate Monkey, Ogre is designed to be a platform for exploration, commuting, trailer-pulling, on-road and off-road touring, and just riding along. Ogre features, mounts for linear-pull and disc brakes, three bottle cage mounts (the mounts on the top of the downtube allow higher or lower cage placement depending on your needs), ample room between the stays for high-volume rubber up to 2.5˝, and housing guides designed to accommodate three lines which cleanly organize full shift and brake housing. Ogre comes with our suspension-corrected (80mm) fork with threaded mounts for fenders and a rack. It will run cantilever or disc brakes so you can choose a system that best suits your stopping needs. Both fork and frame allow the use of a fender, disc brake, and rack at the same time. That’s surprisingly unusual in many modern frames. The fork also sports triple-boss bottle cage mounts, one set on each side. Each cage can be run in a high or low position, or you can run oversized Anything Cages. The frame is spaced for 135mm hubs, with the same rear-loading horizontal dropouts as our Troll. The dropouts feature a derailleur hanger, slotted disc brake mounts, M10 x 1mm threaded holes for mounting Surly Bill & Ted trailer-connecting hardware (or B.O.B. Nutz), and a dedicated anchoring point for a Rohloff OEM2 axle plate. We designed a ton of versatility into these dropouts so you can run a singlespeed, internally geared hub or full derailleur drivetrain, with disc or rim brakes, with or without racks and fenders, with new or older parts, whatever best serves you. Framesets and complete bikes are available in sizes small through XXL (equivalent to 24˝). The complete bike parts spec is durable and sensible…just the sort of value you expect from a Surly. If you’re like us, your bike needs will likely change by the day, week, month or year. Ride it to the office during the day, rip some local single-track after work, use it to tote crates of freakishly-large tubers next weekend, and tour that stretch of off-the-beaten-path double-track next month. With Ogre, you can do that.


An almost-fat bike, with a middle-child complex. Kind of a 29er, kind of a fat-bike the Krampus takes the good points of both. It has the flat traction the fat bikes rule, but with the speed and precision a 29er mountain bike offers its riders. It's like the best of both worlds without any compromise, as long as you like the colour green.
