The Karate Monkey is Surly's 29" wheeled do-everything mountain bike. Why 29"? Because larger diameter wheels offer more traction and the have the ability to roll up and over obstacles better. The traction is enhanced by having a longer contact patch of rubber on the ground, which helps prevent your rear wheel from slipping on loose terrain and allows you to maintain your speed through corners. 29" wheels also have more air volume, so you can lower the air pressure more than you are accustomed to with an equivalent 26" tire. This enhances both the traction and rollover characteristics. Whether riding through babyhead rocks, braking bumps or tree roots, you’ll notice yourself getting through these sections much easier.

Sometimes simpler is better. Since 2003, Redline has brought this “simple” concept to off road riding with the MonoCog series of bikes. The durable full chromoly frame and straight legged fork are available in either 29” and 26” wheel models and three frame sizes. Easy to pedal single speed gearing and powerful Linear type brakes will start and stop you as you explore new trails.

• CRANK Redline Alloy 32T W Guard.
• WHEELS Alex DH 19 32H rims, Redline nutted quick release sealed bearing disc hubs, 14 gauge stainless spokes

The One 9 is the lightest production 29er single speed frame on the market. Made with the same custom drawn Easton GX2 Scandium as its geared brother, the One 9 delivers high performance through advanced tubing and tubing manipulation. From the outset, the One 9 had seemingly simple design objective: create the best-riding single speed possible. This meant that we wanted a blazing fast frame, with no discernible flex at the bottom bracket or through to the rear wheel without creating an overly harsh ride. Niner went to Easton, and worked directly with them on the tube set to meet these goals, creating a frame that did exactly what we were after: a fast, nimble, but comfortable ride.

The S.I.R. 9 is the most versatile bike in the Niner stable, fusing the “steel is real” feel of Reynolds tubing with the ability to run the frame as either a geared bike or single speed. The S.I.R. 9 uses the same custom drawn Reynolds 853 tubing as the M.C.R. 9 and combines it with Niner’s ultra-light eccentric bottom bracket. Custom “breezer” style forged dropouts have a replaceable alloy derailleur hanger and come with an insert piece for running the bike as a single speed to eliminate the unnecessary derailleur hanger for a clean look.

Niner’s own EBB, at 100 grams, is the lightest eccentric bottom bracket on the market. In addition to being light, it’s extremely functional. The EBB has more swing than any other EBB, over a full link, so you will never have to hunt down a half link to get correct chain tension and vertical dropouts mean you’ll never have to futz with the disc brake to remove the wheel.

• Custom blend of 4130 cromoly steel frame tubes with eccentric bottom bracket
• Cromoly steel rigid fork; suspension corrected
• Truvativ Stylo 1.1 singlespeed crankset
• Avid BB5 mechanical disc brakes with Avid FR5 levers

“Mono-Cog Deluxe” is really what you get with the high quality double butted Sanko tubing in the frame and fork of the Monocog flight. The frame uses slider style rear dropouts for easy chain tension adjustment, and the right dropout can be changed to fit a derailleur. Powerful Avid disc brakes, WTB pure V saddle, and upgraded wheels all fit together to give you a great ride.
