The Sortie 29er was inspired by our beloved Sortie 26" platform. Our goal simple: retain ride characteristics of the Sortie trail platform while adding the benefits of a larger diameter wheel. Not a simple task by any means, but what we've come up with is a bike that's being hailed as one of the best 29 inch bikes on the market. We'll take that!
Diamondback's Design Philosophy is a no-nonsense approach to building quality bicycles. We want our bike designs to be straightforward: their hardware accessible and their suspension simple.
Diamondback's Sortie 29 3 brings affordability to a quality build. Our 6061-T6 Weapons Grade Aluminum frame features a hydroformed top tube, a butted and formed downtube, a seatstay bridge, tapered headtube, a 142×12mm E-Thru Axle drop out and Diamondbacks legendary Knuckle Box Suspension technology.
The Knuckle Box, or bell crank, is the core of our single-pivot four-bar suspension platform. Optimally placed pivots equate to a low leverage ratio, and ultimately to superior pedaling efficiency and small-bump compliance. This also allows the shock to work more efficiently and reduces pedal induced motion. It also reduces overall load on the system which will lead to improved shock and bearing life.
Placing the Knuckle Box low within the frame, situates the greatest weight of the bike closer to the bottom bracket, which lowers the bike's center of gravity and allows it to better track and corner.
Wheel-rate is also one of the most significant aspects of a suspension system. Wheel-rate is the effective spring-rate when measured at the wheel. A benefit of our four-bar linkage is increased control over the wheel-rate. Obtaining the spring-rate curves in shocks from Fox is necessary to allowing us to determine the wheel-rate. Working closely with Fox, we're able to optimize the wheel-rate to be linear-to-slightly progressive. This results in superb small-bump compliance, more perceived travel and excellent bottom-out protection. For our Sortie29 series, we're proud to run a 4.5" Fox Float CTD Air Shock with Adaptive Logic and Boost Valve Technologies. The "LV" 190×51mm air shock with rebound adjust and all new 3 position "adaptive logic" Propedal Platform keeps the rear riding plush without sacrifice on the pedal uphill. Fox's patented Boost Valve technology provides a feeling of endless travel like that of a downhill rig, but with XC pedaling efficiency. Climb, Trail, and Descend: this shock is ready for anything, instantly.
The Sortie 29 3 offers quality componentry in an economical package... starting with the Fox 32 Float CTD 29 RL 120mm travel air fork. This fork comes with an open bath cartridge, rebound, lever actuated lockout, alloy tapered 1.5 steerer, 32mm Easton aluminum stanchions, magnesium lowers, and a beefy QR15mm thru axle. The lockout function comes in handy for long sustained climbing. And at a hair under 4lbs, this little beast helps to keep weight down.
Complementing Fox's amazing suspension suite on the Sortie29 3, is a stellar Shimano package featuring a Shimano XT Dyna-Sys 10spd Crankset with an outboard bearing bottom bracket (24/38t). Shimano XT 10spd Rapidfire shifters, front derailleur and SGS Shadow Plus 10spd rear derailleur. We've also included a Shimano XT 10spd Cassette (11-36t), an HG74 10spd chain, 32h WTB Laser Disc Trail w/single eyelets Doublewall rims laced to sealed cartridge bearing hubs (15mm front/142×12 rear). A set of Shimano XT Hydraulic disc brakes with 180mm front / 160mm rear rotors provides ample stopping power. An Easton EA50 cockpit, seat post and WTB VIGO comp saddle provide a comfortable and stable riding experience.
Knuckle Box Frame Characteristics:
Tapered Head tube - Today's longer travel forks generate more stress on the head tube. Add in today's more aggressive rider and the need for additional strength in that region becomes imperative. Thus the 2012 Sortie 29er frame is equipped with a tapered head tube for enhanced steering and extra strength.
142×12 mm Thru Axle - Employing Shimano's new 142×12 mm E-Thru design makes for a stiffer and stronger rear-end on the bike.
Single-Sided Hardware - Single-sided oversized heat treated hardware is used for the three main pivot points allows for easy access to your 14 high-quality Enduro Max bearings simply with standard tools. No more removing the crankset to tighten or service your pivots.
Partnership w/ Fox - By providing suspension kinematics early in our design process, Fox is able to custom tune their shock to work precisely with our frames, improving performance.
Knucklebox Technology
LOW AND TIGHT - The Knuckle Box platform was designed specifically to be low and tight:
Low center of gravity: All suspension parts are positioned farther down on the frame for a stable and balanced ride.
Low leverage suspension design: Lower air pressure results in longer shock life, less frame loading and better pedaling.
Tight, compact linkage system of the Knuckle Box bell crank isolates and cradles the rear shock.
Tight and large anodized aluminum hardware, matched with Force-Rated Enduro Max Bearings: Withstands higher loads and better handles oscillating motion.
The Sortie 29 3 comes in 4 sizes: SM (15.5"), MD (17"), LG (19"), XL (21") and is grey/green.
If you are searching for the ideal full suspension 29er capable of sustained trail climbs or descents, super D's, Enduro's or all day in the saddle XC rides... you just found your bike my friend.
