Diamondback and Rock Shox Score with the Sortie

The Diamondback Sortie trail bike eats up singletrack as well as it craves long descents making it an ideal trail bike for all day off road rides. Nimble enough for cross country rides, but with 5 inches of travel from the Rock Shox suspension front and rear, the Diamondback Sortie is stable enough to hit difficult terrain.

The 2013 Diamondback Sortie frame is built from 6061-T6 Weapons Grade Aluminum with a hooded hydroformed top tube, formed down tube, 9mmx135mm vertical drop out and Knuckle Box Technology. Diamondback’s Knuckle Box is the core of the single-pivot four-bar suspension platform. The pivot points were carefully placed to give optimal pedaling efficiency while still giving small and large bump compliance. Weight is always the enemy on a frame, but the weight of the Knuckle Box sits very low. This positioning of the weight low on the frame keeps the center of gravity low and that helps the handling of the bike.

Diamondback’s Knukle Box and the Rock Shox Monarch R keep the Sortie tracking straight, yet keeping the pedaling efficiency that a trail and cross country bike demands.

Up front, the Diamondback Scapegoat is built around a 120mm Rock Shox XC32 with Turnkey lockout, external rebound damping, preload adjust and a standard 9mm quick release axle. The Diamondback Sortie’s smart component choice ensures that you will have a capable machine that is still value oriented. The Shimano SLX rear9- speed derailleur is mixed with the Shimano Alivio front derailleur and Shimano Alivio Hollowtech crankset to form a 3x10 drive train that is capable over all different terrain. Shimano brings the stopping power with a set of M395 hydraulic disc brakes with the cockpit sourced from Diamondbacks very own DBL bars, stem and grips. Last but not least we’ve finished off the Sortie with a set of 32h SL-6 Doublewall Disc rims laced to alloy disc hubs and mounted with Kenda Slant 6 tires.

The Sortie is much more then just a cross country bike with more travel. Packaged smartly with Rock Shox suspension, Knuckle Box technology and bomb-proof wheels, this cross country / trail bike is ready for anything.

Innovative Technology
Diamondback full suspension mountain bikes are known for their Knuckle Box suspension design. The Knuckle Box, or Bell Crank, is Diamondback’s single- pivot four- bar suspension platform. The ideally placed pivots create a low leverage ratio which creates superior pedaling efficiency and small bump compliance. By placing the Knuckle Box low within the frame, the bulk of the weight is closer to the bottom bracket. This lowers the bike’s center of gravity which helps to improve tracking and cornering. The four bar suspension design further increases control over wheel- rate. Wheel rate is the effective spring rate when measured at the wheel. Diamondback worked closely with Fox Suspension to optimize the wheel rate to be linear to slightly progressive. This results in small bump compliance, more perceived travel, and bottom- out protection.
