Diamondback Sortie Comp Bike 2013

Diamondback and Fox Shocks Score with the Sortie Comp

The Diamondback Sortie Comp 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 Comp 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 near the bottom bracket keeps the center of gravity low and that helps the handling of the bike.

Diamondback’s Knuckle Box and the Fox Float CTD with rebound adjust and the new “Climb”, “Trail”, and “Descend” lever that gives you the ultimate control of your suspension whether you are climbing cross country style singletrack or descending a rutted and rocky trail.

Up front, the Diamondback Sortie Comp is built around a 140mm Fox Float CTD Air with an external rebound knob, 32mm Easton aluminum stanchions and magnesium lowers. The Diamondback Sortie Comp’s upgraded component choice over the Sortie ensures that the Sortie Comp continues to be a high performance machine. The Shimano Deore/XT drivetrain includes a Shimano FCM552 Dyna-Sys 10 speed crankset, Shimano Deore shifters and front derailleur. Stopping power comes from the Shimano M445 hydraulic disc brakes. An Easton EA50 stem and DB Lazer Series 31.8mm low rise bar comprise the cockpit while a WTB Vigo comp seat provides a style and comfort atop a Easton EA50 Double bolt clamp 31.6mm post for those all day spins. Last but not least Diamondback finished off the Sortie Comp 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.

Diamondback History

Since 1978, Diamondback has been at the forefront of innovative bicycle design. Diamondback produces bicycles suitable for every rider type. Whether you are an avid road cyclist looking for the newest, lightest frameset on the market, or crushing the downhill trails of Moab, or just looking to cruise the boardwalk, Diamondback has a bike to suit your needs. Diamondback believes that every bike they produce is a reflection of who they are. Therefore, each bike that rolls out of Diamondback’s factory embodies their core values which are precision, durability, and integrity.

    Comments about Diamondback Sortie Comp Bike 2013:

    Wow! This is a great bike. This is not my first mountain bike and I was a little worried at first but I couldnt say no to a FS bike with Fox shocks all around and a great component make up under $2500....I am not a light rider and I am pretty agressive and this bike takes all I can dish out. 5" of travel and one of the best rear suspension systems I have ever ridden (Knucklebox)equals a goat on the way up and a cheetah on the way down...LOL...but seriously the knucklbox eliminates almost all pedal bob and the climb setting hardly ever gets used on my rear shock. As most people will tell you the bike doesnt make the rider, but I have ridden bikes that cost triple this and I wouldnt think twice about purchasing another Diamondback in the future.
