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.

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 Shocks 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 Sortie 29er 1.0
The Diamondback Sortie 29er 1.0 demonstrates that you no longer need to sacrifice. If you haven’t made the leap to a 29” bike yet, now is the time. 29” wheels allow you to roll over obstacles more easily than 26” wheels. A larger wheel allows the rider to carry momentum through obstacles. Lastly, the larger diameter wheels are less prone to sinking in the sand and mud, due to lower ground pressure.

The Sortie 29er was inspired by the Sortie 26” platform. Diamondback wanted to retain the essence of the 26” platform with the added benefits of the 29” platform. Diamondback was successful; the 2013 Diamondback Sortie 29er is a lean mean trail- riding machine. The responsive nature of the suspension design allows you to spend half the day riding up the side of the mountain and the other half riding back down.

The Dimaondback Sortie 29 1.0 begins with 6061 T6 Weapons Grade Aluminum with hydroformed top tube, a butted and formed downtube, a seatstay bridge, tapered headtube, and 135mmx 9mm vertical drop out. Every aspect of the frame was built to be strong and durable without breaking the scale. The tapered headtube improves handling abilities and is stronger, which is essential for aggressive riders.

The Sortie 29er features Diamondback’s legendary Knuckle Box suspension design. Knuckle Box suspension is a single- pivot four- bar suspension platform. There are many benefits with this suspension design including better small bump compliance and improved tracking and cornering. The Sortie 29er series runs a 4.5" Fox Shocks Float CTD air shock with Boot Valve technology. CTD or Climb Trail Descend technology allows you to adjust your rear shock on the trail to adjust to the terrain for optimal performance no matter the terrain. The Boost Valve provides the feeling of endless travel, like a downhill bike. Flip the lever to propedal and enjoy Cross Country pedaling efficiency. Zip and zoom through single track without a care in the world. The nimble geometry allows you to clear tight corners, maneuver around ruts, roots, and sticks, without dropping a foot for balance. No matter what mountain bike trail you may find yourself on, the Sortie 29 1.0 will ensure you’re having fun.

To complete the package, Diamondback paired their Sortie 29er 1.0 frame with high quality components. To compliment the Knuckle Box suspension, Diamondback paired the Sortie 29er 1.0 with a Fox 32 Float CTD 29 RL fork. You’ll glide through the hills with 120mm of buttery smooth suspension. With CTD (Climb Trail Descend), you’ll be able to adjust the fork with the flip of a switch to accommodate the variable terrain. Shimano Deore 10 speed Rapidfire shifters paired with a Shimano SLX front derailleur and Shimano Deore 10 speed shadow rear derailleur will allow you to seamlessly shift through your gears. Shimano M445 hydraullic disc brakes will quickly bring you to a hault, in the event of a friendly gopher popping his head up on the trail. The WTB VIGO comp saddle provides a comfortable and stable riding experience, and will allow you to stay on the bike longer than before. With oodles of goodies, you’ll be amazed that the Diamondback Sortie 29er 1.0 does not break the bank.
