One of the new 29er bikes to be released for 2012 is the Sortie from Diamondback. The 4.5” trail frame of the Sortie is a weapons-grade aluminum, which comes with a tapered head tube, knuckle box suspension platform, and 135x10mm vertical drop outs.
With impressive specs, the Sortie frame is a bruiser that tackles pretty much any terrain very well, especially because even with full XTR 3×10 and Easton EA70 wheels and cockpit, it weighs in at only 13.15kg.
Using Knucklebox suspension design, the 2012 Diamondback Sortie 29er Bike is built around 100mm in the rear and 120mm in the front. The design also offers 18” chain stays and uses a High Direct Mount front derailleur that makes the illusion of a loose seat angle though actually, it is around 72.5-73 degrees effective.
