For 2016, Diamondback gives its hardtail XC platform a bit of a facelift with the addition of snappy 27. 5in wheels for equal parts dexterity in terrain and hardpack speed. The 2016 Overdrive Pro Complete Mountain Bike sits at the top of Diamondback's Overdrive line of hardtails as a race ready whip bent on rocking the dirt. It boasts 120mm of plush RockShox cushioning up front, a Shimano 2 x 10 drivetrain, hydraulic disc brakes, and tubeless ready 27. 5 inch hoops wrapped in aggressive Kenda Honey Badger tires. The Overdrive Pro's frame is hand built from 6061 T6 aluminum alloy, often regarded as the best all around alloy from which to make bike frames. It's mostly aluminum, but also has composite components of magnesium and silicone that bestow the metal with rigidity, deformation resistance, and incredible torsional strength while still being one of the lightest alloys on the market. The bottom line is that this frame is ready to handle your worst while helping you ride your best. The geometry of the Overdrive Pro was perfected for tearing up the trail, with a moderate, 68 degree head tube angle and a 73 degree seat tube angle to provide an aggressive geometry geared towards efficient handling and hard power transfers. The handling is further enhanced by sub 17in chainstays, which take advantage of the mid sized wheels for able dexterity across enduro grade rock gardens. Diamondback pairs the Overdrive Pro with a RockShox Reba Solo Air fork boasting 120mm of plush travel to smooth out the trail and a lockout option for powering up climbs. The included 15mm thru axle also works to increase front end stiffness for enhanced steering and traction.
