Built to shred.

The Diamondback Mission 27.5 Pro Complete Mountain Bike is built to take on the hairiest trails around, without so much as flinching. Building on the Mission’s history of smoothing out gnarly terrain, it adds bigger wheels and more aggressive geometry to the formula, making it even more potent. And with FOX suspension and a SRAM X01 drivetrain, there’s not much, if anything, that this beast won’t handle with ease.


Like the previous Mission, the latest version’s aluminum frame is built to withstand aggressive riders getting wild in hairy terrain. It runs an updated version of Diamondback’s Knuckle Box suspension platform, which has been redesigned to provide more support in the mid-stroke, allowing you to push the new Mission harder, especially in corners. The geometry has also become more aggressive. The head angle has been relaxed by half a degree to 66.5, and, when combined with the larger wheels, it provides significantly more stability, especially when initiating corners at speed. The seat angle has been steepened by a degree to 73, keeping you in a more aggressive position for technical climbing. And although the wheel size has grown, the chainstays have been lengthened by a modest 10mm, keeping the Mission responsive, while preserving the stability you need to ride fast.


For the Pro build, FOX handles the suspension duties, with a FLOAT X CTD rear shock, and a Factory Series FLOAT 34 CTD up front, with a full 160mm of travel. It runs SRAM’s X01 one-by-eleven drivetrain, which yields a front-derailleur-free setup, while providing complete chain retention and the gear range of a traditional double chainring drivetrain. The exception is the spectacularly light, incredibly strong Race Face Next SL carbon fiber (30T) crankset. Stopping is handled by Shimano’s proven XT brakes, with IceTech rotors. The cockpit consists of a Race Face bar and stem, a RockShox Reverb Stealth seatpost, and a ti-railed Diamondback saddle. It rolls on Easton Haven wheels, wrapped in Schwalbe Hans Dampf tires.


The Diamondback Mission 27.5 Pro Complete Mountain Bike is available in four sizes, from Small to X-Large, and in the color Red.
