Diamondback Mission 27.5" Pro Bike 2015

Diamondback Mission Pro 27.5 2015

Five minutes on the Diamondback Mission Pro 27.5 and you'll feel like nothing short of an elite rider. Packing 160mm of point-and-shoot full suspension travel, this 27.5” wheeled all-mountain bike wants to tear into rough, steep terrain, looking for hits and drops that would surely have the amateurs searching for a B-line. Crushing it downhill is one thing, but the aspiring enduro racer needs to be able to climb efficiently too. Not a problem for the Mission Pro! The Fox CTD equipped Knucklebox Migration suspension design reduces pedal induced motion without compromising small bump compliance, delivering you to the top efficiently and comfortably so you have more energy for another rip back down. The Mission takes advantage of the growing popularity of the 27.5" wheel size with this latest version, offering a ride that splits the difference of 29" and 26" wheels, giving you the best of both worlds. With 27.5", you retain the snappy handling of 26" wheels combined with the added obstacle clearance and acceleration typical of the 29er platform. Get on board, this ride is taking off and you don't want to be left behind!

For 2015, Diamondback is shaking up the suspension game with their newly improved Knucklebox platform. We are now in the era of KnuckleBox Migration. This means that Diamondback has refined the KnuckleBox platform to leverage even more performance from their already proven design. By migrating all the suspension components forward in the frame, travel is increased to 160mm and plenty of room is made for nimble, fast rolling 27.5” wheels. A newly designed, inverted KnuckleBox linkage and DB's proprietary single sided hardware round out this impressive new signature all-mountain, full suspension ride.

The KnuckleBox, or bell crank, is the core of Diamondback's single-pivot, four-bar suspension platform. Optimally placed pivots equate to a low leverage ratio, and ultimately to superior pedaling efficiency and small-bump compliance. This also allows the shock to work more efficiently and reduces pedal induced motion. It further reduces overall load on the system promoting improved shock and bearing life. Placing the KnuckleBox low within the frame lowers the bike’s center of gravity allowing it to track and corner better.

Wheel rate is the effective spring rate measured at the wheel, and it is a crucial aspect when considering suspension systems. A benefit of the KnuckleBox four-bar linkage is increased control over the wheel rate. Diamondback works closely with Fox, first obtaining the spring rate curves of their shocks so they can then optimize their wheel rates to be linear, to slightly progressive. The resulting ride yields superb small bump compliance, more perceived travel, and excellent bottom-out protection.

For the Pro level build, Diamondback chose to incorporate an array of high performance components that compliment and further enhance the impeccable design of the Mission 27.5. Suspension duties are handled beautifully by a plush pair from Fox Racing Shox. A Fox 34 Float CTD Adjust fork with 160mm travel and Kashima coating soaks up everything from small bumps to daring drops and rock gardens. CTD technology allows you to fine tune your fork's performance to match your terrain, giving you everything from plush rebound on aggressive sections to stability and minimal bob when climbing. The rear Fox Float X keeps things tame in the rear, offering the same convenient CTD adjustment and plenty of travel to absorb anything that comes your way.

The Mission Pro's drivetrain combines a handful of industry leading components, resulting in a pedaling platform that shreds as hard as you plan to push it. A SRAM X01 rear derailleur, shifter, and XO 11 speed cassette form the core of the Mission Pro's drivetrain. The X01 11 speed system is a proven winner that features excellent trickle-down technology from SRAM's premier XX1 system at a humbler price point. The perfect blend of performance and practicality, the Mission Pro's X01 drivetrain is the steady heartbeat of the bike. Race Face's Next SL crankset delivers all the power you need to climb efficiently and hammer through speedy sections of the trail. This ultra-lightweight carbon crankset provides a stiff, responsive pedaling platform paired with a 30t narrow-wide chainring, offering excellent chain retention and a wide range of gearing that will take you up and over all sorts of terrain. Shimano XT M785 hydraulic disc brakes offer all of the stopping power needed to handle daring terrain and modulate speed through tricky descents. The Mission Pro rolls confidently on a rock-solid set of Easton Haven tubeless ready wheels paired with a set of the venerable Schwalbe Hans Dampf 27.5 x 2.35" tires. The Mission Pro's cockpit is just as impressive, with a Race Face Atlas stem and handlebar providing a stiff yet responsive handling platform and a RockShox Reverb Stealth dropper seatpost that gives you capability to adjust seat post on-the-fly while riding, a must for enduro riding!

Independent Review:

For the rider looking for a bike that's designed with downhill performance as the top priority, the Mission is a solid contender. This is basically a modern freeride bike, although that term seems to have become less popular in recent years. Maybe "aggressive all-mountain" would be the more contemporary phrasing, but in any case, the Mission is most at home on steep, technical trails, and wouldn't be out of place taking laps in a bike park. At the same time, it's light enough that it can be pedaled to the top without the need for shuttle assistance, opening up even more possibilities for riders searching out the most difficult, remote trails they can find. - Mike Kazimer, Pink Bike
