Diamondback Mission 1.0 27.5" Bike 2016

Diamondback Mission 1 27.5 2016

Five minutes on the Diamondback Mission 1 27.5 and you'll be hooked. 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 1! The Fox Float 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 2016, 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 Mission 1 build, Diamondback chose to incorporate an array of sensible components that compliment and further enhance the impeccable design of the Mission 1 27.5. Suspension duties are handled beautifully by a plush pair from Fox Racing Shox. A Fox 34 Float Air fork with 160mm travel soaks up everything from small bumps to daring drops and rock gardens. FOX 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 Performance DPS Air keeps things tame in the rear, offering convenient remote lever access to the 3 travel positions and plenty of travel to absorb anything that comes your way.

The Mission 1's drivetrain is a practical blend of tested workhorse components, resulting in a pedaling platform that shreds as hard as you plan to push it. A 10 speed SRAM X7 Type 2.1 rear derailleur, SRAM X5 shifter, and SRAM 11-36t speed cassette form the sturdy core of the Mission 1's drivetrain. This simple, but efficient drivetrain cuts the fluff where necessary leaving only a reliable, hard-wearing drivetrain intact, so you can get to work exploring and spend less time all glassy eyed staring at your bike in the garage. A perfect blend of performance and practicality, the Mission 1's drivetrain is the steady heartbeat of the bike. A Race Face Ride crankset delivers all the power you need to climb efficiently and hammer through speedy sections of the trail. Paired with a 30t narrow-wide chainring, this responsive pedaling platform offers excellent chain retention and a wide range of gearing that will take you up and over all sorts of terrain. Shimano M447 hydraulic disc brakes offer all of the stopping power needed to handle daring terrain and modulate speed through tricky descents. The Mission 1 rolls confidently on a bombproof set of tubeless compatible alloy disc wheels paired with a set of the ever popular Schwalbe Hans Dampf 27.5 x 2.35" tires. Diamondback rounds out the cockpit of the Mission 1 with a full complement of DB branded components, ensuring that when you take a seat at mission control, everything is dialed!

Great Bike! Especially for the price.
First off, I'll start by saying that so far I've only used this bike for downhill, so my review can't be completely well rounded when it comes to the bikes climbing. However, that being said, this bike absolutely shreds downhill for an enduro bike. It's aggressive enough to ride all the rocks and drops you would want, and light and nimble enough to just send it on all the jumps. The bike is an extremely good jumper, feels very good in the air as well on take offs and landings. It won't quite handle the hardcore DH stuff as a full on downhill bike would, but it's tough enough to still not feel out of its place on any downhill course. The brakes work great, powerful and easily adjustable. No problems with them so far; maybe a 200mm rotor up front might help a little when the trail gets steep for long periods of time, but then again I rode this as a downhill bike. The suspension is really great, especially for a bike priced as this one. The Fox fork and shock are great at everything from small bumps to drops and hucks. Only thing I wish is that the Fox 34 would be upgraded to a 36 like the higher models, but that's really my only real complaint. Wheels are pretty good, don't know how heavy they are compared to others but the 650b size definitely helps with rock gardens and holes in the trail. All in all, this bike rocks, and for the price, might as well have left a tip.

I don't freaking even know
Arrived in good condition. Installation/setup instructions were terrible.
