Diamondback Mission Bikes Review

Jeff Balton

Diamondback Mission 1, 2 and Pro Together on Review

The Diamondback Mission is an all-mountain/Enduro bike that will comfortably take you on just about any mountain bike trail you can think of! With the Mission you can go on long, smooth rides without feeling as though you are working harder than you should be. The fun doesn’t stop there though! You can also go on rough, hard hitting trails with no concern as whether or not your bike will be up for it (it will be!)

The Diamondback Mission comes in three different versions, which you can find on this review:  

  • Mission 1, which is far above entry level but priced as if it is
  • Mission 2 which offers better components all around for the avid mountain biker.
  • Mission Pro which offers top level components and a ride that will keep even the most demanding of athletes happy.

What makes the Mission lineup so capable? Which model is right for you? Find out the answer to these questions and many more by reading this article!


The Bikes

The Diamondback Mission bikes will take you anywhere you want to go. How can they do this? It is all thanks to Diamondback’s well thought out bike geometry and specifications. Let’s start out by talking about the 27.5” wheels. This is becoming a pretty standard wheel size in the mountain bike industry and for good reason. 27.5” wheels (also known as 650b) are designed to bridge the gap between the older 26” wheel, and the large 29” wheel. 27.5” wheels offer an agile ride with a diameter large enough to easily roll over most terrain.

Next up on this Diamondback Mission review – its plentiful 160mm of travel on the front and rear. This amount of suspension will be enough to take you throughout a fun day in the bike park! However, it is not so much that it becomes a pain to pedal around like the 203mm downhill specific mountain bikes are. The suspension found on these bikes also have quite a bit of adjustment so they can be locked out (or close to it) for pedaling, and opened up for descending rough trails.


Diamondback MissionTo help you stop, all three of the Diamondback Mission bikes have been given 180mm rotors front and back that are paired with a set of hydraulic brakes. The large rotors mean heat can be dispersed easier, making brake fade something that you will not need to worry about with the Mission.

The last major thing that Diamondback chose to add to these jack of all trades is the 1×11 speed drivetrains. 1 gear upfront means no bulky front derailleur and a clean look. The 11 gears at the back are of a very wide range and provide riders with the ability to tackle pretty much anything without much trouble. The formula for a great bike is there, and the price is very reasonable. You should definitely give one of these bikes a try after reading this Diamondback Mission review.


Spec List

Here you will get a brief description of each Diamondback Mission model to help decide which is right for you. Remember that all of these bikes are excellent so do not feel like you are cheating yourself by choosing a more budget friendly option!

All of the models are built around the same 6061-T6 aluminum frame. The frame features a tapered head tube and the efficient Knuckle Box Technology suspension pivots.

Let’s go deeper to Mission review…


Diamondback Mission 1

Diamondback Mission 1 review

The Diamondback Mission 1 is designed for riders getting back into the mountain bike scene, or ones that are relatively new to the performance bike market. However, this model is also the least “full on” version of the Mission bikes. If you do not plan on riding intense Enduro style trails and runs, then I recommend this bike because it is more trail oriented. It is also the cheapest option and a steal of a deal considering the level of components that are on it.

Fork: The fork on the Diamondback Mission 1 is the Fox 34 performance fork. It is a simple to use air sprung fork that features compression and rebound adjustment. The FIT GRIP damper in this fork can be adjusted by hand to change how easily the fork compresses. This is a good trail fork but if you are into rough enduro and DH trails then you should look at the other Mission models.

Diamondback Mission 1 Fox suspension

Diamondback Mission has Fox 34 suspension w/ 160mm travel.

Shock: A Fox Float DPS is used for the rear shock on the Mission 1. This is an inline shock that features a three position lever (open, medium, firm), and rebound adjustment. Similar to the fork it is air sprung meaning the pressure can be adjusted for your weight. This is a good cross country or trail shock but not great for anything more intense.

If you do not plan on riding intense Enduro style trails and runs, then I recommend the Mission 1 because it is more trail oriented

Other Components

The rest of the components on this bike are what I like to refer to as budget friendly performance parts. They are quite good! However, they weigh a bit more than the parts on the Mission 2 and Pro models. The Mission 1 also doesn’t come with a dropper post or chain guide proving it is supposed to be used as a trail bike more than an all mountain machine. Some of the components on the Mission 1 include a SRAM NX derailleur and shifter, a Raceface Ride crank, SRAM level T hydraulic brakes, and a Diamondback cockpit.

Overall weight: Diamondback 1 weight is 31.8lbs

Diamondback Mission 2

Diamondback Mission 2The Diamondback Mission 2 is a pretty full on shred machine. Let’s see on Diamondback Mission 2 review, what does it offer?

It is more capable than the Mission 1 thanks to a few key upgrades. This bike is for people who want a very good ride but are not fully competitive in Enduro racing. It is also a good bike for people who are just starting to get into the Enduro racing scene as it provides a good starting point. You can also easily upgrade parts as you go if you feel that you need something improved.

The Mission 2 has KS LEV integrated dropper post!

Fork: The Mission 2 is outfitted with a Fox Performance 36 fork. This fork features all of the same benefits as the top of the line factory version. The only difference being it lacks the smooth gold Kashima coating on the stations, and the larger range of adjustment. The fork has excellent small bump compliance. It makes use of the FIT4 damper which can be put in open, medium, and firm modes. The air pressure can also be adjusted for each rider as can the rebound. The Fox Performance 36 fork will have you gliding over virtually any trail!


The shock on the Diamondback Mission 2 is where I find this bike lacks a little bit. It is the Fox Float DPS EVOL. There is nothing wrong with this shock. However, it is basically the same as the one on the Mission 1. The Mission 2’s Fox 36 fork out does this shock. Considering the price of the Mission 2, I am not surprised that they didn’t go with a bit better of an option. This is an upgrade point for those who want to race though.

Read the shock description under “Mission 1” to learn a bit about it the shock.

Other Components

Shimano takes care of the shifting and braking on this bike with their SLX lineup. The crank used is the trusty Raceface Aeffect which has a direct mount Raceface narrow wide ring attached. A big improvement over the Mission 1 is the Mission 2’s KS LEV integrated dropper post! This helps show that the Mission 2 is ready for climbing and descending. With the push of a button the post will be up for pedaling or down out of the way for aggressive standup riding.

The Mission 2 is for people who want a very good ride but are not fully competitive in Enduro racing.

As you can see from this review, Mission 2 is truly a well-priced mountain bike ready to introduce and make you fall in love with the Enduro style of riding.

Overall weight: Diamondback 2 weight is 31.9lbs (impressive considering the bigger fork and dropper post that the Mission 1 lacks)

Diamondback Mission Pro

Diamondback Mission Pro ReviewThe Diamondback Mission Pro is a race ready steed that will allow you to conquer any trail!

I seemed to have mentioned the word Enduro quite a bit throughout this article, but I would be wrong to not use it again here. The Mission Pro is a capable Enduro race bike that you can’t help but to love. This beast will feel at home when riding bike parks, sending big jumps, and pedaling across both rough and smooth ground. You can get some higher level components, but unless you want to spend thousands more on carbon, you will not need to. This bike also features a ton of adjustment. However, if all of that stuff is too technical for you, it may be better to go with one of the cheaper, more simple options.

Fork:  The fork used on the front of this bike is Fox’s top of the line Factory 36 Float. It features low speed compression, high speed compression, air, and rebound adjustment. Basically no matter how you want your fork to feel, you can get it with the Factory 36. It will comfortably take you on the roughest of trails with little worry. People will also take note of the gold Kashima coating on the stanchions.

Mission Pro’s Chain Guard


There was no expense spared on the Diamondback Mission Pro’s shock. The Fox Float X2 Factory provides all of the traction, and impact absorption a rider could ask for. It also features about as much adjustment as you can get. This adjustment includes high and low speed compression, high and low speed rebound, air, and a soft/firm lever for when pedaling or descending.

The Mission Pro is a capable Enduro race bike that you can’t help but to love.

Let’s move on with our Diamondback Mission Pro review.

Other Components: Shimano’s high level XT lineup ensures stiff cranks, smooth shifting, and powerful braking on this bike. Raceface looks after the cockpit as well as the wheels which make this bike coast like no tomorrow!  The dropper post on the Mission Pro is the proven Rockshox Reverb Stealth. Another bonus to the Mission Pro is the addition of a chain guide. The MRP guide ensures your chain will not fall off during any run. This is especially important for racers who are against the clock!  All in all, the Diamondback Mission Pro is incredibly spec’d and ready to tackle just about anything!

Weight: Diamondback Mission PRO weight is 33.2lbs (all of the extras and more adjustable parts add a bit of weight compared to the other Mission models).


Diamondback Mission Size Guide

You can see the size guide for different sizes on Diamondback.com

The Diamondback Mission bikes come in 4 different sizes. The small is good for riders from 5’4” to 5’7”. The medium is good for 5’7” to 5’10”. The large is good for 5’10” to 6’1”. Finally, the extra-large is good for riders from 6’1” to 6’4”. As a result of these offerings, most people should be able to get a Mission that fits them.


Diamondback bikes come partially assembled and are relatively easy to put together. This is especially true because Diamondback has instructional videos to help with the process every step of the way. Depending on where you order the bike from you can also purchase assembly such as from Amazon. If none of those options are for you, then take the bike to a local bike shop and they will happily put it together for a small fee.

Customer Reviews: It is mentioned many times that it feels like a real Enduro machine.

Customer Reviews

If you read customer reviews on the Diamondback Mission bikes you will almost only see good things. Larger riders compliment how indestructive the bikes are and the crazy amount of abuse that they can take. Other riders compliment the bike’s slack geometry and stability at fast speeds. It is mentioned many times that it feels like a real Enduro machine. You will be happy to see that even climbing is complemented (no doubt thanks to the Knuckle Box Tech).

The biggest complaint is that the lower end SRAM found on the Mission 1 is not as good as the Shimano found on the other models. However, this makes sense as the Mission 1 is more budget friendly. The SRAM parts are still nothing to laugh about.


The Diamondback Mission bikes will cater to riders looking to do just about any type of mountain biking. They pedal well, climb well, and descend well. For riders looking for a real Enduro style bike I would have to recommend the Mission 2 or Mission Pro. The Mission 1 is also good but seems to be intended for trails that are just a bit milder. Keep in mind that these bikes are not designed to be purely ridden on smooth trails.

If you never find yourself descending rough trails or spending time in a bike park, then you may be better off with a shorter travel mountain bike. All in all, if you are looking at getting into Enduro, or are already on the scene, you need to take a look at the Mission lineup!
