Main Features Of Diamondback Bicycles Mission 1 Complete All Mountain Full Suspension Bike

Alloy Frame

You must agree with me that, the frame is the foundation of a mountain bike. If the frame is cheap in quality or made by cheap materials then I can assure you that you can’t take that bike for longer rides or the bike not last for long. So the frame materiel is so important thing that you have to check before buying mountain bike

In that case the DB mission 1 is not disappoint us. Its made by high-quality 6061-T6 aluminium frame which is able to withstand all mountain tracks smoothly with effective suspension system. Aluminum makes the bike frame super strong & light weight.

Suspension Mechanism

The suspension system that DB has implemented into the Mission 1 bike impressed us.

This bike has been created with a fantastic KnuckleBox suspension system. There is also a sturdy thru-axle built-in that ensures that suspension is provided with plenty of support to function to its full potential.

This unique suspension system is remarkably effective at dealing with bumpy terrain. Therefore, you can be sure to ride across rough terrain with complete smoothness. We found this feature improves the riding experience as it leaves you a lot less fatigued.

Quality Drivetrain

They have implemented Shimano parts when it comes to the gear mechanism too. The SRAM X7 drivetrain provides you with a total of 11 gears.

Therefore, you can be sure to ride across all kinds of hilly terrains and feel confident in knowing that you have the right gear selection to make the ride feel effortless.

Moreover, when it comes to shifting gears, you’ll notice that it’s incredibly smooth. As a result, you can be sure to shift through the gears quickly and with precision.

Having numerous gears to select from while riding in mountainous environments is crucial as the terrain is often changing on a constant basis. This bike allows you to keep up with it for a more enjoyable riding experience.

160mm Fork

How well does the fork keep up with the rest of the bike?

We were glad to find that this bike features with 160mm of travel suspension fork. This works in combination with the fantastic suspension system to diminish any of the bumps on surfaces.

The fork is of a very high standard and enhances the overall enjoyment of riding this bike.

Wide Hadlebar

Does the handlebar add or detract from the riding experience?

A lot of the time, the handlebar can be a tricky part of bikes to get right. This is largely because each person has their individual preferences as to how they’d prefer the handlebar to be.

Wide Handlebar - DB Bicycles Mission 1

In this case, the handlebar has a wide design and short stem.

We found this to be especially beneficial for people who are riding across challenging terrain and trails. This is because it provides you with an incredible amount of control for more precise cornering.

Moreover, they ensure that you are always given plenty of support while holding onto the handlebar. As a result, you don’t have to put so much effort into trying to keep a tight grip in fear of your hands being knocked off.

Dropper Seat-post

When it comes to mountain bikes, the design of the dropper post is an essential feature. It allows you to change the saddle height to the perfect position that feels comfortable for you.

This adjustable dropper post enables you to have the option to set different positions that are more suitable for different riding experiences.

Dropper Seatpost for DB Bicycles Mission 1

For example, people who are looking to do trail riding will find that setting the seat a little lower will put them in the best position for riding faster.

Whereas if you’re looking to ride for longer distances at a slower pace, you can set the seat slightly higher to keep your body upright. This is more comfortable for endurance-style riding.

Shifter & Brakes

The Mission 1 bike is comes with SRAM NX Shifter to change 11 speeds smoothly. Its a trigger shifter so you don’t have to be tricky to control your speed. Just use your finger to change the speed in no time.

As long as you have 11 speeds to change the speed, you also need effective brake to stop this bike. The Mission 1 bike equipped with SRAM Level T hydraulic disc brakes to stop the bike in a halt when you ride in downhill or wet surfaces.

So with this powerful braking system you can be relaxed about speed & brakes.
