Feature Details of Diamondback Mission 2 Bicycle

Great Suspension

Diamondback Mission 2 Bicycle Rear Suspension

The Diamondback Mission 2 bike’s suspension is perhaps what wins many people. As mentioned prior, the bike comes with a famous KnuckleBox suspension supported by a beefy thru-axle. This not only keeps the bike solid but also flex-free through all the rough trails. The suspension handles the bumps.

The bike comes with a Float 36 Fork as well as Float EVOL LV rear shock which provides 160mm plush travel. You can imagine the experience of riding this bike through your best trails! Riding enthusiasts who have tried other all-mountain bicycles before attest that this bicycle can’t complete at its level.

Excellent Drivetrain

Mission 2 Mountain Bike - Drive train

The Diamondback Bicycles Mission 2  drivetrain is set similarly to the Diamondback Sync’r Pro’s model. Bearing in mind the components of a bike’s drivetrain, its Shimano 1×11 stays silent regardless of being pedaled or coasting. The drivetrain is free from chain-slap and an unusual pesky front derailleur.

The Shimano SLX M7000 11 gear shifting is smooth and light to touch. Starting from the chain to the rear derailleur, the Diamondback bike’s drivetrain supports an 11-speed functionality. This sees into that you achieve utmost speed as well as experience full mountain riding experience.

Wide Handlebar

Diamondback Mission 2 Specs - Wide Handlebar

Handlebars of mountain bikes often differ with handlebars of other bike categories. That said, whereas other bikes have a narrow and long stem handlebar, the DB Mission 2 bike comes with a short stem and wide bars. To be specific, they are the DB35 Alloy 780mm wide, 15mm rise and 35mm bar bore type.

This is perhaps an important feature when riding on technical trails. Bumps in paths can knock handlebars off your hands. Therefore, with such added leverage and wide bars, even small riders enjoy to the utmost. Mountainous trails often involve little plants. Therefore, maneuvering between trees will take some little practice.

Perfect Weight and Quality

If you are a fast rider and willing to take chances, you need to ascertain that you have a bike that allows so. Light and poor-quality bikes may not handle such abuse. That said, the Diamondback Bicycles Mission 2 being just under 32 pounds is no featherweight. With such a weight, you will be able to maintain a steady ride at any speed.

The bike also has a solid build. This means that the Diamond mission bike crashes as much as it rides. Some of the factors contributing to this build include the stiff Easton wheels, wise selection of solid components and its KnuckleBox suspension.

Dropper Post

Dropper posts is an important feature of any mountain bike. This feature allows you to alter the height of the bike’s saddle at your will. Dropping the saddle often comes in handy when you plan on getting quite aggressive. Being a mountain bike, such instances won’t miss out.

There are times you need to get comfy in preparation for the incoming terrain. In such instances, you need to adjust the saddle to suit your cycling requirements. That said, the Diamondback Mission 2 dropper post is the conventional KS LEV Integra Dropper. It also comes with a Southpaw Remote Lever.

Alloy Pedals

DB Mission 2 pedals

Pedals are perhaps among the main controlling aspects of a bike. Without the pedals, how would you ride? By pedaling, you provide the foot power required to steer the bicycle. It is therefore of essence that you get a bike with a high-quality pedaling feature. Without proper search, you will end up replacing them soonest. Some pedals are small and slippery hindering your overall riding experience.

Nonetheless, the DB Bicycles Mission 2 comes with the DB4L CNC platform pedals with sealed cartridge bearing and replaceable pins. Bike’s speed need to reflect the effort exerted by the pedals.

Easy Assembly

Bicycle assembly is often time-consuming and requires some basic technical know-how. This may be daunting to many people. So to say, it can take up to 2 more hours assembling the bicycle. Therefore, some riding amateurs go to the extent of hiring professionals to assemble them after delivery. This can be costlier.

The Diamondback Mission bike solves this by delivering the bike with 95% assembly done. Better known as the ReadyRide feature, it reduces significantly the overall time and skills needed for final assembly. You will have to complete the remaining aspects. This is however easy as Diamondback attach an owner’s manual and an assembly guide.
