Who is The Overdrive Meant For?

Just as the other high-performance hardtail mountain bikes in the market today, this bike is meant for the extreme riders out there. As you will learn in this DB Overdrive Sport 27.5 reviews, this bike has a very rigid frame, which allows the bike to endure the toughest of biking conditions and terrain for a long period.

The bike is quite affordable, bearing in mind that it is fitted with high-quality components and is fun to drive for both entry-level riders as well as the more experienced riders. Owing to the many benefits that this bike has to offer, it is rated one of the best selling hardtail mountain bikes today.

What Makes the DB Overdrive Sport a ‘Must Have’ Bike?

A Lightweight Frame

The 6061-T6 Aluminium frame has, to a certain extent, revolutionized the way other manufacturers view the designing and crafting of MTB frames. To begin with, the frame is very light; hence DB Overdrive Sport Weight should not be a concern for you. The lightweight of this bike enhances its performance and makes it easier to control and maneuver.

The 6061 combination of Aluminium, Magnesium, and silicon on this frame offers a comparatively high tensile strength. This is very important, bearing in mind that the bike is designed for extensive mountain biking.

Large Wheels and Tires

DB Overdrive Sport Wheels

Any experienced rider can attest to the fact that larger wheels are very beneficial when used on a mountain bike. As a matter of fact, you may have realized that a good number of hardtail mountain bikes within this range have either 27.5 inches or 29-inch tire. In order to offer optimal performance, the Diamondback Overdrive Sport 27.5 Mountain Bike comes with 27.5 inch Kenda Honey Badger 2.2″ tires.

These reduce the rolling resistance on this bike significantly thus making it easier to roll over obstacles. Again, the Kenda Honey Badger tires used on these wheels are of high quality and offer a good grip in all terrains.

Performance Drivetrain

DB Overdrive Sport 27.5 Bike Drivetrain

If you think of the Overdrive sport as just another 21-speed mountain bike, you are very wrong. The 27-speed drivetrain fitted on this hardtail mountain bike has a lot to offer an ordinary rider, as compared to its competitors. To begin with, the manufacturer does not compromise on the quality of components used on this mountain bike.

In this regard, the bike comes with Shimano front and rear derailleur, which are mated to a Shimano Altus M370 shifters. As such, you should expect a smooth and precise gearing experience with this bike. Additionally, the gearing system offers a wide range of gears for conquering steep ascents and descents with ease.

Powerful Hydraulic Brakes

Diamondback Overdrive Sport Specs - Braking System

Just as the price, frame, and wheel size are important considerations when shopping for the best mountain bike to buy, the braking system is something you must consider before making your final choice. Mountain bikes are built to be used on the challenging mountain trails and difficult terrains. Such an undertaking can be very dangerous for a rider and those close to him or her if the bike does not have an efficient braking system.

As a result, the Overdrive Sportbike by Diamondback is fitted with Tektro Auriga hydraulic disc brakes, a rather rare feature for bikes within this price range.Unlike mechanical disc brakes, hydraulic brakes are renowned for being very responsive and powerful. In addition to helping you avoid accidents, the powerful brakes on this bike improve handling of the bike in all terrains.

Great Customer Support

The Diamondback MTB manufacturer is renowned across the globe for unmatched craftsmanship and for producing quality products. To demonstrate that they are confident with their bikes, the manufacturer offers after sales service & customer support. This being the case, you can rest assured that you are buying a solid product that will give you any problem in the near future.

A Comfortable Ride

Although the Overdrive is a hardtail mountain bike, it is comparatively comfortable to ride, even in rough terrains. This may be attributed to the quality and effective front suspension frame. The suspension system is an important component of any mountain bike today.

This is because the bikes are meant for use in challenging terrains. To ensure that you have a comfortable ride, the Overdrive is fitted with an SR Suntour suspension fork to absorb all the bumps on your trail.
