Features Review of Diamondback Hook

Reliable Aluminum Hardtail Frame

DB Hook Hardtail Frame

Hardtail mountain bikes, including Diamondback Hook, have evolved over a long time. The primary changes are all in the frame.

For an entry-level bike, a durable, sturdy, reliable and light frame is all you can expect. This is what this bicycle delivers. All these contribute to the low-slung and slack geometry of the Diamondback Hook.

The bicycle comes with a 6061-T6 butted aluminum alloy frame with 1 1/8” headtube and a formed top and down tube.

The frame has integrated disc brake tabs that provide progressive geometry with an internal dropper ready. This is a perfect choice for excellent trail riding performance.

120mm Suspension Fork

DB Hook Front Suspension Fork

This hardtail mountain bike is undoubtedly the best choice for entry mountain riders.

However, it can also be taken for trail and park experience. Regardless of terrain, obstacles, bumps, and other rough trail features are bound to be encountered. This is why a suspension system is an excellent addition to such bikes.

This bicycle is a hardtail bicycle. It implies that it has a front suspension mechanism.

If you get this MTB, you’ll have the pleasure to use the SR Suntour XCM fork with 120mm of travel. The fork comes with 30mm stanchions, and coil spring with preload adjust. This tackles the trail obstacles and sucks up the rough stuff.

SRAM 8 Speed Drivetrain

Diamondback Bicycles Hook Drivetrain

Cruising the diverse trails requires that you have alternate gear options. Unlike the traditional bicycles which had only one option, the various gear choices enable you to maintain your riding speed regardless of the terrain. With the gear system, shifting from one gear to another should be smooth and as easy as possible.

The Diamondback bike drivetrain comprises a full ISCG-05 chain guide with roller front derailleur, SRAM X3 rear derailleur, SRAM X4 shifter, SRAM PG820 Cogset, and a KMC Z82 chain. All support 8-gear speed. They offer an easy and smooth shifting.

27.5 – inch Wheelset

Crossing the diverse trails requires that you have an overly effective wheelset. To reminisce, the wheelset comprises a wheel, rim, and spokes. All, working together, determine the roll-over speed and riding stability. A bicycle with narrow wheels provides less traction and stability. On the other hand, wide wheels offer great traction.

This hardtail comes with Diamondback SL-7 double-wall rims, Kenda Nevegal lite tires, and 14g stainless steel spokes. The set is 27.5”x 2.35” wide. This provides a great roll-over speed as well as better trail traction and stability.

Mechanical Disc Brakes

Diamondback Bicycles Hook Disc Brakes

When the ride is incredible, you tend to increase your riding speed slowly. Compounded by the smooth shifters, great suspension system and a wide choice of gears, you’ll find yourself cruising at an amazing speed.

This is where having a powerful braking system is required. Disc brakes are the mainstay braking system for modern bicycles.

To provide this maximum stopping power, the Diamondback Hook features the great Tektro Aires mechanical disc brakes with 160mm rotors both at the front and rear wheels.

They are supported by Tektro 2 finger allow linear brake levers with reach adjust. This combination brings the bike to a complete halt at your conscience.

Ready Ride Feature

You should always prioritize a bicycle that comes with a ReadyRide option. This is true unless you are willing to spend much time and energy assembling the bicycle after delivery. When it comes to ReadyRide bikes, they are delivered partially assembled. This relieves the great assembly work of the rider.

For instance, the Hook Bicycles is delivered 95% assembled. Note that the complete bicycle assembly requires an expert and up to 2 hours of time. To evade this, getting a ReadyRide option bike is prudent. When the Diamondback Hook is delivered, you only need to fix the front tire, handlebar, and the seat before setting off.
