The Key Features Of Northrock XC27 Mountain Bike.

Here are the standout features of the Northrock XC27 that work together to make it an exceptional mountain bike.

1. 17-Inch Hand-Built 6061 Aluminum Frame

6061 aluminum is strong and rigid, lightweight, and resistant to corrosion, making it excellent for a mountain bike because it allows it to handle rugged terrains effectively.

You can also move your bike from one place to another easily because it isn’t heavy.

Is Northrock XC27 worth it

Since it is rust-proof, you don’t have to be stressed out if your Northrock XC27 is exposed to water. Furthermore, it’s hand-built to ensure it is robust, and this frame is also effortless to clean, so your bike doesn’t have to be muddy, greasy, or dusty.

2. High-Grade Shimano Components

The crucial Shimano components in Northrock XC27 are the drivetrain and the triple crank, working cohesively to provide better performance.

This bike’s Shimano FCT4501 triple crank offers a broad gear range; hence you can explore different settings to find what works for you best.

In addition, the wide gear range also boosts your overall cycling performance and efficiency; thus, you can climb much easier.

The Shimano shifters and the 21-speed Shimano Altus drivetrain offer quick-shifting, better control, and precision.

You can also add brake levers more easily because of the drivetrain, providing you with more control of your Northrock XC27 mountain bike.

3. Tektro Disc Brakes

You want your bike to stop upon pressing the brakes, but that means controlling its stopping power. The Tektro disc brakes in this bike give you a huge stopping power and the control you need to ride off-road safely.

Northrock XC27 mountain bike also has readily adjustable integrated Shimano Altus EF-500 brake levers that help you manage the bike better.

4. 27.5-Inches Fast Rolling Wheels

These wheels offer better control of your bike, greater efficiency, agility, and since they are big, they roll over various terrains entirely without much struggle.

You can conquer different off-roads with these wheels and still maintain steering accuracy, so your Northrock XC27 will go where you steer it to go.

They also roll over surfaces quickly, allowing you to accelerate fast.

5. Front Suspension

Bike suspension helps you ride faster and more comfortably on off-road terrain, absorb vibrations, and offer additional steering control because of the enhanced traction. Therefore, you can cycle at higher speeds and for a longer time.

Northrock XC27 Strengths and Drawbacks

Northrock XC27’s front suspension will absorb the massive impacts, shock, and vibrations when you cycle on bumpy areas. Additionally, it gives the rims better stability as you ride.

Other Important Features:

1. Double Wall Rims

These rims are lightweight, strong, and durable, so expect to use them for a long time before thinking of replacing them. In addition, they will help you conquer unpredictable rugged terrains.

2. Threadless Stem

The stem connects the handlebar to the steer tube of the fork, and because it is threadless, you get an optimal riding position. As a result, you do not have to compromise your posture to climb.

However, the threadless stem is not the only component responsible for a nearly flawless climb, as the 21-speed shifters help make it possible.

3. Well-Contoured Velo Saddle

Northrock XC27 is made with a properly contoured Velo saddle that is comfortable to sit on even after many hours of riding. As a result, you will be comfy when riding regardless of the terrain, allowing you to enjoy the trail.

4. Stainless Steel Spokes

The spokes in this mountain bike are robust enough to withstand colossal loads, a quality expected from a top-quality bike. Hence, you shouldn’t worry about your Northrock XC27 spokes breaking as they do on most low-end bicycles.

5. Universal Mounts

You can effortlessly mount a bottle cage, child seat, and a rear bicycle rack on your Northrock XC27. These customizations will help you get the best from your bike.

6. KMC Chain

This bike’s chains are reliable, durable, and contribute to achieving a fast and light ride.
