Northrock XC27 Mountain Bike Detailed Review

Powerful drivetrain, comfy saddle, aluminum constructions – those, my friend, are some of the features the Northrock Xc27 Mountain Bike promises.

If you are an outdoor enthusiast like me, you must recognize that nothing beats a good mountain bike. Having the physicality of conquering the most challenging terrains is just magical.

While most people look for an elegant design, excellent wheels, and good suspension in addition to the three features I mentioned, there is more to a good mountain bike.

A good mountain bike should also have steering accuracy, right pedaling height, and off-road strength. And the Northrock Xc27 and many other Northrock bikes embody all that.

Does it mean that it’s flawless? Of course not.

In this review, I’ll talk about the Northrock XC27’s main specs and features and who this bike is best suited for. So let’s get right to it!

Best Features of Northrock Xc27 Mountain Bike

Key Features

  • Hand-Built 17-Inch 6061 Aluminum Frame

The bike’s 6061 aluminum frame comes with several benefits that every mountain biker cherishes. For one, the structure is lightweight to give you an easier time moving the bike around.

Don’t worry about the aluminum frame breaking, as it is hand-built to guarantee utmost strength.

The 17-inch 6061 aluminum is also rust-proof. So, you don’t have to worry about it rusting following contact with water.

Furthermore, the aluminum frame is easy to clean to give you a neatly-looking mountain bike.

  • High-Grade Shimano Components

The key Shimano components are the triple crank and the drivetrain, which work cohesively to give you better performance.

The Shimano FCT4501 triple crank provides you with a broader gear range to help you find your best riding setting.

Additionally, the gear range boosts your cycling efficiency and overall performance. You get to climb almost seamlessly because of the Shimano triple crank gear range.

As for the Shimano Altus 21-speed drivetrain, it works seamlessly with the Shimano shifters to give you precision, better control, and quick shifting.

The drivetrain also makes it easy to add brake levers to offer you more bike control.

  • 5-Inch Fast-Rolling Wheels

These wheels by Northrock promises greater efficiency, better bike control, and agility. Given that they are massive, they roll over terrains almost seamlessly.

The wheels can conquer off-roads while maintaining steering accuracy. So, you can count on the bike to head where you want it to go, depending on how you steer it.

Also, the wheels promise quicker acceleration, given that they roll over surfaces stress-free.

Other Northrock XC27 Specs

  • Tektro Disc Brakes

You want your bike to stop when you press the brake. You generally have to control its stopping power, and that is what you get from Northrock Xc27.

Its Tektro disc brake gives you massive stopping power and control to ride safely off-road.

There are also integrated brake levers that are readily adjustable and promise to give you better bike control.

  • Well-Contoured Velo Saddle

The Northrock Mountain Bike comes with a well-contoured-Velo saddle that’s comfortable sitting on for long hours and riding on steep terrains.

So, regardless of the terrain, you can sit more comfortably and enjoy your ride outdoors.

Generally, you can count on the saddle for better performance outdoors. Plus, its design also improves the bike’s power output.

  • Double-Wall Rims

The rims are lightweight to go along with the lightweight aluminum frame, but they are also strong to serve you longer.

You can count on the rims to conquer the unpredictable off-road terrains.

  • Front Suspension

You don’t have to worry about the unpredictable rugged terrains as the bike’s front suspension will take care of everything.

It’ll absorb shock, vibrations, and massive impact when you ride on bumpy surfaces.

What’s more, the provision provides the rims with more excellent stability when cycling.

  • Threadless Stem

The stem, responsible for connecting the handlebar to the fork’s steer tube, is thread-less to give you an optimal cycling position.

So, it becomes easier to take on climbs without having to compromise your posture.

Besides, the presence of the 21-speed shifters makes climbs almost seamless. Therefore, it’s not all down to the thread-less stem.

The last thing you would want is a bike that puts your body in an awkward position. Luckily, you avoid that with the thread-less stem.

More Features

These features connect the bike hub with its rims and transfer the bike’s load between the two connecting points (rims and hub).

This bike’s spokes are strong to withstand enormous loads, something you expect from a premium-quality bike.
