The Vitus Nucleus 27 VRS Mountain is versatile enough to ride anywhere, with excellent capabilities for trail riding, going over rough terrain and overcoming obstacles on trails.
Below, we will analyze the riding experience, key features, components, and specifications as well as other versions of this bike.
Additionally, at the end of the review, we will also compare several best bike models. If you want to know more about bike reviews, don’t hesitate to follow us.
This bike has a nice geometry with carefully selected components.
It employs a large 29-inch wheelset and 140mm damped fork, giving me strong expectations for its off-road performance.
So I packed it and booked a hotel via IHG Hotels & Resorts.
Windrock Park (Tennessee) has everything from easy to difficult grades, from gravel roads to extremely rugged mountain terrain. It’s a great place to ride.
The most immediate riding feeling I got from the Vitus Nucleus 27 VRS Mountain while climbing was the quick and responsive power generation.
This was due to its hardtail aluminum frame that didn’t feel like a letdown when pedaling than a full-suspension mountain bike.
Then, on the steeper climbs, I was able to climb up without too much effort by using the largest gears available with the Shimano M5100 Deore, 170mm, 32t crankset and Sunrace 10 Speed, 11-46T Range flywheel.
Not only that, but the excellent geometry allowed me to maintain an upright riding position at all times, which kept the weight forward and pedaled more crisply on my upward climbing ride.
The Vitus Nucleus 27 VRS Mountain still gave me credit for its ability to descend as a hardtail trail bike.
First of all, the 120mm travel SR Suntour XCR32 Boost Air LOR DS fork could easily cope with this kind of rocky road, and the swift rebound and contraction reduced the jitter when riding, allowing me to control the bike easily.
On top of that, the aggressive geometry combined with the excellent grip provided by the Maxxis Ardent, 27.5″ x 2.25″ large grain outer tire, allowed me to get through the winding trails quickly.
Finally, the Clarks M2’s hydraulic brakes with the 180mm front and 160mm rear discs had reliable braking ability when I descended and gave me more peace of mind.
All in all, the Vitus Nucleus 27 VRS Mountain is a well-balanced hardtail trail bike with all-round performance. And the price really doesn’t let me find fault with it.
The Vitus Nucleus 27 VRS Mountain is available in a total of (S-XL) 4 sizes of aluminum frames for external cable routing.
This facilitates the maintenance and replacement of the cable ducts.
First, the looser geometry and 29-inch wheel diameter with a 2.6-inch outer tire give it a stable, high-speed descending performance.
The tried-and-true Nucleus geometry, coupled with the 27.5-inch wheelset, has good control as the trail winds its way through twists and turns, with reassuring stability and agility.
Next, the top tube and seat tube are reinforced to give the whole bike a stronger frame. This also provides the rider with the confidence to ride more intensely.
Finally, the mounting holes at the lower tube can support full-size kettle installation, which certainly brings more convenience.
The Vitus Nucleus 27 VRS Mountain is an all-round excellent hardtail trail bike, with the tried-and-true Nucleus geometry offering reassuring stability and agility, but for a more stable descent ride, the larger 29-inch wheelset would perform even better.
For this purpose we offer a hardtail trail bike with the same geometry aluminum frame under the same brand, but with a larger diameter wheelset for increased passability and stability.
Vitus Nucleus 29 VRS Mountain
The Vitus Nucleus 27 VRS Mountain and Vitus Nucleus 29 VRS Mountain share the same geometry and external cable routing on the frame, which facilitates daily maintenance.
Next, in terms of component selection, the Vitus Nucleus 29 VRS Mountain employs the SR Suntour XCR32 fork with 120mm of damping travel. The same Shimano drivetrain components and Clarks M2 brake components are used as on the Vitus Nucleus 27 VRS Mountain.
However, the biggest difference between the two bikes is that the Vitus Nucleus 29 VRS Mountain uses a larger wheelset, which is faster and smoother on the descent, and has better passing power.
So between these two nearly identical hardtail trail bikes, the Vitus Nucleus 27 VRS Mountain will operate more nimbly and the Vitus Nucleus 29 VRS Mountain will ride smoother and faster.
Below, we will list the specific parameters of the Vitus Nucleus 27 VRS Mountain in detail and some other brands of hardtail trail bikes at similar prices for your reference.

Vitus Nucleus 27 VRS Mountain vs Trek Marlin 6 Gen 2
Comparing the Vitus Nucleus 27 VRS Mountain with the Trek Marlin 6 Gen 2, I would recommend the former more because it comes with better components.
In terms of damping, the Nucleus 27 VRS Mountain uses the SR Suntour XCR32 Boost Air LOR DS fork with longer travel and better support as well as lubrication than the Marlin 6 Gen 2 Suntour XCT 30.
In terms of drivetrain components, both bikes use similar Shimano drivetrain components, giving them similar drivetrain efficiency and shifting feel.
Speaking of braking components, the Clarks M2 brakes on the front of the bike are stronger than the Tektro HD-M275 brakes on the back of the Marlin 6 Gen 2.
In the end, between these two hardtail trail bikes, the Vitus Nucleus 27 VRS Mountain will perform better and I would recommend it more.
Vitus Nucleus 27 VRS Mountain VS GT Aggressor Expert
The Vitus Nucleus 27 VRS Mountain and the GT Aggressor Expert are two hardtail trail bikes with their own specialties.
The first difference lies in their drivetrain components. The front bike uses a higher grade Shimano shifting system, and the 1×10 speed makes it more suitable for off-road riding than the latter’s Shimano Tourney 3×8 speed, but the latter will be faster on flat roads.
As for the fork, the Nucleus 27 VRS Mountain’s SR Suntour XCR32 Boost Air LOR DS fork has longer travel than the Aggressor ExpertSR’s Suntour XCM-DS, which has a better ability to cope with complex roads.
In terms of brakes, the former Clarks M2 brakes have faster brake response and better braking effort than the Tektro HD-M275 brakes on the rear Marlin 6 Gen 2.
So, between these two bikes, I would recommend the Vitus Nucleus 27 VRS Mountain, which has more advanced components and better handling of complex roads.
Vitus Nucleus 27 VRS Mountain vs Norco Storm 1 29
The Vitus Nucleus 27 VRS Mountain and Norco Storm 1 29 are both excellent and good hardtail trail bikes, both with their own merits.
In terms of damping, the former’s SR Suntour XCR32 Boost Air LOR DS fork has longer travel and lubrication than the latter’s Suntour XCM HLO.
When it comes to drivetrain components, both are Shimano Deore RD-M5100, but the latter has more speed.
As for the braking system, Nucleus 27 VRS Mountain’s Clarks M2 will have more braking power than Storm 1 29’s Tektro HD-M275.
However, the Norco Storm 1 29 has an elevated seat tube design that keeps the center of gravity stable between climbs and descents.
Finally, if you like the internal cable routing and dropper design then the Norco Storm 1 29 will be more suitable for you.
For a better ride when descending, the Vitus Nucleus 27 VRS Mountain is worth choosing.
Vitus Nucleus 27 VRS Mountain VS Orbea ALMA H30
The latter will have a higher grade in terms of components and will be correspondingly more expensive.
First of all, the Nucleus 27 VRS Mountain has longer damping travel, but the latter’s RockShox Judy damping has better initial sensitivity and performs better on continuous bumpy and rocky roads.
Then on the drivetrain components, the latter uses the higher grade Shimano Deore M6100, which is more efficient than the former, and the shifting feel will be more smooth.
As for the braking kits, both bikes enjoy excellent braking ability and both employ trustworthy brakes.
Overall, if you have enough budget then the Orbea ALMA H30 is really better; if you don’t want to spend too much money, the Vitus Nucleus 27 VRS Mountain is worth your money.
Above is my review of the Vitus Nucleus 27 VRS Mountain ride. In our opinion, this is a great bike for the money in its class at a similar price point and is suitable for every rider. That’s why we gave it a 4.8 rating.
