The Vitus Nucleus is the 4x winner of the MBR magazine £500 Hardtail of the Year award. This model rolls upon 27.5″ wheels and is equipped with superb components aboard a quality frame, giving you more confidence and performance than you would expect from a bike at this price-point. Plus, it features SR Suntour suspension and a Box Four 8-Speed drivetrain, making it a superb bike for XC trail riding and all-day epics at the bike park.
Comfortable and Agile Geometry
Don’t be fooled by the price point, the Nucleus isn’t your run of the mill entry-level mountain bike. It’s the foundation of the Vitus mountain bike range, with aggressive geometry designed to get you hooked. Don’t say we didn’t warn you. For 2021 all models now come with 1x groupsets.
Box Four 1x Drivetrain and Tektro Disc Brakes
The low, long, and slack geometry is coupled to 120mm of Suntour Air suspension taking care of any rough terrain you’ll encounter on the trails while the Tektro M275 brakes will give you ample stopping power. For 2021 the Nucleus has received a threaded bottom bracket for increased durability and a wide range groupset thanks to the new Box Four drivetrain. A clutch activated rear mech, and a narrow wide 1x chainring up front will keep you on the trails all day.
WTB Rims and Tyres
Vitus’ tried and tested combination of WTB tyres and rims offers superior performance and grip. Finished off with a combination of Vitus and Nukeproof components the Nucleus 29 VR has stepped up to take your riding to the next level.

I have been a long term customer of Chain Reaction but was disappointed with this most recent interaction. The delivery was slow (understandable given tricky conditions) and there was no update as to a new delivery date etc. I had to do all the chasing for info myself. When my bike did arrive, it was not at all well set up with calliper alignment especially way off and the top tube had a deep and wide scratch. The checklist was fully ticked but I strongly doubt it was actually looked at.

I needed a replacement for my tired GT Avalanche but didn’t want to spend loads. Found this gem that looked really smart and right within my budget but also didn’t look it was made of cheap parts. I took it for a short spin around the local trails and I’m happy with the outcome and performed well up/down steep muddy hills as well as through woodland tracks. The build seems solid as well as the parts, well worth the money. Can’t wait to take it on more grueling trails and try out some jumps.

The bike is fantastic value for money and I can say I couldn’t fault it.

Coming from a 26″cube i can’t believe the difference in ride.
It was this or a trek roscoe 8, after reading the reviews im happy I made the right choice.
The bigger wheels paired with the big volume tyres mean I roll over obstacles with ease.
Brakes are responsive and the single ring up front makes for easy changes.
Frame protection is a must but the blue paint actually looks black
Just a heads up, Pedals supplied aren’t the best.
Dropper post needed and I’m sorted.
Buy the bike, you won’t be disappointed.
Ride safe all.

It’s a good bike, And I liked it immediately although there are a couple issues. First, the deraulier out of the box skips over the 7th gear, but other than that the deraulier seems fine. On my first day of riding the tube has already popped. It was stock pressure, so it wasn’t a pinch flat, it just popped, and no one has an tubes. I would definitely recommend this but but the deraulier issue could he hard to fix, although it could also just be ignored because it works fine even though it skips over it.

Recently purchased a Vitus Nucleus 27 vr – Came out of the box easy. Assembly easy. Riding it is easy! Looking at it is easy – it looks very cool. Love it. Watch the video on the site for assembling the bike. Only problem was some things that came in the box, and I have no idea what there are for. One is a a clear round thing that looks like a chain guard. Not in the instructions. The others are sticker looking things. Again, nothing in the instructions about where they go or what they are. Frankly, I don’t care about either because they don’t appear to effect the performance of this sweet bike. Its just a little disappointing there is no mention of either, anywhere. A bit sloppy.
