Vitus Nucleus 29 VR Mountain Bike – Grey

The Vitus Nucleus is the 4x winner of the MBR magazine £500 Hardtail of the Year award. This 29er is a superb value for money bike but it’s kitted out with great components aboard a quality frame, giving more performance than you would expect from a bike at this price-point. And, with SR Suntour suspension and a Box Four 8-Speed drivetrain, the Nucleus 29 VR is ideal for XC, trail 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 Disc Brakes

The low, long, and slack geometry is coupled to 100mm of Suntour Air suspension taking care of any rough terrain you’ll encounter on the trails while the disc 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.
