Vitus Nucleus 27 VR Alloy Hardtail Mountain Bike 2021

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.
