Welcome to the Vitus Nucleus, 4 x winner of MBR magazine £500 Hardtail of the Year.
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.
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 or Clarks M2 brakes will give you ample stopping power. For 2021 the Nucleus has received a threaded bottom bracket for increased duribility 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.
Our 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 Nucleys 27 VR has stepped up to take your riding to the next level.
*Due to volatility in the bicycle supply chain we may slightly alter the specification of the component parts supplied with this bicycle. Where this happens we have listed the alternate product in the specification table and have ensured that this is of either equivalent or superior specification to the stock component.
