The Vitus Nucleus is the 4x winner of MBR magazine £500 Hardtail of the Year award. This 27 VRS model is agile and fast aboard 27.5" wheels and features a Shimano Deore 1x10-Speed groupset with an 11-46T wide-range cassette and hydraulic disc brakes. Ideal for XC riding and trail centre all-day epics, this hardtail provides a versatile and dependable performance anywhere.
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 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 Shimano 1x10 M5100 Deore groupset. A clutch activated rear mech, and a narrow-wide 1x chainring upfront will keep you on the trails all day.
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 27 VRS has stepped up to take your riding to the next level.
