Vitus Nucleus 275 VRS Mountain Bike

The foundation of the Vitus range, the Nucleus is no ordinary entry-level mountain bike. Its solid spec list, increased standover clearance and aggressive geometry is designed to get you hooked. Vitus’ number one, best-selling hardtail, the Nucleus has won MBR’s under £500 hardtail of the year three years in a row.

The low, long and slack geometry of the Nucleus 275 VRS Mountain Bike boasts 120mm Suntour Air forks, Tektro hydraulic disc brakes and large volume WTB 29mm tyres on wide rims for awesome grip. Also, it’s kitted out with a reliable Shimano 2×9 drivetrain, a Vitus finishing kit and dropper post routing for easy installation of a dropper post should you require this beneficial upgrade in the future. This is a hardtail that’s built to take your riding to the next level.
