Vitus Nucleus 27 VR Bike (Altus 2×9)

Sitting at the foundations of the Vitus range, the Nucleus has never been an ordinary entry-level mountain bike. It features a quality construction, solid spec list and an increased stand over height with aggressive geometry that’s designed to get your blood pumping as you hit the trails. Vitus’ number one, best-selling hardtail, the Nucleus has won MBR’s under £500 hardtail of the year for the last four years running.

SR Suntour Suspension, 2×9 Shimano Gearing and Hydraulic Disc Brakes

With its low, long and slack geometry, the new Nucleus 27 VR’s ride versatility is increased via 120mm of Suntour fork travel, Tektro hydraulic disc brakes and large volume WTB tyres on wide rims for outstanding rolling performance and grip. Plus, it’s equipped with a reliable and precise shifting 2×9 drivetrain from Shimano, a Vitus finishing kit and dropper post routing for easy installation of a dropper post upgrade in the future. This is a hardtail that’s built to take your riding to the next level and does so without breaking the bank.
