The Vitus Nucleus is the mountain bike you never forget. The one that got you hooked. It’s everything a mountain bike should be – comfortable, reliable and predictable. But above all, it’s fun. The Nucleus is versatile enough to ride anywhere, but you’ll have the best time riding proper trails. It feels just like a mountain bike should, a bike that inspires confidence when riding off-road, over rough ground and when tackling trail obstacles. This is a real mountain bike and a proven performer, but don’t just take our word for it, the Nucleus is a multi award-winner that has been voted £500 Hardtail of the Year four times in a row by MBR Magazine. Riding your first mountain bike requires full trust in the equipment. As the trail twists and turns, rises and falls, you need to feel in complete control. The tried and tested geometry of the Nucleus has reassuring stability and agility that keeps your body relaxed and your smile wide. To match, the bike arrives equipped with high-quality, durable components. The components include Clarks M2 hydraulic disc brakes that are responsive no matter the conditions, a terrain-smoothing SR Suntour XCR32 Boost air-sprung suspension fork and the wide-range Shimano Deore drivetrain to ensure the gear shifting is fast and light. With an award-winning aluminium frame at its core, this bundle raises the stakes adding a Brand-X Ascend Dropper Seat Post (fully fitted) for on-the-fly saddle height adjustments, helping you always find the right position on the bike and grippy Nukeproof Neutron EVO Pedals that’ll keep your feet firmly planted in place. Key upgrades that’ll help grow your confidence on the bike and keep your mountain biking skills rolling forward. Your first mountain bike should arm you with everything required to enjoy this sport. To set you on your way to unlocking the excitement of riding trails. The Nucleus is not off-the-shelf, it’s tailored specifically for the needs of a new mountain biker.
