The previous model of the Nucleus was awarded MBR’s “£500 Hardtail of the Year” award and this only encouraged Vitus to try and improve the Nucleus further still. It's the ideal choice for those who are just getting into mountain biking and want to progress their skills, as the Nucleus V benefits from a refined, trail-orientated frame geometry. The frame now has a longer top tube and is lower and slacker than before and offers an improved stand-over clearance.
To accommodate the modern trend towards adjustable saddle height on the go, the frame also has internal routing points for a dropper seat post.
Rest assured that each bike is fully built, tested and tuned by Wiggle's team of qualified bike mechanics to ensure your bike arrives in perfect condition. Find out which size fits you by clicking the size chart tab.

Getting the Right Fit
At Wiggle we measure each of our bikes to build accurate size charts for our customers. Our qualified team of mechanics then individually check each order, against measurements supplied by you, to ensure the size chosen is correct. Another reason you can have complete confidence when buying a bike from Wiggle!
If you are on the change over between sizes both options will fit. Racers and experienced riders would usually select a smaller size as this offers quicker handing. A larger bike offers more stability and is more suited to new and intermediate riders.
