Vitus Bikes Nucleus 275 Hardtail Bike

Ready to step up to the challenge of off road riding? Meet the Nucleus range of trail centre inspired hardtails; the perfect introduction to proper mountain biking with lightweight aluminium frame and exceptional components package! The Nucleus 275 brings the new 27.5” (650b) wheel size to the masses with improved performance at entry level price!  Additional features include Suntour XCR suspension forks, Shimano Alivio shifters and derailleurs with Tektro hydraulic disc brakes and all for for less than £600! The Nucleus 275; performance and style in a great value package!

Lightweight Mechanical Formed 6061-T6 Aluminium  Frame & Suntour XCR Fork

A lightweight 6061-T6 aluminium frame provides a bombproof chassis for trail centre assaults with great upgrade potential for fitting a chainguide thanks to the ISCG tabs. Our aggressive trail geometry has been designed around 27.5” (650b) wheels and a 120mm travel fork; a short headtube and low bottom bracket keep the centre of gravity low to provide improved handling whilst the larger wheel size offers improved performance and handling. Suntour XCR Air forks feature hydraulic Lock-Out & Rebound adjustment with 120mm of air sprung travel. A tapered alloy steerer and 32mm stanchions provide a stiff front end for precise steering and predictable handling.

Shimano Alivio & Suntour Groupset

Shimano Alivio shifters and derailleurs provide slick performance at entry level pricing; the Suntour XCM triple chainset will provide a wide range of gears that will cope with any ascent the trails can throw at you. If fast paced singletrack assaults are your thing you need to have confidence in your brakes and on this front the Tektro HDC330 hydraulic disc brakes won’t disappoint!

Vitus Wheelset & Finishing Kit

Vitus provides the wheels and finishing kit for the Nucleus range of bikes. The Nucleus 275 features SRAM MTH-306 disc hubs on Vitus double wall alloy disc rims. Continental X-King tyres provide surefooted handling and low rolling resistance. Finishing kit is supplied by Vitus with our lightweight 6061 alloy stem, bars and seatpost providing high performance components which have been colour coded to match the frame decals.

Rated 5 out of 5 by outstanding value I think For the money you wont find a better deal! An absolute bargain,and a free goodie bag. I was looking at the rockrider 8.1 but this in my opinion is much better and for 429,nice 21 July 2014
Rated 5 out of 5 by Great quality,Looks amazing Just received the bike ordered 2 days ago so not a bad service atall! Upon unboxing it I couldn't believe how well made the bike is, A super light frame and really nice wide handle bars make it look really aggressive along with the squared off top tube. Also really quick time to get it built up, just had to attach the bars and fit the pedals I ordered with the bike (Shimano saints were what I brought as they are a great pedal and cheap on here! Also pedals are suplied with the bike ) Took it out over the local trail and it rode great, smooth gear changes as the guys a CRC set up the gearing before hand! Honestley The pics you see online really don't do it justice. Simply great looking bike. Get it! 11 July 2014

Rated 1 out of 5 by Huge dissapointment Really excited at the purchase of my first 'proper' mountain bike. Bike arrived in a really quick time which impressed me. All that was left for me to do was to fit the peddles and handlebars. I used it for a couple of weeks to commute to work and get used to the gears, brakes and wide hadlebars which gave a very different feel to my usual riding position. I was really pleased with my purchase and looking forward to my first off road mountain biking session at Dalby. Unfortunately I have returned from Dalby very disappointed. I have no rear brake and the rear mech is stuck. I took it to my local cycle shop who have given it a real negative report saying it wasn't up to the usual high standards of chain reaction and is poorly put together. I am awaiting a response from the warranty team and they may tell me this has been a one off. I shall update anyone who reads this asap. 16 June 2014
Rated 5 out of 5 by Great bike! Just received my bike bike today (was ordered last week) with a very good package! I am too excited to try it that is why I purchase along with the bike, a pair of pedals also from chain reaction. But, the package for pedals have not arrived yet. Perhaps today :). But that give me time to read some manuals included, on top of my excitement! To make me a safer rider. Could not wait for the pedals and try this great bike out! Thanks CRC!! 28 May 2014
Rated 3 out of 5 by Montagemängel Ein an und für sich für den Preis ordentlich ausgestattetes Bike. Ich habe es mir bestellt und es wurde sicher verpackt und schnell versendet. Lediglich Lenker und Pedale montieren, letztere sind aber nicht im Lieferumfang. Schon bei der der Montage des Lenkers stellte ich ein Spiel des Steuersatzes fest. Ein nachziehen der Schraube brachte nichts, das Spiel stellte sich nach kurzer Fahrt immer wieder ein. Desweiteren hatte nach keinen 10 km das Lager des Hinterrades erhebliches Spiel. Beides ließ ich in Deutschland in einer Fachwerkstatt checken und auf meine Kosten beheben, da es mir gegenüber eines hin- und hergeschickes als geringere Übel schien. Die Diagnose war ein defekter Lagerring im Steuersatz, was wahrscheinlich auf schlechte Montage zurückzuführen ist und ein mangelhafte Montage der hinteren Nabe. 26 May 2014
Rated 5 out of 5 by Great deal, great service and great product! Having set myself a budget of £600 for a hardtail MTB with 27.5 wheels, I searched and compared many and decided it was a toss up between a CUBE and the Vitus Nucleus 275 which were the same price. I opted for the Vitus as CRC offered 20% off (£120) which I couldn't ignore. Once purchased (wednesday evening) the bike was in the care of Parcelforce by Friday morning on a 48hr delivery service (free of charge). Bike was delivered the following Wednesday opposed to the expected Monday because of a Parcelforce mistake. The bike turned up in a sizeable box undamaged and neatly packaged. Once opened up all I have to do was attached the already plumbed in handle bar and screw on the pedals (which are not supplied), as the brakes and gears were already setup to ride, bonus! All in all the Vitus Nucelus 275 is a stunning looking bike with a beautiful, quality finish and half decent parts from the likes of Shimano and Suntor and all for £480 this bike is a great deal by any means. Oh and the bag of freebie treats courtesy of CRC was a neat surprise. 18 May 2014
