Lightweight Mechanical Formed 6061-T6 Aluminium Frame & Suntour XCR Fork
A lightweight 6061-T6 aluminium frame provides a bombproof chasis 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 deraileurs 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.
