  • Nukeproof Horizon Bottom Headset Cup

    Nukeproof's headsets feature titanium-coated race bearings with stainless steel balls. The titanium coating has been applied using a method called 'Physical Vapour Deposition,' (PVD) which helps to improve durability and overall structure and density of the bearings. Incredibly fine, this coating is only 0.000118” thick and won't be damaged with wear or tear or corrode, thanks to the molecular bond from the PVD method. Whatsmore the race bearings have been ABEC 5 certified, making it the ideal addition.

    These bearings have been designed for use in the harshest weathers and have gone through various tests by the Nukeproof team during development so they are 100% confident in their performance. To back this up Nukeproof are offering a 5-year warranty on these headsets so you can be reassured your purchase will be a good one. 

    All models feature a super tough black hard anodised finish, with laser-etched graphics.
