Nukeproof Horizon Bottom Headset Cup Nukeproof have launched a range of headset's which use the titanium coated race bearings with stainless steel balls. The titanium coating is applied using “ Physical Vapour Deposition” which means that the material is vapourised in a vacuum environment & then deposited on the bearing races as a composition coating. This process allows the structure, density & stoichiometry of the coating to be controlled allowing the exact attributes in our design brief to be achieved. The coating is 0.000118” thick & has a molecular bond to the bearing races so it won't wear off or corrode. The bearing is ABEC 5 certified which means that it has passed tests which include ID & OD tolerance's, roundness of ball, trueness of faces & surfaces aswell as noise testing at high RPM making it the perfect bearing for use in a headset. These bearings have been designed for use in the harshest weathers & have went 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.
