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 and then deposited on the bearing races as a composition coating. This process allows the structure, density and stoichiometry of the coating to be controlled allowing the exact attributes in our design brief to be achieved. The coating is 0.000118” thick and 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 and 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 and 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.
