Nukeproof Warhead 44IISS-DC Headset

We have totally overhauled our headset line to keep them up with the evolution of mtb frame and fork design and the emergence of new headtube/fork steerer standards.

Precision-engineered to the most exacting of tolerances to provide the optimum fit between headset and frame, the latest generation of Warhead headsets promise the same fit-and-forget performance as their predecessors but now offer compatibility with traditional and emerging standards.

Featuring sealed angular contact bearings, alloy crown races and upper and lower bearing cups CNC-machined from proprietary aluminium, the Warhead headset offers the optimum balance of light weight, strength and durability for performance across a range of riding disciplines.

All are finished in a super tough black hard anodised finish, with laser-etched graphics.
