DETAIL GALLERY:
For 2011, 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. We've added 1.5in, taper steerer and internal zero stack headsets to our range, along with a world first headset allowing 1.5in steerer fitment in a 44mm ID headtube.
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.
