Nukeproof Warhead Stem

The Nukeproof Warhead stem is built to take the toughest of DH punishment and yet weighs in light enough for XC racing, Enduro-style events or general riding.

Custom-manufactured from high-grade 6061 aluminium to the most exacting of standards and featuring a cold-forged construction for optimum strength, the Warhead stem is extensively CNC machined to shave off excess material without compromising structural integrity and features micro-fluting to help dissipate stress loads.

It features an OS 31.8mm diameter bar clamp with a four-bolt faceplate system providing maximum security against bar slippage, while opposing bolts on the steerer clamp help to evenly distribute the clamping forces on the steerer and a knee-friendly design eliminates protruding edges.

Various length and colour options - to cater individual rider preferences.
