Nukeproof Warhead Mix & Match Top Cup

New additions for 2015 include the option to select specific TOP and BOTTOM headset cups to suit your headtube and fork configuration.

The NEW cups will allow you to replace the bearings only with the Nukeproof Steel Bearing, or upgrade to a ceramic headset by simply purchasing the Warhead Ceramic Headset Bearing.

Precision-engineered to the most exacting of tolerances to deliver optimum performance and long life in harsh riding conditions.

The latest 2015 generation of Warhead MTB headsets have been revised, improved and expanded for optimum fit, sealing and performance as well as compatibility with a wide range of fork and frame standards. Featuring sealed angular contact bearings, split 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 all riding disciplines.

The Warhead is available in a range of options to cover multiple fork/headtube configurations, including full range of Standard Steerer (SS – 1-1/8") and Tapered Steerer (TS – 1-1/8" to 1.5") combinations. Internal and external cup options also available including zero stack versions with internal top and bottom cups. In addition; the Nukeproof Reducer Crown Race allows easy conversion from 1.5" to 1 1/8th (2015 onwards).

The specialist AS1 complete headset with 1 degree internal angle adjustment for 1.5" headtubes.

All models feature a super tough black hard anodised finish, with laser-etched graphics.
