Nukeproof Mix & Match Bottom Headset Cup

Nukeproof headset’s are now available as separate top and bottom cups allowing you to easily choose the options you require.

The cups will allow you to replace only the bearings with the Nukeproof Steel Bearing. Precision-engineered to the most exacting of tolerances to deliver optimum performance and long life in harsh riding conditions.

The latest generation of 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 headset offers the optimum balance of light weight, strength and durability for performance across all riding disciplines.

The headset 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.

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