Nukeproof Horizon Top Headset Cups

Nukeproof Horizon Top Headset Cups

Nukeproof headsets are now available as separate top and bottom cups allowing you to easily choose the options you require. This version uses high-end bearings with Ti coated races and stainless balls.
The bearing is ABEC 5 certified which means that it has passed tests which include ID and OD tolerance’s, roundness of ball, trueness of faces & surfaces as well as noise testing at high RPM.

These bearings have been designed and tested for the harshest of UK winters so if you want bearings that won’t let you down then these are the ones to get.

These 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.

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

A top cap and star nut are also included.

Nukeproof are so confident in the performance of these bearings that they are offering a 5 year warranty so you can be rest assured your purchase will be a good one.
