The Nukeproof Horizon Stem is the newest addition to the Nukeproof cockpit component range. Developed alongside Nukeproof pro athletes and staff, the Horizon stem has been tested in the most demanding Enduro and Downhill conditions; Nukeproof has optimised this stem to be lightweight and ultra-strong.

Precision CNC Machined for Strength and To Reduce Weight

The stem can be mounted either way, providing 5mm of bar height adjustment, thus allowing you to tailor your cockpit set up with 5mm rise or fall. It has been precision CNC machined to maintain high strength and to remove unnecessary material to save weight and give a sleek modern, stylish look.

Offset Design for Durability and Easier Fitting

The Horizon stem steerer clamp features an offset design, which provides maximum thread contact for the steerer bolts. All sharp edges have been removed during the machining process to ensure a smooth feel while eliminating any risk of injury should your body come in contact with the stem. The face plate has also been designed specifically with “no gap” at the top to give it a clean look and to make fitting assembly easier.

The fitting instructions for this stem can be found HERE for your convenience and is also included within the stem packaging.
