Nukeproof Sam Hill Horizon Stem

The Nukeproof Horizon Stem is the newest addition to the Nukeproof cockpit component range. Developed alongside Sam Hill, Nukeproof sponsored 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 and this Sam Hill Signature version also comes with Ti bolts and is finished off with Sam’s signature logo laser etched into it.

Precision CNC Machined

The stem can be mounted either way, providing 5mm of bar height adjustability 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.

Modern MTB Stem with a Clean Look

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.
