Lewis FX High Intensity Aluminum Stem

Lewis FX CNC Stem — Extreme Precision.  Maximum Control.  Zero Compromise.

The Lewis FX Stem is engineered for riders who demand downhill-level strength without sacrificing weight or responsiveness. Precision-machined from 7075-T6 aluminum and secured with stainless steel bolts, the FX delivers an extraordinary handling experience whether you’re smashing enduro stages, sprinting out of berms, or dropping into high-speed descents.

Designed around a wider 70mm clamp interface and reinforced single-end locking system, the FX Stem gives you the stiffness of a DH stem with the lightweight feel of a trail setup—all while reducing stress on your handlebars for longer life and better ride quality.

Key Features

CNC-Machined 7075-T6 Aluminum

A premium-grade alloy chosen for its exceptional strength-to-weight ratio. The FX stem maintains downhill stiffness at a trail-friendly weight.

 

Reinforced Single-End Locking Design

One-sided locking increases end-face strength and reduces stress concentration caused by improper installation—enhancing long-term reliability.

 

Larger Bolt Design

Non-locking end faces use enlarged stainless hardware to improve stem rigidity and prevent unwanted flex under load.

 

70mm Clamping Width

3–4mm wider than typical upright stems, delivering DH-level stiffness and unmatched front-end precision at high speed.

 

15mm Contact Width

A wider unilateral contact surface reduces stress between stem and handlebar, protecting your bar and increasing overall lifespan.
