Lewis FX High Intensity Aluminum Stem

Lewis FX CNC Stem

Extreme precision, maximum control, and DH-inspired stiffness in a lightweight 35 mm cockpit stem.

The Lewis FX CNC Stem is built for riders who want sharp steering response, front-end stiffness, and long-term durability without the extra weight of a full downhill-only cockpit setup. Precision-machined from 7075-T6 aluminum and assembled with stainless steel bolts, the FX is designed to deliver confident handling for aggressive trail, enduro, and high-speed descending.

With a 70 mm clamping width, 35 mm handlebar bore, and a reinforced single-end locking design, the FX Stem is engineered to improve cockpit rigidity while also distributing clamping forces more effectively across the bar. The result is a more planted steering feel, better front-end precision, and reduced stress at the handlebar interface for improved long-term reliability.

Key Features & Benefits

• CNC-Machined 7075-T6 Aluminum: Premium aluminum construction provides an excellent strength-to-weight ratio for aggressive riding without unnecessary bulk.
• Reinforced Single-End Locking Design: Designed to increase end-face strength and reduce stress concentration, helping improve durability and installation consistency.
• Larger Stainless Steel Hardware: Oversized bolt design helps increase stem rigidity and maintain a more secure clamping interface under hard riding loads.
• 70 mm Clamping Width: Wider than many standard stems, helping deliver a stiffer and more stable front-end feel for precise steering at speed.
• 15 mm Contact Width: Wider unilateral contact surface helps reduce stress between the stem and handlebar, which may support bar longevity and improve load distribution.
• 35 mm Bar Clamp: Built for modern oversized cockpit setups where steering precision and front-end stiffness are priorities.
• Trail-to-Enduro Ready: Designed for riders who want DH-style steering confidence in a lighter package suited for aggressive trail and enduro use.

Ride Feel & Performance

• Fast, precise steering response
• High front-end stiffness for aggressive riding
• Stable handling at speed
• Lightweight construction with gravity-oriented strength
• Well suited for trail, enduro, and technical descending

The Lewis FX Stem is made for riders who want a direct, confident steering feel without giving up the lighter weight and responsiveness expected from a modern aggressive trail or enduro build.

Why a Wider Stem Clamp Matters

A wider stem faceplate and clamp area can help improve front-end rigidity and distribute clamping forces more evenly across the handlebar. For riders pushing hard through rough terrain, cornering aggressively, or riding at speed, that can translate to a more controlled and predictable cockpit feel. The Lewis FX CNC Stem is designed around that principle, combining a wider clamp profile with premium materials to deliver a more stable and confidence-inspiring ride feel.
