Lewis FX High-Intensity Stem

Stiff, strong, and confidence-inspiring. The Lewis Aluminum Stem FX is purpose-built for aggressive trail and enduro riders who demand pinpoint handling and rock-solid durability. Crafted from premium 7075-T6 aluminum and precisely CNC-machined, this stem delivers an outstanding stiffness-to-weight ratio, ensuring your cockpit stays responsive and predictable even on the roughest terrain.

The FX features a modern 35 mm bar clamp designed for today’s oversized handlebars, 40mm length, with a 70 mm wide mating surface. The four-bolt faceplates use oversized bolts to distribute clamping forces evenly to protect your bars and keep everything securely in place. Subtle chamfered edges and a durable anodized finish add a clean, premium appearance worthy of any high-end mountain bike build.

For even more confidence, the FX incorporates a no-gap top faceplate for straightforward and consistent handlebar torque settings. Its wider 70 mm clamping width, 3-4 mm broader than typical upright stems, boosts rigidity for precise control during high-speed descents. Each faceplate mount was widened to 15 mm, reducing stress concentration at the interface between the stem and bar and extending the service life and risk of damage to carbon handlebars.
