Product Details

Overview & Technology

Engineered for lightness and precision. The FSA Energy stem is 3D forged from AL2014 and CNC machined to final tolerances, delivering a high strength-to-weight ratio and a refined surface finish. The sculpted 4-bolt faceplate evenly distributes clamp forces across 31.8mm handlebars while keeping material use to a minimum. Titanium hardware and a shallow 40mm stack height reduce weight and resist corrosion, giving a total weight of just 113g for the 100mm length. The 6° angle and stiff construction translate rider inputs into immediate steering response — ideal for road and fast gravel use where precision matters.

Key Features & Benefits

Premium construction: AL2014 alloy offers higher fatigue strength than common 6061 stems, while 3D forging optimizes the grain structure for durability. CNC machining refines clamp surfaces and faceplate geometry for repeatable fit and finish. • 4-bolt sculpted faceplate: Smooth pressure distribution minimizes stress points on alloy and carbon bars. • Titanium bolts: Lower mass and superior corrosion resistance compared with steel hardware. • 40mm stack height: Sleek cockpit profile that works well with modern low-stack headsets and integrated systems.

Fit, Compatibility & Specifications

The Energy stem clamps contemporary 31.8mm handlebars and fits a 1-1/8" steerer tube. Available lengths include 80mm, 90mm, 100mm, and 110mm to dial in reach and handling. The stem angle is 6°, which gives a modest rise while keeping the cockpit low and aerodynamic. Pay attention to torque specs when installing: follow handlebars and headset manufacturer's recommended torques, and use a calibrated torque wrench. While the faceplate design is carbon-friendly, always check the handlebar maker's torque limit before installation.

Who It's For

The FSA Energy stem is aimed at road riders and fast gravel enthusiasts who want a lightweight, precise, and clean-looking cockpit component. Climbers, racers, and riders upgrading stock components will appreciate the weight savings and responsive steering feel. If you run a modern 31.8mm bar and a 1-1/8" standard steerer, and you value low mass without sacrificing stiffness or reliability, the Energy stem is a high-value upgrade.

Frequently Asked Questions

Will this stem fit my 31.8mm handlebar?

Yes — the FSA Energy is designed for standard 31.8mm diameter handlebars. Make sure to align the faceplate and tighten bolts to the handlebar manufacturer's torque specs to avoid damage.

Is the stem safe for carbon handlebars?

The sculpted 4-bolt faceplate distributes clamp load well, but you must follow the carbon handlebar maker's recommended torque limits and use carbon assembly paste if advised. Do not exceed torque specs.

What is the weight for lengths other than 100mm?

The listed weight of 113g applies to the 100mm length. Other lengths will vary slightly; expect small differences (a few grams) between 80mm, 90mm and 110mm due to material variation.

What torque should I use on the faceplate bolts?

Refer to FSA or the bolt manufacturer's recommended torque — typically around 5–6 Nm for titanium faceplate bolts on alloy stems, but always check the specific torque printed in the stem documentation and on the bolts.

Can I use this stem with an integrated headset or low-stack system?

Yes. The 40mm stack height and 6° angle suit low-stack headsets and modern integrated headtube designs. Confirm steerer tube length and headset spacers before installation to ensure proper top cap compression.

Is the stem suitable for gravel and rough roads?

Yes — the AL2014 construction and 4-bolt faceplate offer a good balance of stiffness and impact tolerance for road and gravel riding. For aggressive off-road or enduro use, consider gravity-specific components with different design priorities.

Buying Guide

Choosing the right stem length and angle changes bike handling more than many riders expect. Shorter stems (80–90mm) increase steering responsiveness and are common on tight, technical road or gravel courses; longer stems (100–110mm) stretch the cockpit and stabilize high-speed riding. The Energy's 6° angle gives a mild rise, making it versatile for riders who want a slightly more upright position without sacrificing aerodynamics. Consider materials and construction: AL2014 with 3D forging and CNC machining gives a stronger and lighter structure than generic cast stems. If you're switching from a heavier stock stem, pay attention to handlebar and headset torque limits and re-check bolts after your first rides for safety and optimal performance.
