FSA Energy Bicycle Stem

AL2014 is a high-strength aluminum alloy that allows the stem to be both lightweight and exceptionally stiff. By using this material alongside precision CNC machining, FSA achieves a weight profile that competes with carbon fiber options without sacrificing structural integrity.

This stem is designed for a 31.8mm handlebar clamp diameter, which is the current industry standard for most modern road bikes. If you are unsure of your current bar size, it is usually printed on the center section of the handlebar near the stem clamp area.

Yes, the titanium hardware is primarily used to shed grams compared to standard steel bolts. Beyond the weight savings, titanium is highly resistant to corrosion, ensuring the bolts remain easy to adjust and maintain over time.

The stack height is 40mm. This measurement is important because it dictates how much of your steerer tube the stem will cover; you need to ensure you have enough steerer tube length remaining on your fork to accommodate this height.

While the FSA Energy is engineered specifically for road cycling, its 3D forged construction and stiff design make it capable of handling light gravel use. However, if you are riding aggressive, rough terrain, you might prefer a stem specifically reinforced for the rigors of gravel or mountain biking.
