Easton | EA90 Stem

The connection between your hands and every move the bike makes.

The Easton EA90 is a lightweight alloy stem designed for responsive handling across road and gravel.

Its enlarged boom diameter increases stiffness for more direct steering, while Easton’s high-grade alloy construction removes unnecessary material to keep weight down. At approximately 120g in the 100mm length, it delivers a strong balance of low weight, control, and everyday durability.

The TopLock faceplate simplifies handlebar installation, while Easton’s ICM system places a Garmin computer mount directly in front of the stem for a cleaner cockpit.

Important Compatibility Note

Compatible with:

• 31.8mm handlebars
• 1 1/8-inch threadless steerer tubes

The stem has a reversible ±7° rise. Confirm the required stem length and orientation before ordering.
