Easton EA50 Stem 31.8 – 80mm – ±17°
The Easton EA50 Stem 31.8 80mm ±17° is a lightweight, entry-to-mid level road/MTB stem designed for riders who want a strong, reliable, and adjustable cockpit setup at a reasonable price.
It uses a 31.8mm handlebar clamp, a 1-1/8” steerer clamp, and comes in an 80mm length with ±17° rise options for tuning riding position.
What It Is
A forged aluminium stem from Easton’s EA50 range, used to connect your handlebar to your fork steerer tube.
The 17° angle option allows you to flip it:
- Upwards → more upright, comfortable riding position
- Downwards → more aggressive, aerodynamic position
Key Features

- 31.8mm handlebar clamp (modern standard size)
- ±17° reversible angle for fit adjustment
- 80mm length (balanced reach for XC, road, and gravel setups)
