Take command of your e-MTB's front end with a stem built for the extra mass and torque of an electric trail bike. The PRO Koryak E-Performance Alloy stem keeps your steering precise and planted, so you can point and shoot through rough terrain with confidence.

Highlights

  • Dedicated e-MTB stem engineered for the demands of heavier, higher-torque electric trail bikes
  • Stiff 6061 aluminium body for direct, predictable steering
  • 45mm length and 0-degree angle for a balanced, modern trail position
  • Oversized 35mm handlebar bore for extra control and vibration damping
  • Designed to pair with the PRO Koryak E-Performance handlebar for a complete cockpit

Built for e-MTB

Electric mountain bikes carry more weight and put more load through the cockpit, so the Koryak E-Performance is shaped with a robust, oversized profile to match. The 6061 aluminium construction delivers the stiffness you want when muscling a heavier bike through corners and over obstacles.

Control and comfort

The 35mm handlebar clamp works with oversized 35mm bars to sharpen steering response while helping take the edge off trail buzz, keeping your hands fresher on long descents.

Compatibility & fit

This is the 45mm length with a 0-degree angle. It clamps 35mm-diameter handlebars and fits a standard 1-1/8" (28.6mm) threadless steerer. For a matched setup, combine it with the PRO Koryak E-Performance handlebar.
