PRO Koryak Stem

Koryak Stem delivers precise MTB control with lightweight alloy strength

What Our Gearhead® Experts Are Saying:

"I’ve run the Koryak stem on both my trail and XC bikes, and it delivers rock-solid control without any excess weight. The Headlock system is confidence-inspiring—especially on rugged terrain—and the 3D-forged construction keeps things light and stiff."

When we’re weaving through tight switchbacks or hammering through chunky descents, control starts at the cockpit. The PRO Koryak Stem gives us a lightweight, responsive connection between bar and steerer that holds steady under pressure. Designed for all-mountain, trail, and cross-country riders, it blends durability and precision for a refined ride feel on any terrain.

Crafted from 3D-forged aluminum alloy, the Koryak is built to minimize flex and maximize power transfer. Its Headlock front clamp system offers a secure, slip-free hold on the bars, even during hard braking and sharp transitions. Whether we´re fine-tuning our fit or building a fast and reliable setup, this stem delivers clean aesthetics, dependable strength, and dialed-in steering for all our trail missions.
