The PRO Koryak stem gives all-mountain, trail and cross-country riders a stiff, dependable cockpit connection that holds your bars exactly where you set them. Forged from 7075 aluminium and CNC-machined to trim excess material, it pairs a confident, planted front end with a clean, purposeful look. The 100 mm length with a reversible +/-6° rise lets you fine-tune reach and bar height to dial in your fit.

Highlights

  • Precise, predictable steering thanks to a rigid 3D-forged 7075 alloy body
  • Reversible +/-6° angle so you can run it rise-up or rise-down to set bar height
  • Four-bolt Headlock faceplate keeps your bars clamped securely and evenly
  • Oversized 31.8 mm bar clamp reduces flex under hard efforts and rough terrain
  • Durable anodised finish for everyday trail use

Built to stay put

The Headlock four-bolt front clamp spreads load across the faceplate for a secure, even grip on the handlebar, while the squared, 3D-forged construction adds lateral rigidity where it counts. The result is direct, fuss-free handling whether you are picking lines on technical trail or putting down power on a climb.

Adjustable fit

Because the +/-6° angle is reversible, the same stem can sit with the rise pointing up for a taller, more upright position or flipped down for a lower, more aggressive stance. At 100 mm it suits riders wanting a slightly longer reach for stability and control.

  • Bar clamp: 31.8 mm handlebars
