Koryak Di2 Stem

What Our Gearhead® Experts Are Saying:

"I specced the PRO Koryak Di2 Stem on a trail build running a Di2 drivetrain and the difference in cockpit cleanliness compared to an external routing setup is immediately obvious. The internal cable routing keeps everything protected from trail debris and out of the way, and the 3D forged AL-7075 construction gives the stem a stiffness and precision feel that suits the rest of the build perfectly. The plus or minus six degree rise made dialing in the bar height straightforward without needing to swap stems."

Electronic drivetrains deserve a cockpit built around them, not retrofitted to accommodate them. The PRO Koryak Di2 Stem was designed specifically for riders running Di2 who want the cables routed cleanly through the front end rather than zip-tied along the outside of it. Used with a PRO BTR Expander, Di2 cables route internally through the stem, keeping them protected from trail debris and out of the way on technical terrain where snagging a cable is the last thing you want to deal with.

The stem itself is forged from 3D AL-7075 aluminum and CNC machined to remove excess material, delivering a light and stiff platform that handles the demands of trail and all-mountain riding without compromise. A plus or minus six degree rise gives you meaningful bar height adjustment at installation, the two-bolt steerer clamp handles 1-1/8 inch forks securely, and the four-bolt removable faceplate makes handlebar swaps and adjustments clean and straightforward. At 100mm in length it suits a wide range of trail and all-mountain frame geometries and rider positions.
