Syncros RR 1.5 Stem

RR 1.5 Stem delivers clean integration and easy adjustability for road precision

What Our Gearhead® Experts Are Saying:

"I’m super impressed by the RR 1.5 Stem. Its clean aesthetics, great stiffness, and the internal cable routing are a dream. I love that I can swap stem lengths without needing to cut brake hoses, especially when dialing in fit on aero builds."

Whether we’re chasing watts or riding deep into the unknown, a tidy cockpit with confident control is non-negotiable. The Syncros RR 1.5 Stem checks all the boxes with its fully integrated cable routing and clean, aerodynamic profile. Designed for modern road and endurance bikes, it helps us maintain a sleek front end without compromising on adjustability.

Crafted from lightweight AL7075 alloy, the RR 1.5 features a -6° angle for aggressive positioning and a forged, machined body for optimal stiffness. A removable top plate and hook-type faceplate simplify installation while retaining clean aesthetics. What really wins us over is the ability to swap stem lengths without needing to recut hydraulic lines, saving time and stress. Included spacers and a magnetic top cap cover make it a complete cockpit solution for serious riders.
