ST-R100-AL Stem delivers lightweight integration for Addict RC MY25 cockpit perfection
What Our Gearhead® Experts Are Saying:
"I’m blown away by how well the ST-R100-AL integrates with the Addict RC MY25. It’s incredibly light, and the internal routing keeps my front end super clean. Swapping lengths is easy, and it plays perfectly with Syncros accessories like my head unit mount."
For those of us chasing marginal gains on every ride, the Syncros ST-R100-AL Stem elevates the cockpit of the Addict RC MY25 with race-level integration and refined fit options. We love the clean look, responsive feel, and lightweight construction that keep this stem in step with one of the fastest bikes in the peloton.
Built with an integrated cable routing system, the ST-R100-AL keeps brake and shift lines tucked neatly out of the wind, while a -11° angle helps us stay low and aero. It’s crafted from alloy for a precise blend of strength and lightness, and it’s compatible with Syncros Foil Aero front computer mounts, letting us track performance seamlessly.
