The Wilier Stemma S2 features a four-bolt handlebar clamp design that is stiff, practical and secure, giving you confidence in the cockpit whether you are sprinting, climbing or descending.
At its core, the stem is designed to cleanly conceal cables into the headset and frame, with up to three cables including rear brake, shifter or electronic drivetrain components integrated discreetly for a clean, modern aesthetic. The Stemma S2 routes cables seamlessly into the frame without compromising on stiffness or adjustability.

Designed and built to complement the wider Wilier cockpit range, the Stemma S2 delivers the integrated, purposeful look that defines the Wilier Triestina aesthetic, without asking you to compromise on quality or practicality.
