Specialized S-Works Tarmac Stem

Performance & Use Case
The Specialized S-Works Tarmac Stem is purpose-designed to complement the Specialized Tarmac platform. The -6° variant suits a more upright, endurance position; the -12° variant puts the rider in an aggressive racing position. The integrated face-plate slot accepts a computer mount without adding a third-party clamp to the cockpit – keeping the front end aerodynamically clean.

Construction & Materials
Manufacturer-claimed weight 155g for the 100mm size. Black finish matches Tarmac aesthetics. Computer mount slot integrated into the face-plate.

Compatibility & Variants
Designed for the Tarmac integrated cockpit. Handlebar clamp diameter 31.8mm. Available in two rise angles (-6° and -12°) across lengths from 70mm to 140mm in 10mm increments. Select the length and angle that match your bike fit and ride position.
