Product Details

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.

About Specialized

Innovate or die.

Founded in California in 1974, Specialized began with a simple promise: serious riders deserve serious gear. Half a century later, the brand still funds its own wind tunnel, builds its own carbon, and tests every bike with the world's best so that you ride your own best.

The first production mountain bike. The first cycling-specific shoes. FACT carbon, the Win Tunnel, S-Works. Specialized has a habit of building the things the rest of cycling ends up copying.
