The combination of Specialized's advanced FACT 12r carbon frameset, Shimano's top-end Dura-Ace Di2 groupset and aerodynamic Roval CLX 50 wheels, makes the S-Works Tarmac SL6 Di2 Women's Road Bike an outstanding race bike.

Stiff and compliant, this bike offers snappy acceleration and excellent power transfer thanks to the carbon fibre S-Works crankset, that includes a dual-sided power meter. With a frame weight below 800 grams this bike is perfect for smashing your hill climb personal bests, and Rider-First Engineered™ technology ensures the performance benefits are the same across all frame sizes.

Specialized S-Works Tarmac SL6 Di2 Womens Road Bike 2018

Every element of the S-Works Tarmac SL6 Di2 Womens Road Bike has been designed to perform at the highest level. Specialized's new FACT 12r carbon utilises advanced aerospace composite optimisation software to completely revolutionise the construction and layup. The new design has resulted in a 20% weight reduction, resulting in a frame weight of below 800 grams.

Specialized's Rider-First Engineered™ technology has also been improved for added stiffness and compliance in all the right places. Taking numerous Retül data points and feedback from professional riders, a geometry has been developed that is optimised for performance on the road. The stiff and responsive front-end combined with a short wheelbase results in instant responses and optimal power transfer so you can react at lightning speed to attacks, and accelerate with snappy intensity.

Despite all its performance features, this bike is still comfortable to ride for longer durations, effectively smoothing out the roads. The upper portion on the S-Works FACT carbon seatpost has had some extra compliance built in, and dropped seatstays and an updated seat tube shape further contribute to ride quality. With clearance for tyres up to 30mm (28mm for the Turbo Cotton tyre), you can reap the benefits of riding on lower tyre pressures, notably, decreased rolling resistance and increased traction, as well as enhanced comfort.

Not purely a lightweight climbing bike, aerodynamics have also been well considered, without taking away from the hallmarks of the Tarmac design. A new fork shape, dropped seatstays with aero shaped tubing and a d-shaped seatpost and seat tube result in a bike 45 seconds faster over 40km than others in its category.

Shimano's new electronic Dura-Ace Di2 groupset complements this frameset perfectly. Light and ergonomically designed, shifting is precise and fast, and at just the touch of a button. The direct mount brakes offer powerful braking, giving you the confidence to take technical corners and steep descents at speed. There's no need to invest in a separate power meter to enhance your training, the Specialized S-Works FACT Carbon includes a dual-sided power meter as standard.

The Roval CLX wheelset is lightweight, aerodynamic and incredibly stiff. The rigid carbon construction includes an Aero hub that uses high-quality CeramicSpeed bearings for reduced rolling resistance and friction. The wheels are finished off with Specialized's Turbo Cotton 26c tyres; one of the fastest and most efficient clinchers available. This bike has been specced specifically for female riders, with frame size-specific handlebars and crank arm length and a women's specific saddle.


  • Featuring Rider-First Engineered™ design that ensures every frame size has the same legendary climbing responsiveness and descending prowess you'd expect from a top-performance race bike. The S-Works FACT 12r frameset is Specialized's highest quality carbon frame, offering the ideal blend of light overall weight and targeted stiffness
  • S-Works-specific FACT full carbon fork with tapered construction provides incredible front end stiffness and steering response for instantaneous accelerations and high-speed descents
  • A 52/36T S-Works carbon fibre crankset offers the ultimate in power transfer, with a chainring grouping that's equally suited to big alpine climbs as it is to throwing down the gauntlet on the flats
  • Includes the S-Works Power Cranks dual-sided power meter
