Specialized Tarmac Comp Ultegra Disc Road Bike 2020
Specialized's Tarmac Comp Ultegra Disc Road Bike offers true all-round performance. It's light, stiff and compliant, excelling on the climbs and the open windy flats alike. Faster than its SL5 predecessor, the latest 9r carbon has a Rider-First Engineered™ design to ensure the ride characteristics are equal across the range of sizes, while a Performance Road Geometry puts you in an aggressive yet comfortable position. Aero details include a D-shaped seatpost and seat tube and a redesigned fork shape. The seatpost also has flex built-in and, together with dropped seatstays, impacts from the road are effectively soaked up to reduce fatigue and make every ride more enjoyable.
Shimano's Ultegra components feature trickle-down technology from the flagship Dura-Ace range so you get all the technology with just a slight weight penalty. Shifting is smooth and precise, with mid-compact gearing offering enough range for the climbs and fast descents alike. DT Swiss R470 disc wheels and Specialized Turbo Pro 26mm tyres keep the weight down, while grip and puncture protection is excellent.
- Advanced aerospace composite optimisation software revolutionises the construction and layup of the latest FACT 9r carbon
- Rider-First Engineered™ design - every frame gets a unique layup schedule with different ply arrangements, orientations, quantities of material in specific areas, and sometimes, even exclusive thicknesses and types of carbon itself
- Aero features without any cost to weight. A new fork shape, dropped seatstays with aero tubes, and a D-shaped seatpost and seat tube. The result? A Tarmac that’s approximately 45 seconds faster over 40km
- The updated Performance Road Geometry is based on countless Retül data points and professional rider input. Combines a responsive front-end and short wheelbase, which deliver an instantaneous response and optimal power transfer
- The seatpost has flex built-into the upper 120mm where clamping doesn't happen
- Dropped seatstays add compliance
- Tyre clearance up to 30mm
- Shimano Ultegra drivetrain
- DT Swiss R470 Disc wheelset
- Hydraulic disc brakes ensure effective and modulated braking performance
