2020 Specialized Tarmac Expert Ultegra Di2 Disc Road Bike

2020 SPECIALIZED TARMAC EXPERT ULTEGRA DI2 DISC ROAD BIKE
Specialized's Tarmac Expert Ultegra Di2 Disc Road Bike has sleek and understated aesthetics and the performance to match. The FACT 10r carbon frame and redesigned fork keep weight low while a Rider-First Engineered design means that each frame size has a unique layup to benefit from equal ride characteristics. Small but significant changes in the fork and tube shapes, together with a D-shaped seatpost and seat tube, bring an aerodynamic advantage. This is a bike engineered for fast riding; it's stiff for efficient power transfer, with a Performance Road Geometry that includes a responsive front end and a short wheelbase. Dropped seatstays and flex in the upper portion of the seatpost ensure the ride is never too harsh with the added compliance taking the sting out of the roughest roads.

This Tarmac has been built up with Shimano's second-tier electronic groupset - Ultegra Di2 - which ensures every shift is fast, smooth and precise, and mid-compact gearing provides a good range of gears for climbing, sprinting and descending. Rolling on Roval C 38 Disc wheels and S-Works Turbo 26mm tyres, acceleration is excellent and resistance low while the 38mm rim depth blends aerodynamics and stability.

FEATURES :
• Advanced aerospace composite optimisation software revolutionises the construction and layup of the latest FACT 10r 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 40 kilometres
• 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
• New seat tube shape
• Tyre clearance up to 30mm
• Shimano Ultegra Di2 electronic shifting
• Carbon fibre Roval C38 wheelset is fast-rolling and lightweight
• Hydraulic disc brakes ensure effective and modulated braking performance
