Specialized Tarmac Sport Disc Road Bike 2020
Specialized's Tarmac Sport Disc Road Bike utilises the latest FACT 9r carbon in its layup to make it lighter than its predecessor. The Rider-First Engineered™ design optimises the material to achieve equal performance benefits no matter which frame size you require. Your position is optimised by the Performance Road Geometry, designed to put you in an aggressive, racy position that maximises power transfer.
Shimano's 105 components balance durability, reliability and performance perfectly, and compact gearing ensures you'll be able to spin up the climbs and reach top speeds on the descents. Hydraulic disc brakes will give you the confidence and control to ride faster even when the conditions are less than ideal. This bike rolls on DT Swiss R470 disc wheels and Specialized Turbo Pro clincher tyres, a great combination that means you'll roll fast and smooth over poor surfaces, with improved traction and protection against punctures.
Features
- 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 and dropped seatstays with aero tubes. The result? A Tarmac that’s approximately 30 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
- Tyre clearance up to 30mm
- Shimano 105 groupset
- DT Swiss R470 Disc wheelset
- Hydraulic disc brakes ensure effective and modulated braking performance
