The Tarmac Disc Expert is a premium road bike designed for those who seek a blend of performance and comfort. Ideal for both racing and weekend rides, this bike boasts Specialized's Rider-First Engineered™ technology, ensuring stiffness and compliance in the right areas. The bike's geometry is based on extensive Retül data and professional rider feedback, resulting in a responsive front-end and a short wheelbase for optimal power transfer. For ride quality, the design includes a seatpost that offers compliance in the upper 120mm, dropped seatstays, and a modified seat tube shape. It also provides tire clearance up to 30mm, allowing for decreased rolling resistance, better traction, and enhanced comfort. Disc brakes are a highlight, offering superior braking power, especially in wet conditions. Aerodynamically, the bike has been refined with a new fork shape, aero tubes, and a D-shaped seatpost, making it about 45 seconds faster over 40km compared to similar bikes. 

The build features Shimano Ultegra mechanical shifting, hydraulic disc brakes, and a DT-Swiss R470 wheelset. The frame is crafted from Tarmac SL6, FACT 10r carbon, ensuring a lightweight yet robust structure. This bike truly embodies a race-machine feel with added comfort for longer rides.
