At Mackay Cycles, we recommend the Tarmac SL8 Pro for riders chasing a fast, responsive, and race-ready bike with the reliability and performance of Shimano Ultegra Di2.
Built for Real-World Speed
The Tarmac SL8 is engineered to be faster across real-world riding conditions. By combining aerodynamics, stiffness, and compliance, it delivers measurable gains where it matters most—on climbs, flats, and race scenarios.
Aero Where It Counts
With a refined front-end design and optimised airflow, the SL8 reduces drag at the leading edge. From the head tube to the seatpost, every detail contributes to improved efficiency at race pace.
Lightweight Carbon Performance
The FACT 10r carbon frame offers an ideal blend of low weight, stiffness, and durability. It climbs efficiently while maintaining the aerodynamic advantages of the Tarmac platform.
Fast, Precise, and Comfortable
Improved stiffness-to-weight ensures strong power transfer, while added compliance provides a smoother ride over rough roads. The result is a bike that feels quick, controlled, and comfortable for long rides or race efforts.
Shimano Ultegra Di2 with Power Meter
Equipped with Shimano Ultegra Di2 electronic shifting and a 4iiii power meter, this build delivers precise shifting, reliable braking, and advanced performance tracking for training and racing.
