The Specialized Tarmac SL8 Expert Di2 delivers on every front—speed, agility, and control. Developed after eight generations of race bike innovation, this Tarmac is the fastest yet. Its 685g frame is not only 15% lighter than its predecessor, the SL7, but it’s also the most aerodynamic Tarmac ever made, optimised for clean airflow and reduced drag. The new Speed Sniffer design sharpens the head tube profile for maximum speed gains, while the narrow, aero seat post ensures that air flows efficiently around the rider.
The Tarmac SL8 Expert is equipped with Shimano’s Ultegra Di2 12-speed groupset, offering fast, flawless electronic shifting. Hydraulic disc brakes provide confidence-inspiring stopping power in any condition, ensuring precision at speed and control on technical descents.
Designed using Rider-First Engineering, the Tarmac SL8 adapts to any rider size, delivering consistent stiffness, responsiveness, and comfort. With 32mm tyre clearance, it maintains smoothness on rough roads while retaining the agility needed for fast sprints. Roval C38 carbon wheels provide lightweight speed, and the tubeless-ready setup ensures a hassle-free ride.
