The Specialized Tarmac SL9 Comp SRAM Rival AXS 2027 bicyclefeatured here at Escapa represents Specialized’s ultimate expression of road speed. Its design combines a frame with completely revamped aerodynamics and the balanced handling that characterizes the Tarmac family. The result is a bicycle designed to deliver the fastest possible time to the finish line on real race courses.
This version features the SRAM Rival AXS electronic drivetrain. With a claimed weight of approximately 8 kg, it’s built to accelerate on climbs, maintain speed on the flats, and stay on course with precision during descents.
Speed as the Ultimate Measure
The Tarmac SL9 wasn’t created to stand out solely for its weight or aerodynamics. Specialized has focused its development on a metric more relevant to racing: the actual time it takes to complete a course. To achieve this, the company has combined advanced simulations, aerodynamic testing, and validation in scenarios inspired by real races. This work aims to convert a greater portion of the rider’s power into usable speed, regardless of whether the course includes mountain passes, flat sections, technical turns, or constant changes in pace.
Aerodynamics Developed for Competition
All of the Tarmac SL9’s tubes have been redesigned to improve aerodynamic penetration under the variable conditions of a Carrera. Specialized has applied the knowledge gained from the Tarmac SL8 and its research in the Win Tunnel to reduce drag without adding unnecessary weight.
Narrower Speed Sniffer
The new Speed Sniffer front section is 4 mm thinner, reducing the frontal area by approximately 10%. This evolution allows for better management of airflow around the head tube and fork.
Win Fin System
The Win Fin design directs air around the rear of the bike to reduce turbulence generated in the area of the seat tube and rear wheel.
Flow Fork
The blades of the new fork feature a twisted shape to smooth airflow around the front wheel and reduce aerodynamic drag.
Optimized Aero Seatpost
The seatpost features a deeper, cleaner profile, developed to minimize drag in an area constantly affected by leg movement.
