AERO IN EVERYTHING: Aerodynamics are key; and the Tarmac SL8 is optimised for it in every detail. The new nose cone; called the Speed Sniffer; sharpens the leading edge by moving the steer tube back; resulting in the most aerodynamic road bike Specialized has ever made. Utilising new UCI rules; the Tarmac SL8 also features the narrowest; most aero seat post ever designed by Specialized; ensuring smoother airflow around the legs for maximum speed. MINIMUM WEIGHT; MAXIMUM AERO: By incorporating lessons from the Aethos; the Tarmac SL8 is built to hit the UCI weight minimum with a full aero setup; boasting a frame that weighs just 685 grams; 15% lighter than the SL7. This lighter weight doesn’t compromise aerodynamics; making the SL8 lighter than any bike on the World Tour. The frame design efficiently carries loads; eliminating the need for additional carbon stiffness layers. GOES LIKE HELL; RIDES LIKE HEAVEN: With a 33% improvement in stiffness-to-weight over the SL7; the Tarmac SL8 offers next-level handling; responsiveness; and comfort. It’s stiffer at the pedals; more precise at the bars; and provides a compliant ride in the saddle; setting a new benchmark for race bike comfort. The SL8 delivers 6% more compliance; gliding over rough roads with a unique suppleness. The proven geometry and 32mm tyre clearance ensure versatility and ease of adaptation. BEYOND GENDER: Specialized believes that gender doesn’t dictate the best bike for a rider. The Tarmac SL8 is designed for all cyclists; offering the same unparalleled ride quality and performance to everyone. The Tarmac SL8 Expert Di2 features a full Ultegra Di2 groupset; C38 carbon tubeless-ready wheelset; and an SL7 stem with Specialized Expert Shallow Drop alloy handlebars; making it an accessible; performance-packed option for serious cyclists.
