AERODYNAMICS We apply aerodynamics where it matters most, and in doing so, we have created our fastest road bike ever – yes, more aerodynamic than the Venge. The front end has been optimized to maximize the advantage. The fork’s steerer tube is positioned further back compared to the front of the frame's head tube, thereby reducing aerodynamic drag. Thanks to the new UCI regulations, for the SL8 we were able to use the narrowest and most aerodynamic seatpost ever made, allowing turbulent air around the legs to flow more easily towards the back of the bike. LIGHTNESS To develop the Tarmac SL8 and ensure the most aerodynamic bike while meeting UCI minimum weight requirements, we drew inspiration from the experience gained with the Aethos. The team created a frame weighing 685 grams, 15% lighter than the Tarmac SL7 and lighter than any other model in the World Tour*. By focusing on maximum lightness in the down tube, seat tube, and rear end of the bike, we applied insights gained from the Aethos project. The frame shapes respond so effectively to stresses, allowing us to reduce material thickness and eliminate the unnecessary. *Except in the case where Kasper Asgreen used our 585-gram Aethos frame during a stage of the Tour. RIDE QUALITY The stiffness-to-weight ratio of the Tarmac SL8 has improved by 33% compared to the SL7. The Tarmac SL8 sets a new standard in handling: it is precise even in the most challenging situations and responds immediately and efficiently to pedal inputs. While the areas that ensure power transfer and steering precision are stiffer than ever, the Tarmac SL8 feels more comfortable, absorbing 6% more vibrations from the road, allowing for cornering with an unmatched sense of agility and balance among race bikes. The new Tarmac SL8 maintains the proven geometry of the SL7 model, offering the same generous 32mm tire clearance, allowing for the use of larger volume tires when needed.
