Tarmac SL8 Pro Force eTap AXS Road Bike 2025
Nothing is faster than the Tarmac SL8, thanks to a combination of aerodynamics, lightweight, and ride quality previously thought impossible. After eight generations and over two decades of development, it’s more than the fastest Tarmac ever. It’s the world’s fastest race bike. Are your legs up for it?
Aero in Everything: We’re putting aero where it matters—the leading edge, not just where it looks good. In the process, we’ve created our most aerodynamic road bike ever. Yes, it’s more aero than the Venge. Clean air is optimised for maximum advantage with the Tarmac’s new nose cone, the Speed Sniffer. By moving the steer tube back, the tube that determines head tube width, the leading edge of the head tube can be much sharper, delivering a much lower drag shape. Utilising new UCI rules, the Tarmac SL8 has the narrowest, most aero seat post we’ve ever made, ensuring fast-moving, dirty air around the legs can flow back more cleanly. Doesn’t victory smell sweet?
Minimum Weight, Maximum Aero: The Tarmac SL8 took learnings from Aethos to be easily built at the UCI minimum with a full aero setup. The team delivered a mind-bending, scale-tickling 685-gram frame, 15% lighter than the Tarmac SL7 and lighter than anything else on the World Tour. With the ability to make lightweight a top priority in the down tube, seat tube, and rear of the bike, lessons from Aethos were applied. The frame’s shape carries load so efficiently that extra carbon stiffness layers become redundant. Unless, of course, you count the time Kasper Asgreen raced our 585-gram Aethos frame during a Tour stage.
Goes Like Hell, Rides Like Heaven: With massive gains in stiffness-to-weight, an improvement of 33% over the SL7, the Tarmac SL8 takes legendary handling, aggressive responsiveness, and World Championship-proven geometry to the next level. The bike is stiffer at the pedals, more precise at the bars, and combines it with a compliant ride in the saddle that sets a new benchmark for race bike comfort. Thanks to our Rider-First Engineering, every rider, regardless of size, gets the same unprecedented ride quality and handling. In the saddle, the Tarmac SL8 delivers 6% more compliance, floating over rough roads with a supple feel unique in the high-strung world of race bikes. Tarmac’s proven geometry and 32mm tyre clearance are identical to the SL7, ensuring easy adaptation and the versatility to run higher volume tyres when needed.
Beyond Gender: There can be more difference between two male cyclists than between a male and female. Gender alone doesn’t provide nearly enough data to specialise, and that means creating male or female bikes is arbitrary and outdated. Every rider can get the next level advantage of Tarmac SL8. It’s time to go Beyond Gender.
The Tarmac SL8 Pro delivers exceptional performance with a full SRAM Force eTap AXS groupset with power meter, Roval Rapide CL II tubeless-ready wheelset, and a Roval Rapide handlebar with an SL7 stem. You’re ready to race out of the box.
