DESCRIPTION
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. Your legs up for it?
Aerodynamics or lightweight alone don’t win races - speed is what matters. Delivering that speed requires creating an uncompromising combination of aerodynamics, lightweight, stiffness, and compliance. Through race simulations using real world data our Ride Science team knows the Tarmac SL8 is the fastest race bike ever made on the routes that matter - 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, 20 seconds faster over the legendary Tourmalet climb.
- 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 optimized 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. Utilizing 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: Tarmac SL8 took learnings from Aethos to be easily built at the UCI minimum with a full aero set up. The team delivered a mind bending, scale tickling 685 gram frame - 15% lighter than the Tarmac SL7 and lighter than anything on 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 road with a supple feel unique in the high strung world of race bikes. Tarmac’s proven geometry and 32mm tire clearance are identical to the SL7, ensuring easy adaptation and the versatility to run higher volume tires 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 specialize 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 Expert delivers exceptional performance with a full SRAM Rival eTap AXS groupset with power meter, C38 carbon tubeless ready wheelset, and an SL7 stem with Specialized Expert Shallow Drop alloy handlebars makes for an accessible performance-packed bike.

The sizing chart is a great place to start when picking your next bike but everyone will fit a bike a bit differently. Your torso, arm, and leg lengths all play into what size of bike you may need. Plus, there's your own personal preference.
We always recommend swinging by the shop and taking the bike that you're looking for a spin to see how it feels. If you're unable to come by, looking at the geometry of your current bike and comparing it is a good place to start. If you have any further questions, our customer service team is there to help.
