Specialized S-Works Tarmac SL8 – Dura-Ace Di2 – Custom 58cm
Nothing is faster than the Tarmac SL8 thanks to a combination of aerodynamics, lightweight, and ride quality previously thought impossible.
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.
- AERO IN EVERYTHING: Putting aero where it matters – the leading edge – not just where it looks good. In the process Specialized created the most aerodynamic road bike ever. Yes, it’s more aero than the Venge.
- 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 Specialized team delivered a mind bending, 685 gram frame – 15% lighter than the Tarmac SL7 and lighter than anything on else on the World Tour.
- 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.
- S-Works Tarmac SL8 is spec’d with only the best components. A full Shimano Dura-Ace 9200 series Di2 groupset with dual-sided power meter, and a Roval Rapide CLX II tubeless-ready wheelset is the perfect complement to the world’s fastest frame. This S-Works Tarmac SL8 model ships with a Roval Rapide cockpit to save weight and for the fastest possible leading edge.
- ‘Apple Find My’ technology is now integrated in all SW & Pro 4iiii power meters. Riders can now enjoy the peace of mind that comes with knowing the exact location of their bikes.
