Product Description
2026 TARMAC SL8 PRO – SHIMANO ULTEGRA Di2
WorldTour Performance. Ready to Race Out of the Box.
Nothing is faster than the Tarmac SL8 Pro. By blending the ultra-low weight of the Aethos with the aero efficiency of the Venge, the SL8 is the ultimate race machine. Featuring the all-new Roval Rapide CL III carbon wheels and a full Shimano Ultegra Di2 groupset with an integrated power meter, this build delivers uncompromising speed for the most demanding riders.
Innovation at the Leading Edge
- The Speed Sniffer: The SL8's revolutionary nose cone moves the steerer tube rearward to sharpen the head tube profile, significantly reducing drag compared to the SL7.
- Minimum Weight, Maximum Aero: Utilizing advanced FACT 10r carbon, the frame weighs a mere 685g—meeting UCI minimums with a full aero setup while offering a 33% improvement in stiffness-to-weight.
- Roval Rapide Integrated Cockpit: A seamless, one-piece carbon handlebar and stem system that cuts through the wind and saves precious watts.
- Shimano Ultegra Di2 with Power Meter: Lightning-fast 12-speed electronic shifting paired with an integrated 4iiii Precision 3+ Power Meter for professional data tracking.
- Roval Rapide CL III Wheels: Aerodynamically optimized carbon wheels with DT350 hubs, delivering stability in crosswinds and explosive acceleration.
