Tarmac SL8 Pro - Shimano Ultegra Di2
Made to race
Nothing is faster than the Tarmac SL8. 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, made even faster with the aero-optimised performance of the all-new Roval Rapide CL III wheels.
Best for: Road racing, fast group rides and performance-focused training.

Key highlights
15% lighter than the Tarmac SL7 with a 33% improvement in stiffness-to-weight, so more of every watt goes into forward motion.
A reshaped nose cone and narrow, UCI-legal aero seatpost cut drag at the leading edge, making the SL8 more aerodynamic than the Venge.
A full Ultegra R8100-series Di2 groupset paired with a 4iiii Precision 3+ power meter (with Apple Find My support) means it's ready to race out of the box.
Tubeless-ready carbon wheels built specifically around the SL8's aero-first philosophy.
