Specialized Gravel/Road Sizing

Specialized suggests sizes but we'd always recommend test-riding the bike as everyone has different proportions and preferences. We'd say it's especially important if you straddle two sizes.

If you feel little difference between sizes, opting for the smaller generally offers more adaptability down the line. Bikes can quite easily be made to feel bigger, but when trying to shrink a bike that feels too big, your options are more limited.

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. 

Aero where it counts

With a focus on optimizing the leading edge, the Tarmac SL8 is Specialized most aerodynamic bike yet, even outpacing the legendary Venge. The revolutionary nose cone sharpens the head tube’s profile to cut through the air with minimal drag. An aero-optimized seat post ensures clean airflow where it matters most. The result is a bike engineered for ultimate efficiency and speed.

Minimum weight, maximum aero

Weighing in at just 685 grams, the Tarmac SL8 frame is 15% lighter than its predecessor, making it one of the lightest bikes on the World Tour. By applying lessons from the Aethos, Specialized eliminated redundant carbon layers. This balance of lightweight design and aerodynamic performance is race-ready and UCI-compliant.

Goes like hell, rides like heaven

Engineered with 33% better stiffness-to-weight than the SL7, the Tarmac SL8 offers precise handling and explosive power transfer. Shimano Ultegra Di2 components, a Roval Rapide CL II wheelset, and the innovative Roval Rapide Handlebar, makes the SL8 Pro race-ready. Integrated Apple Find My technology in the 4iiii Precision 3+ power meter adds to peace of mind out on rides.
