Specialized Tarmac SL8 Pro Shimano Ultegra Di2 – The fastest road racing bike in the world

The Specialized Tarmac SL8 Pro Ultegra Di2 represents the ultimate evolution of the modern racing bike: more aerodynamic, lighter, and more responsive than any previous Tarmac. After eight generations and over twenty years of research, the SL8 sets new performance standards: it is simply the fastest road bike ever developed by Specialized.

Thanks to the perfect combination of advanced aerodynamics, optimized stiffness, reduced weight, and superior ride quality, the Tarmac SL8 is designed to deliver real speed on any course:

  • 16.6 seconds faster over 40 km on flat terrain

  • 128 seconds gained on the Milano–Sanremo route

  • 20 seconds faster on the Tourmalet climb

If you're looking for a race bike that turns every watt into pure speed, the Tarmac SL8 is ready to take you beyond your limits.


Aerodynamics – The most advanced ever seen on a Tarmac

Specialized focused aerodynamics only where it really matters, achieving the most aerodynamic road bike in its history — even faster than the legendary Venge.

  • New optimized front area to drastically reduce air resistance.

  • Fork steerer tube set back relative to the head tube for cleaner airflow.

  • Narrower and more aerodynamic seatpost ever produced by Specialized, made possible by new UCI regulations.

Result: the turbulent air produced by leg movements flows away more efficiently, ensuring better aerodynamic penetration.


Lightness – Frame weighing only 685 grams

To create such a light and aerodynamic frame, Specialized applied technologies developed with the Aethos project.

  • 15% lighter than the Tarmac SL7

  • Lighter than any World Tour bike (except the 585 g Aethos used by Asgreen in a Tour stage)

The FACT 10r frame responds so efficiently to stresses that it allows a reduction in thicknesses, eliminating all unnecessary material.


Ride quality – Stiffness, agility, and comfort at the highest levels

The Tarmac SL8 features a stiffness-to-weight ratio 33% higher than the SL7, with:

  • Greater precision and responsiveness in technical situations

  • Direct and instantaneous power transfer

  • Increased comfort of 6% thanks to the ability to filter vibrations

It retains the proven SL7 geometry, with space for tires up to 32 mm, perfect for those seeking speed and versatility.


Total inclusivity – Beyond any gender difference

Specialized designs based on the real needs of cyclists, not gender.
Men and women can enjoy the same advantages of the Tarmac SL8: a race bike perfectly balanced for every body type.


Pro Build – Race Ready

The Tarmac SL8 Pro is equipped with:

  • Shimano Ultegra 8100 Di2 group with powermeter

  • Roval Rapide CL II tubeless ready wheels

  • Integrated Roval Rapide cockpit

A race-ready setup immediately ready to ride.

Find the Size

A Complete Guide to Bike Sizes

Foreword: Not all bike sizes are the same

Each type of bike has a specific frame and often uses a different size scale. For example, a road bike with a 54cm frame might be considered a medium size by one brand, but a large by another.


Bicycle adjustment margins

Some types of bikes, like gravel bikes, offer a wide range of adjustments, adapting to different body types. Other models, however, have limitations in this regard. This is an important aspect to consider.


How to use size charts

We've created a simple guide to help you find the right bike size:

  1. Check out our size charts for each bike type.
  2. Learn more with specific tips to help you make the right choice.

Size Charts: Find Your Perfect Bike

Gravel and road bikes

Sizes are based on the length of the top tube (in cm), which determines the reach of the bike.

Cut Recommended height Horizontal tube length
XS Up to 157 cm 48-50 cm
S 157-167 cm 50-53 cm
M 168-178 cm 53-56 cm
THE 178-185 cm 56-58 cm
XL Over 185cm 58-62 cm

For gravel, measurements may vary slightly due to different geometries, but remain similar.

Mountain bike

MTBs are measured in inches, based on the seat tube.

Cut Recommended height Size (in inches)
XS Up to 157 cm 14"-16"
S 157-167 cm 15"-17"
M 168-178 cm 16"-19"
THE 178-185 cm 18"-20"
XL Over 185cm 20"-23"

Sizes also vary depending on the type of MTB: full-suspension , hardtail or fat bike .

Children's bikes

The size depends on the size of the wheels, often associated with age:

Age Wheel Size
1-3 years 12"
2-4 years 14"
4-6 years 16"
5-8 years 20"
8-10 years 24"
Over 10 years 26"/27.5"

What to do with half measures?

If you are between two sizes:

  • Comfort : Choose the larger size.
  • Performance : Go for the smaller size.

Final tips for choosing

  1. Consult the manufacturer's instructions : Always check the brand's guidelines.
  2. Ask an expert : a specialized workshop can help you choose based on your height, ideal reach and goals.
  3. Test the bike : If possible, test the model you intend to purchase.
