Why choose the Tarmac SL8 Pro: main features
Superior aerodynamic performance
The new Tarmac SL8 is more aerodynamic even than the legendary Venge. The advanced design includes:
Setback fork steerer to reduce air resistance.
New ultra-thin seatpost thanks to updated UCI rules.
Maximum airflow efficiency, even in the most turbulent areas like the legs.
Record-breaking lightness
Inspired by the Aethos, the SL8 boasts a frame of only 685 grams, 15% lighter than the SL7 and lighter than any other World Tour bike*.
The Specialized team reduced material in less stressed areas, optimizing weight and stiffness for a responsive and lightweight bike without sacrificing aerodynamic performance.
(*Except for the 585g Aethos used by Kasper Asgreen at the Tour.)
Unrivaled ride quality
The new Tarmac SL8 has a stiffness-to-weight ratio 33% higher than the SL7.
Responsive and precise in the most demanding situations.
Better vibration absorption (+6%), for a smoother and more comfortable ride.
Space for tires up to 32 mm for versatility and performance even on less perfect roads.
Designed for every cyclist
Specialized goes beyond traditional gender differences. The Tarmac SL8 is designed to fit every cyclist, man or woman, offering top performance tailored to every body.

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