The Tarmac Expert is a purpose-built race machine, equipped with the expert performance of the Shimano Ultegra 11-speed drivetrain. When you are travelling to Adelaide to ride, why would you ride any other rental bike?
The FACT 10r carbon frame featuring Specialized's Rider-First Engineered™ design ensures uniform performance metrics across the entire size run.
Rider-First Engineered™ is a totally new way to approach bicycle development that grew out of our partnership with the leaders in Formula 1 development, McLaren. Rider-First Engineered™ begins and ends with the Rider; each of the seven frame sizes was developed independently, based exclusively on the real-world stresses introduced by the corresponding rider.

Strategically designed head tube on SL4 frames tapers from 1-1/8” at the top to 1-3/8” at the crown and facilitates massive top and down tube junctions.
