Riders who raced or owned 2021–2023 Tarmacs. A common 'this already fits' bike when shopping SL8 twins.
Aero-and-light Tarmac that replaced the Venge brief. Stiffer cockpit, more integration, and a race position that SL8 later refined rather than reinvented.

Riders shopping the newest Tarmac. Compare stack/reach to SL8 before you assume your size letter carries over.
The next Tarmac generation in the catalog window. Treat it as the race-bike successor to SL8: same family, new tubeset — confirm geometry on the year page rather than assuming SL8 numbers.
