| Front derailleur mount | Braze-on (direct-mount) front derailleur (braze-on tab) |

The Specialized Tarmac SL8 uses an integrated IS42 upper headset for the 28.6 mm steerer, a 27.2 mm class seatpost, a 12x100 front thru-axle and a braze-on front derailleur.
Specialized fits its own aero-shaped post, so the 27.2 mm figure describes the class, not a round Specialized post. The SL8 bottom bracket is a BSA threaded shell, covered on its own page.
