Racers and fast club riders who want the modern Tarmac. If you came off an SL7, check that the stack/reach still matches your size.
The current Specialized race bike: lighter than SL7, still aero, and famously 'it just disappears' if the fit is right. Size by stack/reach — the 54/56 split is where a lot of riders hop.
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.
Racers who want a climbing Orbea. Orca Aero is the wind-cheating sibling.
Orbea's lightweight race bike, OMX carbon on high kits, and a fit that is race-low without S5 drama. OMX vs OMR changes weight more than geometry.
