Racers and fit club riders who want a low stack without full aero integration. If the Aeroad cockpit feels like too much, this is the sibling.
Canyon's lightweight race bike: snappy, precise, and less of a wind-cheater than the Aeroad. It rewards a committed position and calm hands in corners rather than a slammed aero tuck.
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 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.
