Cervelo R5
Climbers and racers who want Cervelo without S5's deep aero cockpit. Soloist is the value race sibling.
Cervelo's lightweight race bike. It does not try to be an S5. Climbing, precise, and still a low WorldTour stack/reach chart.

Cervelo's lightweight race bike. It does not try to be an S5. Climbing, precise, and still a low WorldTour stack/reach chart.
Racers who want BMC's classic race fit. Roadmachine if you need stack.
BMC's lightweight race bike: steep, precise, and a WorldTour stack/reach reference. Less aero than Teammachine R / Timemachine.
Racers who want the Ineos/Dogma brief. F7 is the more attainable geometry cousin; Dogma X if you want endurance.
The halo Pinarello race bike: asymmetric stays, Italian race fit, and a size run in millimetres (430–595) that does not map 1:1 to S/M/L. It steers like a race bike that wants a skilled rider.
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.
