Trek Boone
CX racers. If you want gravel capability, look at Checkpoint or Checkmate instead.
A UCI cyclocross race bike with IsoSpeed on some generations. Tight, muddy, and built to be shouldered — not a Checkpoint with CX tires.

Climbers and riders who want a light Specialized that isn't a full aero race bike. Not an endurance bike.
A lightweight road bike without the Tarmac's aero brief. It climbs and floats; it does not try to be a Tarmac SL7 in a crosswind. The position is still race-adjacent, not Roubaix-tall.
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.
