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.
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 a boutique aero-light bike. O2 VAM is the climbing sibling; LS is gravel.
Factor's aero-all-rounder: light enough to climb, aero enough to race, and a stiff, precise race bike that reviewers keep measuring against the Tarmac SL8.
