Orbea Orca Aero
2027 · 700c wheels · 7 sizes
Orbea's carbon aero race bike, redesigned for 2027 with room for 37 mm tyres. The numbers are from Orbea's geometry table for the Orca Aero, and the stock parts are from the M21e LTD build. Orbea's figures are rounded, so its horizontal top tube comes out 1 to 2 mm shorter than you would get by working it out from reach, stack and seat angle.
