Cervelo R5: Stack: 548mm, plus 10mm top cap, 10mm spacer, 100mm -6 stem. The frame reach is 380mm. HT angle is 73
Orbea Terra: Stack: 560mm, plus 15mm top cap, 0mm spacer, 100mm -12 stem. The frame reach is 378mm. HT angle is 71

I'm using the same bars (77mm reach), saddle, saddle height, and saddle setback (laser measured) on both bikes.

Based on stem comparison tools (and mental math) the two bike should be, near-as-makes-no-difference, the same. Yet, my Terra has 1.5cm less saddle-to-bar drop and 1cm short reach (saddle nose to hoods)...anyone know what's going on? I've been struggling to get comfortable on the Terra since the day I got it (back in January), and I'm to the point that I'm ready to replace it.
