NBD! rolling hills 10 mile loop around Black Mt. before work. Bike is smooth and responsive even with my lack of morning energy. Bottom bracket box on this is massive compared to 1 gen old Pinarello. Uses new T47 threaded shell, one side of external and one is internal allowing for more CF in that zone for stiffness. Geo is nearly identical to the Pinarello GanS, the seat tube angle is like 0.3* steeper. But this bike can clear much larger tires 26c vs Soloist claims 34c. And disc brakes are nice to have to the downhill fun.
still have to dial in fit before getting cables shortened. Maybe try one more spacer removed while riding one the trainer this week. Compare power numbers too.
