A couple years ago I had a thorough fitting (results attached) on my 58cm Roubaix which included changing the stem to a 90mm -17° from the default 100mm stem that came on the bike. The bike got smashed last September and I didn’t have the final measurements, but since the fitting then the only thing changed was removing a small spacer, at that point it was perfect.
I’ve tried to replace it with a “large” defy with the 90mm stem but am finding the hoods are a few cm out of ideal reach. I had to take some months off from an injury but I suspect even given some lost flexibility/core strength that should return, it’s still a bit of a stretch. Comparing the geometries it’s clear the defy is larger than the roubaix so I might’ve been better suited for the M/L, and **it has me wondering if I should be shopping 56cm bikes rather than assuming I need another 58 with the -10mm stem? Or will that leave me with too much seat tube?
I’m 6-2 with a 32” inseam, middle aged without a yoga-master’s flexibility. I’m struggling a bit to translate my fit report’s “reach” and saddle height not directly translating to mfr geometry data using different measurement points such as the seat tube not including the saddle and seatpost.
A local shop has a M/L defy as well as a 56cm Domane I’m considering, and wonder if the Domane being -9mm reach from the default Roubaix reach measurement wouldn’t be a pretty close fit - though I know the other numbers factor in and are important. Any advice from those used to “reading” these geometry numbers?
