The consequences of this big stack of spacers range from mild (not pretty) to problematic (not considered safe by the bike maker). I personally think a frame is a better fit if it can be ridden without an enormous stack of spacers. If I were ordering a custom bike it would be designed to fit me with no spacers at all.
[To be clear: I realize that some people may not have the flexibility to be on a standard road bike with no headset spacers. I also think that being able to comfortably ride is more important than whether the bike looks better with fewer spacers. But all other things being equal, see above, and try to avoid buying a bike the requires an excessive amount of spacers when other satisfactory options are available.]
The geometry differences between the CAAD 10 and 2020 Supersix make them not identical Cannondale changed the frame geometry in the new Supersix, pushing it slightly towards endurance . On my Synapse I had a low stack height, as I wanted to mimic my 92 Merckx Century. I had the Supersix set up to be similar to the Synapse, so no enormous stack of spacers. They are both more upright than my Merckx but at age 60 that is not a bad thing. It is quite possible to have a 2020 Supersix, be in endurance territory and enjoy a bike that simply handles better. You dont need an enormous stack height to do it. It is the most stable descending bike I have owned in my 45 years of riding.
I also dont think Cannondale would sell a bike like the Supersix that CAN accommodate stack height if it did not intend people to utilize that possibility.
Try it. You will like it!
