>>1681255You right that campy makes shifter hoods with the word "ergo" in their brand name.
It's also true that "ergo" is shorthand for "ergonomic" which, in general, means something like "comfortable".
All shifter hoods are ergonomic in the sense that they are more or less comfortable for people. However, since different people have different sized and shaped hands (or no hands), then one shifter hood design might afford comfort to one person while another shifter hood design might afford comfort someone else.
Campy "ergo" hoods might be uncomfortable for some people. Having the word "ergo" in your brand name does not have any effect on whether a particular hood design is comfortable or not.
