I'm looking for an aero bike that meets two conditions: a carbon frame and a Shimano 105 mechanical groupset
but there's always a thing or two I don't like about the design or the color, so I can't decide.
Besides Trek, Giant and Merida, are there other brands worth looking at? (I'd prefer a brand with good domestic after-sales service, but it's not a requirement)
I looked at Canyon and Cervélo too but they're too expensive..
