i have a 14lb s-works aethos, 12 speed da/di2, disc brakes of course, and the two big compromises it brings are aerodynamics (relatively shallow wheel profiles, round tubes) and cost. It’s really the only bike i ride, and I ride it a lot, so the latter isn’t too much of a concern. I do sometimes wonder how much faster an extra pound of wheels and frame in the interest of aero would make me, and now much would the ride quality suffer from the bigger profiles in various locations.
