Hi @Mike_Rowe1, thanks for responding. Yes, I looked at those and some others as well, and that’s how I ended up buying the two setups. Basically, for climbing I bought the lightest frame and lightest wheels; and for aero it was fastest frame and fastest wheels (all given what I could afford with available drops). But I couldn’t find anything as comprehensive about the different combinations of frames/wheels (and in particular the ones I have). I know it’s a fine-grain question that’s not likely of general interest.
