Still unsure about the comfort /Sportive geo. Personally I went for a full-on road frame and cut the steerer slightly longer so I can lower the stem height as I prefer- logic being that if I bought a Sportive, I’d end up getting a mentalist road bike in the end anyway. Unless you want a do-it-all long distance, all weather machine with rack and mudguard mounts then go for a proper road frame.
I use SPDs on my road bike- means only 1 pair of shoes across 3 bikes and easier to unclip at traffic lights.
