I like sloping top tubes and I don't mind modern components on a 'traditional' or even genuinely old frame, but that Raleigh looks wrong because of the combination of sloping top tube with long head tube. At least, I think that's the reason. And that chainset is just fugly. But the colour's nice, and it doesn't have unicrown forks, which I personally don't like aesthetically.
Not going to buy it though.
