Hello all, I was trying to make the same decision myself over the past few weeks, and ended up ordering the 2018 Elite Roubaix in the matte black. I live in US, ordered the bike on Saturday and it is due in this Friday. I have a 2017 Diverge DSW, but wanted an upgrade, and the hydro brakes were a must. I have mech brakes on my Diverge, Hydro on my MTB and can tell a huge difference. Was looking into the 2017 Comp Roubaix, but they arent discounting them at all around me yet. Was going with the comp until I saw the 18 Elite had the brakes I wanted. When comparing the 18 comp and elite, I also could not justify the price difference. Plus the 18 comp colors are not so good looking to me. I love the yellow/orange 17 comp, but that one is no where to be found, and unable to order anymore through specialized.
