The Domane is a well made bike with a lot of longevity... like your Roubaix. I've had my S5 model with Shimano 105 since the summer of '16. Last November my Domane had a major overhaul on parts... replaced cassette, chain, cabling, rear wheel, new 28mm tires from 25mm tires and major cleaning of frame, etc, which cost around $1K at LBS. It was either that or dish out $3,800 on a new Domane with carbon frame. I chose to get another 8-9 years out of my old 2017 Domane instead.
