I have a Roubaix with the "Future Shock" front fork and the Zertz in the seat post, plus 28mm tires. It is a huge difference over my previous Roubaix without the future shock. There is one particular bridge...
I have one of these two and I highly recommend it. There's some bridges on the MUPs I use here which are made of wooden planks, and it's pretty remarkable how much smoother it is to ride on them with this bike. Overall, it's a very comfortable bike, except for the saddle; I really need to get another one as their stock 143mm "Phenom" doesn't seem to fit me well and makes me sore after ~10 miles.
I have to say, I think the higher-end bike manufacturers and their affiliated shops are missing out on an opportunity here: they should be automatically, as part of the new-bike-buying experience, be helping you find a saddle that fits you well and putting that on your new bike, instead of including some default saddle that seems to fit no one well and sticking you with that, forcing you to buy another saddle and eBay the old one. They could go farther with other parts on the bike too: handlebars, stem, etc.
