I just received the Silvio S30 frame set last week and am figuring out what components to put on it. Just for some perspective, in 2009, I bought the Silvio 1.0 frame set for $2920 while the S30 frame set was $2450--good deal!
At first, I was perfectly happy with the 1.0, but after a while, I wanted to make some improvements:
1) lighter weight, especially the front end
2) smoother/rounder shaped frame, mostly for aesthetics, but stiffer for more efficient power transfer would be good
3) lower handlebar position for more comfort and over-the-handlebars visibility (I'm 5' 5" and probably shrinking)
4) carbon fiber seat with Ventisit pad
5) more reclined seat back position
6) room for wider tires, at least 28mm with wider rims
7) easier to remove and replace front wheel--rear derailleur is loose on 1.0
Somehow, Cruzbike read my mind and incorporated all of my wishes, and more, into the S30. It's subjective, but I really like the S30's hydroformed frame and the new graphics. I was actually going to cut off the 1.0 metal seat and install a carbon fiber seat I had, but the planets aligned and I ended up buying the S30. I'll be installing a Shimano 105 11-speed compact double, and I just found out the new 105 brakes accommodate wider tires. I'm still working on whether or not an 11-speed XT rear cassette and derailleur will work with the 105 11-speed brifter since I want an 11-36 or 11-40 cassette.
So, as others have said, it all depends on what you want, and I know the price difference is probably substantial, but in the long run, you could be better off with the S30 IF it has what you want. In my case, for my needs, the S30 seems to fit and I can't wait to get it rolling. BTW, I'm planning on keeping the 1.0 as well.
