Hi, I've only been riding a new set of Revelation C19s since January, but would recommend them without hesitation. I've ridden 4 centuries in that time. One century was on particularly horrendous roads that forced the wheels of all of my riding partners to go out of true. My Topos had no such problem. They're extremely plush too, but you'll notice them even more on the hills because they're so light and stiff. Check out the review posted yesterday on pezcyclingnews.com.
