I do live in the foothills of the Smoky Mountains so there is planty of climbing around that is why the R3 is even on my list. I'm thinking I will go with the R3 I have just yet to see one in person yet and I work for a bike shop thats a cervelo dealer. Tells you how popular the bike is.ericm979 said:What kind of riding do you do? If you don't do a lot of climbing, the soloist could be slightly faster. Me, I mostly care about climbing, so I went with the R3. It's also cheaper, and I liked the ride. Then there is the argument that you should buy a bike to help out your weaknesses rather than accentuating your strengths. Which would invert your preference.
And of course if you are not racing it doesn't make any actual difference. Try riding both and see what you like.
