A friend on another site got a Caledonia and really like it, and I would love one ..... Not as racy as the R series, and not as pricey, and fits tires up to 34 mm so it can pretty much do everything. I have never ridden one but the guy on the other site--he is one of those crazy old guys who rides crazy amounts even though he is past 70--he has a lot of experience and could buy whatever he wanted ... that is what he got.
Specialized? I want an S-Works Aethos ...

I have no use for one but I love light bicycles. Way too racy and way too expensive.
I really don't know much ... but with the added info the much smarter people where will be able to help.
