How much durability am I sacrificing by going from 725 to Spirit?
I'm looking for my first steel frame, and of course would like something light and stiff. However, I've read a lot about Spirit being too thin and fragile - I already have a CF frame to take care of that . The two bikes I'm looking at have the same geometry and about a ~1.3lb weight difference between them.
Are there any other pros/cons I should be considering?
