What is difference between 2010 Specialized Epic S-Works and 2009 Specialized Expert carbon frames?
Is it just the different siwng arm material (S-Works uses Carbon but Expert uses aluminium alloy)?
Are the two swing arms interchangeable?
Anyone have info. on frame and swing arm weight for these two models?
