I currently have a 2006 Specialized SWorks Roubaix which I built up with full Ultegra (inc wheels) a few years back. I have the chance to buy (upgrade?) to a nearly new (100 miles) 2014 Scott CR1 Premium. Both bikes are similar in weight and geometry, Scott has di2 which is appealing. Two main questions I need help on are;
- does carbon have a specific lifespan (current bike 10 years old now)?
- have carbon frames moved on significantly in terms of performance? (2006 vs 2013)
