This forum is buggy. Lost my response 3 times during auto save. So this will be short. Only fair comparisons are what Dave has done. Actual side by side comparisons of specific bikes. Even then the findings are biased by the testers. ckc 189, only you know your intentions for this bike. Restore the bike or upgrade till there is no where else to go with it. A 2008 bike will have limitations at some point.

My experience is that in the last few years Shimano mechanical road groupsets at 105 and above provide similarly flawless shift performance. It doesn’t need to get any better. The biggest differences between them come down to the materials used and weight savings of the higher end groupsets. But we are talking ounces for the drivetrain and brifters only.

Hope this helps.
