Well let me chime in. Today I took my modern carbon fiber Scott CR1 Pro out for a century ride. The exact same route I did last week on my steel mid 90s Giordana Superleggero. Last week I finished with my usual foot pain but was otherwise totally fresh and ready for more miles. This despite not getting enough water and carbs in me during the ride. But this week I hydrated better and got a lot more carbs in me during the ride. But the Scott beat the crap out of me physically. By mile 75 I was very sore all over, wore out, and wanted to quit. The final miles sucked. That is precisely way I prefer vintage.
