I'm moderately familiar of the steel framed bikes of road racing in the eighties and early nineties, but I recently realised that I have a gap in my knowledge from the early nineties to the modern carbon frame that dominates the Peloton. I know this is modern-vintage, but when did steel change to carbon and was there Alu/Ti in between? I can't remember seeing a single bike from this transition era. Does anyone have any info or resources for me to understand more?

Thanks a ton!
