I'm old (62) and I'm old school. I ride an old school bike ('84 Peugeot) that I bought new, still use dt friction shifters, wear DETTO cycling shoes and a checker board PEUGEOT jersey and use toe cages and rat trap pedais and a PROFILE aero bar. THAT, mes amis, is old school. If you use Velo Retro's definition of old school, it's any thing pre '85, i.e. no carbon, click shift, brifters or clipless pedals.
