I will change the current 52 T outer ring to a 50T ramped and pinned 3 Easy Questions: 1. is the modern Specilaized 50 T 110bcc the same as the Sugino 50"T 110? Are both ramped and pinned? ( i know Sugino made some cranks for specialized)

Someone with more bikes than I ride, including those of the modern era, might tell/remind us of the advantages of ramped and pinned chainwheels and the circumstances when those advantages obtain..

I think I push myself and sometimes ride hard, but haven't raced, ridden a triple, riden off-road, or had more than 8 cogs in back. And I use downtube or equal shifters. So, I don't know the advantages of ramps and pins, though I've assembled bikes with them.
