I'm not very familiar with all the different component groups available and wondered if there's a chart that ranks their quality (or price).
So I'd know that Shimano 105 is the same level as SRAM Apex (just and example, I don't know). So I can get it in my head a general idea of where these component sets stack up against each other so when I look at bikes I'll know (generally) the quality of the components.
Surely there's a list somewhere out there, but I can't find it.
