First off, let me apologize if this has already been discussed or if this is not the correct forum to post this question.
I did a few searches and didnt see anything like it so maybe the community can help me out.
With all the different bikes and components out there, how do you know what is good and what is crap?
Is there some sort of component rating system that tells you A is better than B but not as good as C?
Is there a list that ranks components from 1 to 10? Components like cassettes, levers, derailleurs, etc.
Any help is appreciated in understanding this better.
