I was wondering about something. Do the different rotors actually make a difference? Like if you visit the different manufacturer sites, they say "optimal rotor design for maximum performance" but all worded differently. Do they really make a difference? The holes patterns, hell, the Hope gothic rotors don't even have holes. Look at how differently all the major companies rotors look: Avid Hayes Hope Shimano I left out Grimeca cause I couldn't find a pic and same with the Magura line... But even the Mini's rotor differs from the M4...it makes you wonder... LOL....dumbass question I know, but maybe somebody really knows that has tried the different rotors and had different results from rotors alone.
