I hate Shimano stuff because I had a boss at a former job who rode nothing but and always talked about Shimano components. I didn't like him and for some reason Shimano reminds me off him. I avoid Shimano. I built my current roadbike avoiding all Shimano components even if it mean missing out on a sale and paying more for Sram stuff. The only Shimano part on my bike is the FD braze on bracket and I don't like it.
