Is Sram more difficult to set up than Shimano? Or are mechanics often just less skilled with it, or have less patience to set it up correctly? While not "common" there seem to have been a few Sram AXS bikes bought of late with what seem to be serious setup/ installation issues that don't match what I've heard on Shimano, even with more Shimano sold. I'd be spitting fire and blood if I spent $14k on a bike and it was leaking and rubbing the chain. I'd be pissed if it happened on a bike that cost half that... or a quarter.
