Can I customize the components on a BMC Roadmachine RM02 without voiding the warranty or completely undermining the bikes intended design, and if so, what are the most critical components to upgrade for a tangible performance boost, or are we just throwing money at a problem that doesnt exist in the first place? It seems like every Tom, ****, and Harry is swapping out components left and right, but are they really getting any faster, or is it just the placebo effect at play? Does BMC even care if we start tinkering, or are they just banking on the fact that well be too intimidated to touch the thing? If I were to, say, upgrade the crankset or swap out the wheels, would I be gaining any real-world advantage, or would I just be spinning my wheels, pun intended? And what about the argument that the stock components are good enough for the average rider - is that just a cop-out, or is there some actual science backing that claim up?
