Can a Giant TCR Advanced 2 really be customized to fit my specific needs, or am I just wasting my time and money trying to turn a mediocre bike into a dream machine? Ive seen people swapping out components left and right, but is it really worth it? Is the TCR Advanced 2 just a cookie-cutter bike thats meant to be ridden off the shelf, or can it be transformed into a bespoke speed demon with the right tweaks? And whats the point of even trying, when Giants own engineers have already optimized the design for maximum performance? Are we just deluding ourselves thinking we can do better?
