Best praise vs top criticism for Giant TCR Advanced Pro 1

Best Praise

+10 pts

“That generation of di2 is dead and buried, any issues with it you’re in for new shift components, which will be hard now disc has taken over. Tcr, just because I prefer that generation of sram. As an aside, that period was when a lot of pinarello frames were counterfeit.”

“I'm super embarrassed by that, trust! It's been a struggle to feel comfortable riding my TCR for the last 4-5 years. My feet get numb, calves cramp, hands hurt, back hurt, etc. 🤣🤣. I'm quite confident it's mostly a fitment/stretching matter. Worst case, I'll get rid of the TCR and buy an endurance bike instead.”

“Low end Shimano group set. How old? Roubaix is a prestigious name in cycling competitions but I don’t see anything outstanding in this bike that would warrant $650. Way too expensive.”
