Brake fade/frame flew
Got a Question-
I currently have XTR V-Brakes. I have heard many people talking about frame flex occurring with these brakes(and others). My question is, how do I know if my seatstays are flexing? If I look at them as I brake, will I see something? Do I just need to assume they are flexing if I get poor or fading brake performance with the brakes? Most of my riding buddies have brake boosters and I am thinking about getting a set, but am wondering if I really need them. Any responses would be appreciated. THANKS!
