Totally, and to the max.
My wife's bike is a Giant Trance 1 and I set her up with some bling brakes. I was pretty careful to install the brakes properly, making sure the spacing was dead on. They were good for a while, but have since been making the most god-aweful racket. I thought I'd heard that this was common with Hopes, but I'm wondering if maybe it's just the stock pads that may be too hard. Any advice?
