I'm in the market for some new brakes! So let's here what everyone is running. What kinda of riding do you use them for? How do they hold up in hot/cold weather? What size rotors are you using? Basically the pro's and con's. So lets here it :bang:! I currently am running Hayes 9HD's on my bike. They really are a good brakes for the price. You can find them for really cheap now. It just seems sometimes when I really wanna stop there not enough.
