Best Brakes ever! - May 11, 2013

5 out of 5 stars

I went from a dual piston caliper from a different manufacturer to the single piston XTR and somehow my stopping power is greater. Two is not always better than one. I bought I-spec brackets to mount my XTR shifters to them. They look and work great together. They come pre-bleed but I shortened the lines and bleed then. It was easy. I have the older XTR brakes and they were easier to line up the caliper to the rotor then these. But the stopping power of this new generation is greater. I have several bikes with different brand brakes. I will only buy Shimano from here on out.
