My X2 make the Hope buzzing sound when braking hard. Love that, once you hear it you will love hope. Im considering getting the M4 evo for my new stumpy fsr. Hopes are so easy to bleed, very similar to bleeding a dirt bike brakes.
Is there such thing as a quiet wet brake? They are quiet when set up properly with the right rotor. The stock organic pads are some of the better organic pads out there. They are quieter and thicker than the EBC Red pads that I tried. The Hope Floating Rotors are "floating rotors" and will develop play at the rivets. I didn't like this. The Avid HS1 is a repectable quiet rotor for the X2.
