Provides ultimate brake power and allows you to precisely modulate the braking on carbon rimmed wheels. There is no squeaking and very slight wear. While Swissstop Yellow King Pads were designed for carbon fiber rims, you can also use them with your non-carbon rimmed wheels. The compound of pads gives you incredible stopping power in both dry and wet conditions.  You'll be amazed at how these pads actually improve your ability to feather brake as well as stop on a dime. You receive four (4) pads with each order of SwissStop pads.
