Why We Like The Dominion SFL A4 Disc Brake

Made for the fun in life, the descents, the Hayes Dominion SFL A4 Disc Brake is built stiff and burly for the most aggressive of riding. Proven on the downhill world cup circuit these brakes are more than burly enough for our uses. We trust these brakes on the most aggressive and high-consequence riding we get ourselves into.


  • Aggressive downhill brakes for hitting the burliest lines
