I recently upgraded my old Kona Kikapu with these Hayes disc brakes and I am impressed. These are my first foray into discs and I decided on these because of the Hayes name and the excellent price. I was a little concerned about attaching the Sport's to my bike because of my inexperience with disc brakes, but my concerns were misplaced. They were easy to mount with the Hayes adapters I purchased and I learned how to accurately centre the rotors in the pads. These brakes come with the 'Crosshair' adjusting system which makes centring the rotors a breeze. It only took ten minutes to have my wheels spinning rub free. The cables were plenty long enough to fit my bike and I love the brake levers. They are solid, look good and have adjustable reach. One finger does the trick to bring your bike to a fast quick stop. All in all a great pair of levers. I highly recommend these brakes. Overall this is a great purchase and a huge improvement from rim brakes. So far I have found these brakes to be strong reliable.
