Bought 2 sets this year in januari (Hayes Nine version)
Biked 2000 km with the first set, 500km with the second.Only 500 due to one 90km track with a lot of rain and sand.
They were halfway at the beginning of the trip and 20 km before the finish the backbrake was only steel on steel :(
So if you ride in dry circumstances these are good
Only for dry weather
Backplate is to big due
Not tried the pads yet, this review is purely regarding my service from superstar. Ordered 4 pairs of pads. On delivery it was immediately obvious that Superstar had sent 2 pairs of the wrong pads. I was told to return the pads, and they would send new ones out. Returning the pads appears to be at my own cost, as the postage was never refunded - even though it was not my fault.
