About 4 months ago I would have said superstar kevlar are great. Latest batch have me absolutely useless and as I installed them after the 45 day “no quibble return policy” superstar won’t take them back. So poo them.
However, I am running sintered and they are OK.
I ordered 4 sets of the race matrix pads after reviews on here…. They were absolutely terrible. Improved in the wet but, squeeled like a pig and so inconsistent. Nothing…. Nothing…. Nothing…. Oh balls….. Bite, skid wallop. Stuck a new pair in my cx with rs685 hyros…. Awful. On the 69er….awful….. On the bouncer… Awful (slx, XT and rs685s)
I have never had an issue with oem pads so for now, I am back to using sintered shimano pads on all my bikes.
