I noticed excess slop in my MKS ezy superior pedals after about 4 years and about 25K miles. The bearings in the pedals themselves were fine and without play, but the quick release mechanism was worn. I could feel it with each pedal stroke. It was a subtle klunk, but was becoming more noticeable over time. I ride without cleats or toe clips.



I was able to buy some replacement pedal adaptors (the part that screws into the crankarm) for $30 on amazon. They came directly from Japan. Looking at the pedal shaft, I could see some wear in the indentation where the ball bearings of the pedal adaptors lock the pedal spindle (see picture). With the new pedal adaptors (and with the old pedal spindle) I found the play was much reduced, almost to like new. So I’m good for another 20K or so.



Next time I buy a set of these pedals, I will get a spare set of pedal adaptors with them.
