Loosens themselves, difficult to self service.
"They were great pedals, until they weren't. Satisfied with them as a contact point in wet and dirty conditions requiring relatively high torque output. Especially for a pedal that doesn't tear up soles on pedestrian shoes The loose bearing balls inside make this extremely difficult to repair on your own. If you put any serious mileage on them you will run into a clicking sound coming from the crank area, further investigation revealed the pedals have loosened themselves and now play back and forth on their own spindle just a bit. Causes the rubber seal on crank side to pop out and allows grime to find its way inside. You likely won't notice until its a larger problem. After I had fixed the clicking issue by taking off the outside plug and adjusting the tightness of the nut just enough to remove play and not increase resistance, they got tight and crunchy on their own after a short 1/4 mile ride. Took them apart completely this time to find loose balls instead of actual bearings, balls are no longer in the right spot, perhaps due to the improvisation needed for complete disassembly. Re-greasing and re-assembly is frustrating and tedious, and I'm a precision machinist by trade. Good pedals for the couple hundred miles I put on them, but I shouldn't have to do this at such intervals. Form and function like high quality pedals, but internals not built to last, and certainly not to be serviced, and you will likely need to at some point, unless mine were lemons."
