here's my tuppence worth...
Riding pair of stainless mk1 beaters for 7yrs without issues and no servicing-of course cleats wear through but that is what they do.
Unfortunately i smashed the cage while radding it riding 'dreamtime' at CYB and thought that's that. However 2pure spotted a whinging post on here and offered to warranty them so that's nice service.
I also sent of a pair of candies which had the cage smashed too and i hope that these are repairable as well.
I have always liked the quick and easy access into the pedal and the simplicity of design, but it seems that the newer pedals are built cheaper than before therefore failing more commonly?
