I might have a beat up set of black pedals, you could always paint them, you’d probably want to rebuild them anyway. I’ll try and go through the “old stuff” bin, I’ve been on ATAC pedals for 15 years. I’ll let you know, no promises.
WOW Mix, caged pedals…That would be my guess why you are having a hard time finding a set. I know as a kid with the bmx bikes and using caged pedals they had a VERY short life which was the reason I started using the shimano DX pedal when it came out. From the first time you post that I look on E-bay and found their clipless pedals and thought that was the model and you were looking for, but a good deal…caged pedals…the only hope I feel is a set of NOS that somebody forgot about on the back shelf…Best of luck in the search .
