Use ONLY BLACK SPD SH51 cleats for fixed gear!!!!!
That's what the Shimano manuals say... But then I have silver cleats and they most definitely don't clip out when I pull up... No SPD cleat does
AFAIK. IIRC the manual also says that the "black" kind doesn't release inwards, only out... my cleat releases whichever way I turn my foot.
Can anyone make sense of the stuff Shimano say?
