NVWOCI WVS Posted September 27, 2007 Report Share Posted September 27, 2007 1/2 inch or 9/16 inch. all trials cranks will be 9/16 inch. i think possibly 24tpi but im probably wrong!(im sure i'll be corected) Quote Link to comment Share on other sites More sharing options...
ManxTrialSpaz Posted September 27, 2007 Report Share Posted September 27, 2007 What cranks you got? Might have pedal inserts (Small rings that screw out which the pedals screw into)? No idea on the size though. Whip out the good pedal and get your tape measure out. Quote Link to comment Share on other sites More sharing options...
