Can anyone tell me what the thread pitch/ size on the bolts that sit to the right of the crank pully are? There are 2 of them , using them to mount a crank sensor but one of mine is missing and nothing I have seems to fit !
They will be imperial. Measure the diameter...probably 1/4". They screw into aluminium so will most likely be a coarse thread which would make them 1/4 UNC.
