right pedal falling apart twice on my downtube 9fs.
the first time it happened the whole pedal fell off in the grass, i was only able to recover the pedal and some of the tiny ball bearings. the nut that holds them together was gone, i couldnt find it. luckily I was still within the downtube warranty period so i got a replacement pedal from downtube.
the second time well, this is the new replacement peday i got, its coming loose again. i feel the pedal feeling a little grinding and very very loose, so i open the cover and see a nut there, tightened it but i couldn't, it must be shredded. i went to home depot but i can't find a nut that would match the tread. the tread seems fine, just the nut is bad. so i guess all the pedals falling apart, the nut maybe the culprit.
So my question is what is the nut size that hold the pedal together, i am trying to put my pedal back together.
