is my crank is more or less junk?
I haven't ridden my bike for about 2 years now because of this
I think the picture will tell almost everything
and the crankshaft bit it attaches to is already a bit more of an octagon than a square
it just started creaking one day and on the same ride it started wobbling around for about half a cm. My knowitall uncle tried various spring washers and stuff but it didn't help.
the side with the gears is ok though
this thing is shot right? what all exactly do I need to replace?
