I was riding my Baja Warrior, MB200, whatever you want to call it and the axle nut came off. The axle bent and I ordered another. But of course the axle did not come with a nut.. I have searched high and low for this thing. Online, Home Depot, Lowes, ect with no avail. Its a chinese bike so I am thinking metric. 14 mm doesnt quite fit though and no shops have 13/15 mm so far. Also, it has a finer thread than most nuts that I have been seeing. Any help would be greatly appreciated!
