well you might have caught my thread about flats i just posted. i think i fixed that. my stupid DP18 has these little holes on the side of the rim (not spoke holes, it has to be a defect), i covered those up better and went to put my wheel back on. while adjusting chain tension i cracked some sort of washer type thing. 2 of them. is this my lockrings? i have a flip flop hub and i think i cracked one on each side. like i said it looks like a thick washer.
