ok ill show you what im working with , i was sent these spacers with the frame , the spacers included a drive side which looks to be like .5 mm and non drive side that looks to be about 3 mm or wider two bearing shields and a wave washer .
my sram crank is pf30 and it tightens from the non drive side , but i have seen a few that tighten from the drive side so im confused on the difference , the sram crank came with what looks like a metal spacer and a plastic dust cap i think .
