Spacers on crankset without info
Hey,
I just got a crankset from China and wondering how many spacers I need and what distribution. Since the crank is from China im not surprised there isn't any information on that whatsoever. Got a 68mm BSA30 and the crank can also be used for 73mm shells so I definitly need spacers. Is there any way to measure it and compared it to something similar or is it more like try and error?
