The Lexon crankset that I ordered and returned from "RYET Official Store" on Aliexpress came with no specific spacers for the spider.
Two washers for mounting the pedals and three spacers (0.5mm, 1mm and 1.5mm) for adjusting gaps and chainline.
Since the gap was 5mm in my case, +2mm more on effective axle length and q-factor, I returned the crankset (I was not offered a deal on partial refund from the seller).
Meanwhile I purchased and received the Rockbros crank with 24mm spindle.
93mm effective axle length and 151mm q factor as specified, axle color is raw titanium (vs. black color of the Lexon crank).
