You need to remove the coin, silly!
Sorry. I wanted to resist, but you tempted me ...
(Aka: Look what you made me do)
Just and armchair engineer diagnosis here: A few posts above, there is a picture of what seem to be spacers with the same pattern as the spider's interface. Maybe those have to be used? Really just guessing, I don't have the cranks.
Those photos are from BigRock crankset. I just recieved mine today and they came with spacers for spider.
From what I can tell these seem to be good quality and spindle isn't out of spec like some have reported to be the case with other brands 24mm cranksets. I measured the q-factor to be ~146mm wich is ~1mm wider than advertised but it's still narrower than most cranksets offer.
Unfortunately I can't install them since bb I ordered is stuck in the mail sorting center. Hopefully I'm able to figure how to install them and chainline hits the spot.
