I recently sprayed my bros bmx and removed the stock 1pc cranks he is looking to purchase 3pc cranks but can he purchase any 3pc crank or does it have to be a certain one. I noticed the hole on his is slightly bigger then mine DK Six Pack 08
This is the hole on my bros
you wont really come across to many unsealed 3 peice sets. there are cups pressed into the frame in that shot. they are the unsealed bearing races, pound them out with a hammer and a flat head before installing new cranks.
