I have a square taper bb that binds up when I tighten up the nds cup/sleeve. It spins very freely when the cup is in there finger tight but when I tighten it fully there is a lot of resistance in the spindle (noticeable with the cranks on as well). As I understand this could be due to the poor manufacturing tolerances of the UN300 compared to the UN55 and bearings not being perfectly aligned...?
Would it be best to run the nds torqued up and put up with the resistance or run the nds a bit loose? Any downsides to the latter?
