Hmm. Interesting one. Perhaps slight over-extrusion is causing slightly oversize printed sections.
Where is the tightness - on the surfaces that rotate against each other with the pin or on the edge rubbing against the next link?

Perhaps reducing extrusion multiplier a bit to reduce the flow slightly and trying again. If you have digital calipers, some measurements might help?
