Ritchey Girder ISO559 rim cracked at eyelet
This crack is lengthening. The black dots marked the furthest progression of these cracks upon prior inspection, but one can see now that the crack tip has traveled on the left side (away from the spoke nipple) past the dot. Conclusion: It's time to retire this rim, even though this is the only spoke hole on the rim to show cracking. Cracks get to a certain length then can suddenly grow, possibly causing complete failure of a structure, rendering this innocuous-looking crack a safety hazard.
