... you can always get caught out.
This morning, before I set off on my ride, I thought I'd paint my gold anodised chainring bolts orange so that they match the rest of the bike (didn't want to fork out for a set of orange chainring bolts (would need 2 sets too); used Tamiya clear orange paint for indicators).
Anyway, for some reason I decided to grab the inner ring only to discover it was lose!! Seems 2 of the bolts had come undone; never had an issue with chainring bolts and never checked them but now I will. A bit of loctite sorted it out.
