I use a dab of Blue Loctite on my chainring bolts ( and the mudguard stays etc ) I even had a Nyloc bolt eventually vibrate free ( on the suspension block fixing bolt on a Brompton) so I used loctite there as well. Loctite Blue isn’t a permanent fix like the 638 and similar formulations.Having discovered that two out of three of the Scott's chainrings were attempting to go AWOL, I'm awaiting a proper chainring bolt tool from SJS.
Is that it, apart from more regularly checking, or is a dab of some threadlock a good move?
TIA.
