De-gunker for Derailleur Hinges?
It looks like my clamp on 105 front derailleur top hinges had enough gunk build up that it stopped downshifting. I’m feeling quite lazy and hoping that someone knows a good product to dissolve the build up on the bike.
Failing that, I’m ok with removing off the bike and have it soak in warm water before I work the hinges till they move without resistance, but like I said, I’d love to hear if anyone has a product they had success with without having to remove the derailleur off the bike.
thanks.
