Front derailleur snapped mid-ride on Route 9, how I limped home
I was climbing that long stretch near Highland Park on Sunday when my front shifter went slack and the cage just folded into the chain. Turns out the pivot bolt had been corroded for months, I never thought to check it on my 2018 Trek. I ended up using a spare zip tie to lock it on the middle ring and rode the last 5 miles in granny gear, which worked but felt awful. Has anyone dealt with seized pivot bolts on older Shimano groupsets, or should I just replace the whole derailleur at this point?
