I kept snapping chains until I checked my derailleur hanger alignment

Spent a whole weekend replacing a chain on my old Trek only to have it snap again after 3 miles. Turned out the hanger was bent maybe 2 degrees from a crash last fall, and that slight angle was binding everything up.

2 degrees seems like a tiny amount to wreck a whole ride.

Laughing at myself because I thought the same thing until I tried to parallel park with an offset trailer at a gas station. 2 degrees turns into a 20-foot swing real quick when you're backing up. I once jackknifed a U-Haul so bad trying to correct a "tiny" angle that I ended up blocking the whole pump lane for like 15 minutes. Felt like a complete idiot waving at everyone honking at me.
