I've had my road bike for three weeks now. The front mech worked well for the first two weeks, but this week, it has begun dropping the chain. I've now dropped my chain six times in the past three days. Each time I adjust the front mech, it seems okay until I ride it a bit, then it starts dropping the chain on the up-shift. It's as though the upper limit is drifting. I've tried setting the limits a little tighter, but then I can't shift into the large chainring. Do I need to tweak the tension? Add some threadlocker? Get the limit set just right?
