New to all of this, so I don't really know the terms. Bear with me.
Got a bike from a garage sale about a year ago, in nearly brand new shape, haven't really rode it.
Over the past few months I've been using it quite often, biking roughly 8km to and from work.
Yesterday, the chain was skipping, and then later fell off of the largest front gear, to the right. Since then, if I put a heavy load on the pedals, such as biking uphill, or attempting to accelerate really quickly, it will fall off.
I've looked into fixing the front derailleur, and played around with the two unlabeled screws out front, but had no luck.
The chain still falls off due to heavy load, regardless of the position of the screws adjusting the front derailleur.
Unfortunately, I an not too sure if my front derailleur is properly "calibrated", and was debating on playing with it until the chain maybe fell off less? I seem to have gone through a bunch of options with no luck.
I'm assuming that the front derailleur isn't he problem, or that I should keep adjusting it until the problem stops.
In conclusion, I am not too sure what to do. Do I seek a new problem, or do I continue adjusting the front derailleur?
