I changed out my chain a bit ago, and my friend who works at our lbs told me that when I change my chain I should place the wheel in the middle of the dropouts, have the chain be slightly longer, and not have it in the front of the dropouts(where it usually is).
Over time, the more I started skidding, I guess the wheel was progressivly getting closer and closer to the front causing the chain to becomes looser and looser, until it jumped off the chainring yesterday causing me to get into an unpleasant situation. Might I also add, since putting the wheel here, the chain has fallen off 3 times in the last month.
So, was there any logic to having the wheel placed in the middle of the dropout? It just seems like putting the wheel in the front of the dropout is a better idea since it's moving towards that point anyway, and this prevents the chain falling off. Where do you guys have your wheels placed? Does it make a difference? Maybe we just installed this on really badly..
