Damaged LX chainring
I've lost the top off teeth on the middle chain ring on new LX crankset after 2 rides. The damage has occurred to the 2 teeth in line with both the drive and opposite cranks.
Could it just be a crap shift by me under load, the fact my chain might be stretched (not in a position to measure at the moment) or a soft chainring??? Should I be winging or improving my shifting?
Not to worry. That's actually a frequently asked question.
Examine your chainring more closely. You'll find some other sets of teeth that look like they have exactly the same kind of "damage". Those are actually shifting aids that are designed into the chainring.
