I have a Specialized Tricross which I bought new last year.
In that time (approximately 1K miles), I wore out my chain and gears. At least two of my gears are still slipping, even with a new chain.
I think I spend the majority of my time in one or two gears. Should I avoid this? Are there other things I should be doing to avoid replacing my chain/gears every season?
I am a novice who mostly just commutes to work, so assume I know very little about form.
