I'm only fussy about the chain, because of being nagged by my LBS about it. Oh, it didn't help that I ruined my cassette by not looking after the drivetrain. I reckon it's cheaper to replace a well-maintained chain, than it is to replace a cassette.

My bike is not getting any younger & alot of wear and tear was caused by a year's worth of lack of maintance. I'm not going to let it get any worse - I can't afford any major repairs.

Happy riding
