FWIW, the problem is that I get clacking sometimes when I shift the rear cassette, and also shifting between the 2 front gears, the chain pops off (about once every 60 miles or so- enough to be really annoying).
FWIW 2, the bike is never ridden in the rain, and here in Virginia, we really don't see dry & dusty conditions.
FWIW 3, The bike itself is a 1997 Bianchi CDI which, before the past couple of months, had only been ridden about 300(?) miles. I am the original owner (I now ride about 240-ish miles/month since Oct. 2006). I do know enough to not cross-thread the gears, i.e., small gear on small gear.
Thanx in advance- but please don't get too technical, I'm rather new to all of the terms!
The great thing about determining chain wear is that you don't need to know the mileage on the chain, the time on the chain, and you don't need an LBS' advice. All you need is a ruler..............Measure from the center of the pins. Over a span of 12 full links, a brand new chain will measure 12". Again, measuring from the center of the pins, when a chain is elongated to the point that it reaches 12 1/16" over a span of 12 full links, it's time to replace the chain. It's as simple as that. If you do this, the life of your cassette or freewheel cogs as well as your chainrings will be increased significantly-
