I've been to 2 different bike shops (both w/ good reputations, sell good quality gear), and have gotten different answers as to why my shifting is less-than-desireable.
1 shop told me that a road bike chain needs replacement every 1-2k miles. Another first told me that the problem would clear up w/ just a tune-up.
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!
