Would love to search the archives but I am at work, and sneaking a peek at TE.com cuz I am addicted....

LBS all say they have to have my bike overnite to do a tune up on my gears/deraillers. I really hate leaving my baby with strangers and besides, I can't ride tonite if I do that.........

Anyone adjust their own?? Is it "easy"? By that I guess I mean, can boneheads do it?? (me being the bonehead). And can I get instructions online?? Reason why I shouldn't attempt this??

Any input is greatly appreciated!!!
