I have a question! I replaced my chain about 8-9,00 miles ago and I am all out of adjustment ability. So I know I need to replace the Chain, but my mechanic says that you have to replace the Sprockets with it. Now the last Chain I put on there was no mention of this(different mechanic). The Sprockets don't show any obviouse wear, not even close to the cutouts in the Clymer book. Any opinions??? Or is this guy just yankin' my Chain? Punn intended !!!
