I need to replace the chain on my 21 speed mtn bike (3x7). The chain on it now is a KMC Z-3J it also has the word narrow on it. I can't find any listing on this chain anywhere including KMC's website. Can someone tell me what chain size I need to replace this with?
My favorite is the Wipperman 808 because it's fully nickel plated and comes with the connex link. They're $20 from Lickbike.com. They all seem to work fine, I just like the corrosion protection and bling of a nickel plated chain.
Thanks for the replies people. I'll be going to the lbs today. I've spent several hours the last couple of days reading these forums and have learned a bunch. A valuable resource for anyone interested in bicycles.
