Standard BMX chain is not 415. 415 is actually kinda hard to find locally, believe me I've hit every bike shop, motorcycle shop, farm supply shop, machine shop, etc within a 50 mile radius of me with no luck. I have been told that if you have a LBS that handles high end BMX you might fine it there because the guys who do the big air tricks use it otherwise its obsolete. There are places on line to get 415, I've gotten a few from Mike Simpson. I don't like the cheap chains that most kits come with, I've broken two of those so far, now when building a bike I put a 415 on from the get go. A good single speed chain will work but will look smaller than the cheapy chineese chain but is stronger. Another cheap sorce for single speed chain is your local garage door fix-it man, the last chain I got from him was a 10' length of KMC for free...Kelly
