Whats the most common roller chain norm for bicycles?

  1. Nov 13, 2011 #1
    I am designing a bike in Autodesk Inventor for a university project, and I am stuck with the sprockets. Inventor can create them fairly easily when you know the norm of the sprocket and the number of teeth it has, but I don't know the standard of the sprocket I have to design; I merely know that its about the same proportion of the rest of the sprockets I have ever seen in bikes, so which is the most common norm?

    Well I was talking about the actual ISO / ANSI norm used in the design process, the pitch diameter I was able to measure and the radius too (I only need one sprocket). Anyway, thanks for your contribution, after tinkering for a while I found a norm that seemed bicycle worthy enough.
