6.67 X 4.4 = 29.33333

29.333333 x .389 = 11.41

I trust that I'm doing something wrong as I haven't had any experience with this but I just can't see where..could you point out my error?

Thank you so much for all the help you've provided.


Yeah, I figured that the change in ratio was due to the cassette I just didn't think about the internal gear reduction at first which was throwing me off.

Conradcliff, you did good.

The 6t/40t, 10t/44t and 36t/14t is EXACTLY what you need.

Now ya just have to locate the 40t sprocket to accept a #25 chain.
