I too use 1185mm tire circumference for my 16" x 1.50 Marathon Racers on my curve.

You should use the true tire diameter instead of 16" in the GI calculation.

Tire circumference = 1185mm
Tire diameter = 1185mm / pi = 377.2mm (14.85")

For 3 smallest sprockets on your Capreo Curve SL you have-

14.85 x 53/9 = 87.45

14.85 x 53/10 = 78.71

14.85 x 53/11 = 71.55
