*I missed the fact you are actually using a triple with only the middle and inner rings. Same math except Front triple CL = 46.0 mm for the Middle Ring. I dont know the Middle to Inner ring spacing, but on my XD2 is is about 8 to 9mm.*
*A front CL of 46 and a rear CL of 42.5 (130mmOLD) places the Middle Ring at the #4 Sprocket, so Middle to #8 and #9 has increased wear.* *Your ACTAUL Front CL and Rear CL may be different from assumptions. You can measured both and use the same method.* John, I appreciate both your thoughtful and detailed responses. I'll definitely give it a look and do some measurements...there's nothing I'd love more than to put numbers to the situation so I can know exactly how much more wear 8 and 9 would be getting in the big ring.
