mdithey, You may need to adjust the chain line, in particular if the sensation is more pronounced at one extreme. No way I could diagnose from this distance, but my triples' middle chain ring traverses the entire width of my cassettes without a murmur at the extremes. My guess is that you will have roughly a 27-89 GI range. Certainly good for some hilly light to medium touring, my light touring/distance bike (road race) has a 32-98 GI range for comparison.
