This triple is on my tandem. It was a little tricky to get adjusted, but it is working well now, except for one thing. I use the middle ring a lot, and it is my opinion that I should be able to utilize the entire cassette while in the middle ring. Do you think this opinion is correct? Specifically, I like the combination of the middle ring and the largest cog for climbing many of the grades in my area. However, I get bad interference in that combination. I don't consider this combination to be "cross chaining", but, is it? Thank you!
