I''ve been struggling with 26-13 standard-6 speed on my Masi for a while, and I think I got it. This is a really short chainstay. I found I could not get the correct chain length by adding or subtracting a link, so I fell to adjusting chain length and whether it tensions by moving the wheel forward and back. I think movingteh wheel back is equivalent to shortining the chain. I like to get some tension on 13-52 and no interference plus no excessive cage tension in 42-26. I found the magic spot for my bike, but I dont think I have the courage to go back and try to get a 28 to work. I've jsut barely kept the NR's cage from scraping the 26 tooth cog while still having enough tension to hold tight on the 13-52. My wheel is not pulled all the way back. I suppose I'd start by adding one link then moving the wheel forward and back to see if I can get the cage to rotate enough to clear the 28 T cog. If that will happen with the chain still guiding well when entering the cage, then see if 13-42 works, then get a rag handy and try 13-52. Maybe instead I'd shift to 21-52, then work my way down slowly to 13-52, watching for chain droop and chain throwing. Not pleasant.
Personally, I don't think it's worth it to get another 2 teeth in the back, and I am not sufficiently macho to have to say "I did it."
