Yup. The issue is chain rubbing on the inside of the big chainring when using the small chainring and the smallest two or three rear cogs. I get just a touch of chainrub in my third smallest cog with my Klein and generally hunt for a different combination rather than ride in the second smallest. I still like it better than any of the alternatives that I've considered.
