It's satisfactory now and, frankly, even tho' my gears (44/30 X 14-15-16-17-18-20-23) give me between 85" and 35", most of my riding is in the middle cogs (60-64-70-74 is such a lovely progression), so chain rub is far less of even a potential issue. Putting 10 cogs on would definitely make adjustment harder.
Oh, and 8 sp chain, btw. 126 mm bb? Mine is an asym 115 with the Ram's 132.5 rear spacing, and it works fine. You must have a triple?
