if you meant me, I have some miche primatos i will be installing, but i like the look of Omniums but they require a different BB. Would this fit the Langsters frame?
da 7600's are designed to work with a 109mm iso bb, the 111mm iso ones are as close as you can get, i have one here for sale http://www.lfgss.com/thread116579.html it'll put the chainline off by 1mm but that little doesn't really affect anything, have a look at the "database" and you'll see most people use 111mm iso axle bb's
as for using a jis bottom bracket on iso cranks, it is possible but there's no real point if there's better options about...
for the miches, this http://www.wiggle.co.uk/miche-primato-track-bottom-bracket/ or this http://www.totalcycling.com/a-z/bottom_brackets/bottom_brackets_track/BB_KINEX.html?gclid=CPqRmL_e5roCFU7KtAodgUgAAw works fine, your langseter shell will be BSA thread, 68mm wide, you just have to make sure your bottom bracket is like that too
