I have one on my tourer/commuter. My crank is a 5-arm 94/58mm BCD triple with the granny removed and the outer ring replaced with a 46 so I run 46/32 rings. My crank takes a square taper BB so I was able to get a slightly shorter one for better chain line as a double. Not sure if you can do that with a Hollowtech crank, though.

Or you could get this FSA crank and I think you could replace the bashguard with a 48 ring: http://www.universalcycles.com/shopp...s.php?id=30857
