I just completed this conversion using the FMF adapter. Everything went together well but I was challenged to figure out the correct BB length. I tried a couple of traditional BB that I had and neither worked. I ordered a 121.5mm Shimano cartridge BB from Harris but it was too long, but it then allowed me to measure and determine the right size, a 110mm. But is this the right size for your Continental? Probably not. Reverborama used a 107mm cartridge. It all depends on the crankset that you are using. If you have a friendly LBS nearby, I'd take the bike with the adapter installed and the crankset you plan to use and let them fit the BB.
