I have to admit I haven't posted here in a long time. I read and lurk, but haven't had much to say.
Anyway, I have one-of-a-kind bike. It started out as a hybrid, but I took off the straight bar/gripshifters and put on a drop bar with 105 STI shifters. I had to swap the out the rear derailler (it was low normal, not high normal) to make it work, but I've been riding it for over a year now. I have road bars and shifters with an MTB drivetrain, which uses Shimano DeoreLX Hollow cranks and bottom bracket.
I'm considering putting a road group on it, replacing the MTB triple with a 105 triple or Ultegra triple. Is the DeoreLX's bottom bracket compatible with an Ultegra or 105 crankset? If I need to replace the BB, is the threading compatible with what I'd need for a road BB?
