Another question on a bike I am helping to upgrade:
It is a 2004 Trek 5200 with a Octalink V1 bottom bracket, Ultegra double crank, 53/39.
We are wanting to put a Dura-Ace FC-7900 crank on it so obviously the BB won't work as is.
Can a Dura-Ace 7900 Hollowtech II bottom bracket (SM-BB7900B) a direct screw in replacement into this frame? (If not that exact one, is there a BB that I can put in this frame to accept the FC-7900 crank?)
Any other gotcha's I need to be aware of?
