I need some help with making sure I have the correct parts before I tear into this bike for my girlfriend (that currently has a 2x9 hodgepodge setup). I am a fairly novice bike mechanic but I want to tear this apart and teach myself how to do stuff, and eventually when I screw it up I have some friends that will help me with all the final tuning.
Currently I have an ultegra 6700 crank and the front/ rear derailleur from a 2x10 bike that I upgraded to 11 speed. Since it was used for a TT bike I don't have the shifters/ brakes. My plan was to grab either some 105 or ultegra road shifters to use and finish it off with a new chain and cassette.
Would I run into trouble trying to use a 5703 triple front shifter on a double crank? Or can that even work? I have heard both ways from different people now.
Adapting the BB will be my next challenge, currently it has this (BC1.37 x 68) and I want to make it work with a BB30 ultegra crank that I have:
