Fettling my latest build at the moment, a Planet X Uncle John CX frame... with wheels yet to arrive I've put together a few bits & pieces - do you guys think this drivetrain set up will work ok?
Ultegra ST-6510 STIs (9 speed)
105 double front mech (FD-5600)
cheap s/taper Acera compact MTB cranks with inner removed and running 9 speed 32/44 rings
long cage XT RD-M750 rear mech
11-32 HG50 9 speed cassette
The LH STI has five positions which is going to be helpful, but I'm thinking the front mech will struggle to push out far enough to run smoothly in the higher gear while on the 44 ring, and I'm going to need the shortest BB possible.
