I'm building up a bike to leave on my KK trainer. I'm building it up as 10 speed, but I can find some great deals on 9 speed ultegra and 105 cranksets. I've never tried it, but I've heard that 9 speed and 10 speed cranksets only differ in the thickness of the chianrings and both will work with the narrow 10 speed chains. Considering my indoor use, does anyone know if this will work?
