install shimano sti shifters?
i have my new ultegra 6703 shifters, and i want to install them.
i have removed my bar tape, and now i need to remove my old 105 shifter.
i have read that i am supposed to use a 5mm allen wrench on the outside of the shifter - both to remove the 105, and to install the ultegra.
i have spent a while looking, but i don't see anywhere that the 5mm allen wrench can go..., either to loosen the 105, or to tighten the ultegra.
help...
