Not sure if those are sized for 1 1/8 inch downtube. Specs lower down on the page pointed to by the link say 22.2mm with cable. "Product Description
SHIFTER ROAD SET ACTION STEM W/CABLE 22.2MM STEM MOUNT&CABLES"
That's definitely a stem mount and will fit standard hbar stems. So they should work. The thumb shifters for the top bar can be found also. Falcon and SunRace make some friction ones that clamp down.
