wired vs wireless talks about the wheel pickup sensor. Wireless still has a wire going to each hood for the switch that gets covered by the HB tape, except for the very center that can be quite well hidden with placement and a few small wire ties.
There should be one wireless and one wired, with slightly different numbers, and there is a separeate number for the flitedeck computer and the mount/switch/pickup unit.
I THINK the correct numbers are...
SM-6501 for Ultegra wireless bkt & Sensor
SM-6500-RS for Ultegra Wired
SC-65xx computer - check to verify if you have double or triple ring, I think some work with double, some triple. There are several models - heck, they probably have one out there for 10-speed already to think about too....
