Picked up a R400 that needs the downtube shifters. If you have a set laying around, send me a PM. Prefer to keep it stock with the RX100 7-speed index shifters. Downtube is the large 1.625" diameter, not 1-1/8".
I actually have the levers, but I'm missing one curved spacer and one black plastic spacer and one outside screw. I have the rod that inserts through the tube.
A standard rx100 off a steel frame won't work, this frame requires a spacer of a different diameter.
Couldn't find anything in the QBP parts catalog.
Thank you in advance.

In the past I've mounted steel-frame-curvature curved metal spacers to run dt shifters on fat-tubed aluminum frames. Specifically used to have this setup on my Raleigh (http://www.unc.edu/~cupery/pics/bikes/Raleigh_aluminum/50_13-Raleigh_bike_in_2002.jpg). However, the Cannondale is different in that it has the black plastic spacer, which I thought was built into the frame. I've asked a similar question about a Cannondale that I'm working on - because I think you need a flat metal spacer that interfaces with the indexed lever; the flat metal spacer would fit overtop of the black plastic spacer that sits against the frame. Here's my thread (with pictures):

My shifters were screwed together with the support rod OUTSIDE of the frame. So I know on my frame, the shifters come off the bike easily. Obvious parts missing.
For what its worth, the CD I have has the plastic cable guides on the top tube that come off (or break off:D ).
