Just for confirmation, yes, the road stem was out there. One can be seen on the "Yeti Road Projects" features in the 1996 and 1997 catalogues. They didn't sell well, and a few have passed through my hands. I have one on one of my own Road Projects, but that is it. Sorry if this doesn't help much, but perhaps may motivate you to keep up the search knowing they exist.
26.0 though remember, so not good for Cinelli bars. Or as an alternative, some retro bars such as Scott and some 3t, were (and are) actually 25.4 out of the crate.
Good to hear that they are actually out there. I Will keep looking. I May convert the bike (quantum ii) to ahead and run one of the 10degree 1" zooka flipped over. Need to be one of the old with sticker logo so it can be changed.
If you bump info one, please have me in mind.
