DOH! I guess I should have known.

I've never bought a Nitto product but I've come close to it. And they DO make stuff that saves the old school crowd. To my mind the Dirt Drop stem would be more in keeping with a set of bars that are needing to be put up higher for comfort. The trick will be to stuff the slightly larger road bars into them. Something that a little time and care with a drum sander in a hand drill would manage.
