zenolee Very cool. I learned a new term: Rinko compatible. Do you plan to remove the handlebars from the stem or the stem from the adapter? Especially in the latter case it's a new-to-me 'excuse' for an innicycle conversion. You don't need to worry about resetting handlebar angle or messing with threadless headset preload. Or dealing with a greased up quill stem wedge and height adjustment.

If we ever get the chance to meet in person, beers, snacks, dinner, whatever. It's on me.
