I've been keeping an eye out and haven't been able to find much. I have a gravel bike that has fully internal cable routing but the handlebars have 80mm of reach and I would really like to use something shorter (70mm or less). In a perfect world, I would basically want a Salsa Cowchipper handlebar, only with holes drilled for internal routing. I'm a big fan of the Cowchipper's wide flare combined with shallow reach and drop.
