This is something I've asked in the past and was told in various ways that it's not possible...but then I saw this in San Francisco. It can be done!
I'm just wondering if anyone has any advice on how to go about it. I notice the Ritchey logo, looks like one of their time trial models, so perhaps this guy has a road stem as well? If that's the case perhaps it's just a matter of hacking on the brakes and shifters.
I actually found a few 25.4mm bullhorn bars - anyone know of some good places to find more of these? I'm looking for a more flat bullhorn, not one that's sloped downwards so harshly.
