Do they even exist??? I'm seriously considering buying a Planet X Kaffenback frame as a winter road bike, cyclo cross and light tourer. The Kaffenback doesn't have bosses for downtube shifters, and -- due to funds -- I wouldn't be able to afford expensive STI or Ergo levers. However, I have a few sets of downtube shifters and I was wondering if I could some how fit them onto the downtube with some kind of clamp that has the bosses. Like 70's road bikes had band-on downtube bosses.
I know you can get "Pauls Thumbies" for donwtube shifters that mount on the handlebar n' all, but they're expensive too (£45 - 50).
