Got a frame with a downtube that has an external diameter of about 32 mm. Plan was to install clamp-on downtube shifters, but needless to say this sizing screwed me over big time, as the standard is 28.6 mm.
The reason I wanted to go with DT is that they are literally dirt cheap. STIs and bar ends would cost at least 5 times more, and this is a next-to-no-cost project. There are no adapters I could find, or if there are, they cost about as much as a pair of STIs.
How would you guys bodge this together? For the time being I'm going single speed but that won't cut it in the long run.
