I have just built a retro micro low pro time trial bike, based upon the tiniest little frame you ever did see and a 24 inch front wheel, but I'm not happy with the shifting. Last night I did my first tt for 30 years, only 5 miles but long enough to shake the bike down. As it's an older steel frame it has a single shifter boss on the downtube and I currently have a Shimano 600 7 speed lever attached to it. However, reaching down to shift whilst blatting downhill at approaching 35mph in a low crouch is not to be recommended! Wobbles are the order of the day and I don't fancy a spill at that sort of speed, so an alternative has to be found.
I've found that a pair of retro-ish Tektro band on brake levers can be fitted to work as reverse levers so they will fit on the bullhorn bars and allow a bar end shifter to be fitted on the right. Ideally, I'm looking for an Ultegra/600EX 7 speed version, SL-BS50 is the model number, but I'll consider anything as I may have to get the rear triangle cold set to 130mm to accomodate an 8 speed hub. If anyone has the SL-BS50 but only as a pair I'll take them.
