Hey, this isn't an actual question. I just put my frictional thumb shifters (cheap falcon ones) on the tops of a standard drop handlebar (like Rivendell shows with theirs) and find them extremely functional in this set-up. Much easier to use than downtube shifters that I had on there for about 2 years previously.
Anyone else done this? To me it seems like a perfectly viable ****ing position, simliar to bar end shifters in ease of use. I haven't found any potential pitfalls with it, but time will tell.
