I cannot seem to find compact drop bars in 25.4 clamp size. I am not able to change my stem (Schwinn-asonic Super Le Tour 12.2 frame with fork tat requires the odd 21.15 quill stem size) and therefore must find a bar with a 25.4 clamp size. I want a very compact set of compact drops but cannot seem to find this clamp size. Am I missing something?
