I have a leader 735 T (older, discontinued model aluminum frame) frame I believe its between 3-4 years old, I want to get an ordinary 700c clincher wheel set up preferably with a fixed/free hub. The previous owner had a standard 120mm hub fixed/free wheel on the back, and had to tighten the rear until the dropouts flexed in (which worked enough, but caused problems). Anyways, can anyone confirm the actual spacing of the rear dropouts of this frame, and give me any info on this frame and its purpose with this non-standard spacing? I measured about 140-145 mm spacing
