2. I’m considering buying a new frame, but can’t decide on the size. A size small will require minimal adjustment to the cockpit to get my RAD and RAAD. A size medium will take much more adjustment, but will result in a more neutral, slightly positive SHO. The medium will have a front center around 20mm longer than the small.
