Not true, but proper stack and reach on a too small bike might cost as much as a fitting. I have commuted many miles and years in perfect fit on bikes with reaches too short for my very long arms. I have local framebuilders make me custom stems. (2) 180s, a 175, and a 155 so far. Much, much cheaper than the custom frame to get the same fit. Every once in a while a stock frame shows up that works with a 130-140. Big fan of Nitto 130 Pearl stems - 140 in the conventional measurement.
