Why is there no mention of the specific bike’s stack and reach measurements and the rider’s measurements?
Since many modern dedicated tri frames HA is in the 71-73 degree range, If the frameset’s size is small enough relative to the rider’s size, is there really a non-aero reason any road (or even gravel?!) frame cannot just have a zero-offset seatpost, a short stem, some drophorn bars with aeroclips mounted and be perfectly fine for their first few years of racing?
