+1 Oldfart (you really need to change that name) a tool is exactly what it is. There is science to everything, and I like science. Raw talent is no longer something special. Now days there are too many athletes with raw talent so to get that little extra edge they have to rely on science and precision.
If you want a level playing field why not ban shifters and only race with single speed. This ideology of not allowing new technology is primitive and anti-evolutional. I know when I was racing I relied heavily on my HRM during races to make sure I didn't blowup and in training to see if I could get a couple of more bbm. If I had the extra $s back then I would have definitely invested in one and still might, as soon as I get done winning the justification argument with myself.
