Racing Numbers

This is an image from the OKC Pro- Am Classic 2016 race that my youngest son( who is 7) and I attended on 6/3/2016 at 6:30 pm. Numbers play a big role in this sport. These are 18 – 35 year old women riding 50 – 54 cm bikes that cost anywhere from $2000 – $15k. The athletes push down on the pedals in a cadence specific to each rider at a predetermined revolutions per minute (RPM). Over the past 10 years, the number of gears on road bikes has steadily increased. Current groupsets now provide up to 22 gear combinations produced by 2 front chainrings and 11 rear cogs. Gear inches provides the diameter of a wheel that has a circumference equivalent to the distance a geared bike will travel with one turn of the cranks and the chosen gear ratio, thus, riding a high gear ratio such as 53x12T is equivalent to pushing a wheel with a diameter of 119 inches. In contrast, a low gear ratio like 39x25T is equivalent to a 42-inch wheel. Nash, my son, and I had a great time watching these ladies ride for 45 minutes and then a final 5 laps to determine 1st – 3rd place. The top 4 women split $12k . Good times were had by all.
