There's something fishy in Whitewater. These look like regular track? bikes with a longer fork to keep the top tube parallel to the ground and the pedals from being to close to the track. If you just pull a 700 wheel out and put a 24" into a regular track bike you'll drop the front end at least an inch. As you see the head tube on my motor pace machine is very long to compensate. Not so on the English bikes. I wonder if the English builders, clever as they were didn't make a hybrid type fork to use in human pace races at the time, like they did at the turn of the century. Note the chainwheel size is also standard size, as speeds would not have been much more than about 45 mph, top end compared to around 65 in an actual motor pace event. 10 mile pacing is quite an endurance speed event, not for the faint of heart. We need some English illumination here, on racing not done today. It's similar to Derny Racing, and much longer than Keirin. At higher average speeds the reverse fork and the resulting trail gives a slower less erratic control ability. This was figured out around the turn of the century and gave a greater margin of safety to the riders in addition to better wind protection. Nice bikes and great racing, wish the photo was a little more detail clear so we could study the bikes somewhat better. Ted Ernst Palos Verdes Estates, CA
