Respuesta :
Start with the saddle low, then try raising the saddle higher, and then slide the saddle forward.
The answer is C:
1. Start with the saddle low: "You may commence with the saddle a little low."
2. Then try raising the saddle higher: "Raise the saddle until high enough to cause a complete straightening out of the knee and a little dropping of the toes when the the pedals are at the lowest point."
3. And then slide the saddle forward: "The peak of the saddle should be a little forward of the crank shaft."
