"Bill Mould’s “The Bicycle Wheel: Physics and Engineering” video course answers just about every question I have ever come up with about bicycle wheels. Bill has surely done the most thorough research into the variables that makes a bicycle wheel work of anyone in history. The mystery of why a super-stiff wheel with a very deep carbon rim will rub the brake pads when sprinting out of the saddle is explained in here. Like everything else in Bill’s digital wheel course, it is tested experimentally in the lab, and the results are explained with very clear graphic illustrations and photos. This course is a must for anyone wanting to be a wheel guru; all of the answers are here!"
