This is an excellent book - a masterpiece of clear writing and a delight to read.
If you have ideas of inventing a new way of spoking a wheel that has never been done before, the author suggests not bothering, as it will already have been tried by someone. Instead, he suggests letting your contribution be in building wheels of excellent quality.
Since buying my first copy of the book (later replaced after I lost the first copy), I have built maybe six wheels by following the instructions. They varied from a front wheel for an old Moulton bike with a front hub brake (with spokes only a few inches long) to 27-inch wheels for a vintage Carlton racer. In every case, I simply followed the step-by-step instructions - result, a perfect wheel, every time.
For anyone wanting to build bicycle wheels, or who simply wants to understand how they work, I recommend Jobst Brandt's book without reservation.
