Abstract
The frame of a racing type bicycle is made very rigid to increase the power transmission efficiency and to improve the handling and riding characteristics. The preferred configuration uses large diameter tubing in aluminum alloy to achieve a lighter, stronger and much more rigid frame than prior art.
