Bicycle wheel rims meant for use with disc brakes or hub brakes sometimes lack this surface. The Westwood pattern rim was one of the first rim designs, and rod-actuated brakes, which press against the inside surface of the rim were designed for this rim. These rims cannot be used with caliper rim brakes. The cross-section of a rim can have a wide range of geometry, each optimized for particular performance goals. Aerodynamics, mass and inertia, stiffness, durability, tubeless tire compatibility, brake compatibility, and cost are all considerations. If the part of the cross-section of the rim is hollow where the spokes attached,
The Bicycle Wheel The Bicycle Wheel The Bicycle Wheel is a treatise on wheelbuilding by Jobst Brandt. "The Bicycle Wheel" is an educational book that explains the structural theory of a wire wheel, and teaches the practical methodology of building bicycle wheels. The book is made up of three parts. Part one, 'Theory of the Spoked Wheel', examines how a wire wheel supports various loads, what causes wheel failure, what aspects of a wheel confer strength and durability, discusses each of the individual components that make up a spoked wheel, and examines wheel design. Part two, 'Building and Repairing Wheels', explains how to
