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,
Wonder Wheel Wonder Wheel Wonder Wheel is a tall eccentric Ferris wheel located at Deno's Wonder Wheel Amusement Park, in the Coney Island neighborhood of Brooklyn, New York City, US. Eccentric wheels differ from conventional Ferris wheels in that some of the passenger cars are not fixed directly to the rim of the wheel, but instead slide on rails between the hub and the rim as the wheel rotates. The Wonder Wheel is an official New York City Landmark. "The Wonder Wheel" was designed by Charles Herman as an improvement on G.W.G. Ferris' giant wheel. Built for Herman J. Garms, Sr. between
