The image shows a close-up of the rear wheel of a bicycle. The focus is on the brake caliper, which is attached to the frame of the bike. The caliper is black and silver in color and has the word "Ridley" written on it in yellow letters. The brake rotor is visible on the right side of the image, and it appears to be made of metal. The background is blurred, but it seems to be a brick sidewalk or pavement.
