The image shows a close-up of the rear wheel of a red bicycle. The wheel is attached to the frame of the bike with a silver chainring. The chainring is made up of multiple teeth and is connected to the rear derailleur, which is visible on the right side of the image. The brake lever is also visible in the image, and the chainring appears to be in good condition. The background is blurred, but it seems to be a garage or workshop with other bicycles visible.
