Chrome or stainless steel center caps are great for hiding the ugly bolts and nuts holding your wheel to the axle. They can also protect specialized axles, like hubdometers. The diversity of styles available for hubcaps has increased in the past several years. You can now jazz up your axles with "spinner" style knock-offs that bolt to your hubcap, or by using a stylized hubcap like the pinwheel. The possibilities for customizing your wheel look are endless, and easily tailored to your personal style or budget.
