The Rocket Attack Dome Center Cap is the center cap that is included with the purchase of the Rocket Track and Touring Series Rocket Attack Wheels.  If you simply need a replacement for a lost or damaged center cap, this is the cap you need.  We also now have an optional Flat Center Cap, you can purchase.  See our Wheel Accessories page.  Note: If you are ordering the flat center cap, first confirm that you do not have a spindle height issue.  The Dome Center Cap shown here allows for an additional 1" clearance underneath the center cap.
