CRC 1/12 Double Clamp Left Hub. Due to the tight confines of 1/12th scale racing, left wheel hubs have always had a problem being both lightweight AND balanced. That is now solved with CRC's double clamper. Perfectly true, balanced and lightweight, the hub fits all Xti-based CRC 1/12th cars. It will fit any 1/12th car with the proper spacing on the left side bulkhead.
