Frame Saver?All frames are coated inside and out with a corrosion resistant black electrophoretic deposition (BED) coating. A frame saver spray isn’t necessary, but if you are going to ride in a wet area, a shot of Frame Saver™ or Boeshield® couldn’t hurt, especially in the lower part of the frame were moisture could collect.
