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.
Frame/Fork WeightA 56cm frame weighs 5lbs. on the dot as sold, including all the bolts, dropout adjusters, cable adjusters, front derailer roller, and seat clamp. The fork with bolts and 350mm uncut steerer is 2lb. 10oz. Add or subtract a couple ounces for each larger or smaller frame size to estimate the weight of other sizes.
