Safe for carbon

The Gum Gum has all the same features of a standard starnut expander but much much lighter and perfectly safe for high end carbon forks. It will fit Inner Diameter steerers that have the measurement of 24mm to 25.5mm. It uses a special NBR rubber (black) that compresses the silicone ring that grips the steerer tube allowing you to preload the headset bearings to the manufacturers specs. Gum Gum can be removed and re-used over and over but at 9grams it is a great option for all your bikes.
