Scooter Bars

Scooter Bars / ICS Star Nut

Back to Glossary Index See all Scooter Bars

Keywords: ICS star nut , star nut

900::ICS Star Nut




To make a standard pro scooter bar work with ICS compression, a star nut is installed. The star nut has a diameter of 1 1/4 inch and is best pressed in with a star nut setting tool. Most star nuts have metric 6mm threads allowing a compression bolt to be screwed in. Most commonly, the star nut is pressed in about 2.5 inches from the bottom of the pro scooter bar’s down tube. Star nuts can easily be damaged or pulled down by over-tightening of the compression bolt. Always make sure your scooter clamp is loose when tightening the ICS compression. Some brands (Ethic, Addict) have “star nuts” welded into the scooter bar. They usually require a special compression bolt and are recommended to be used with a ICS fork from the same brand. Star Nuts do not fit in oversized (HIC) pro scooter bars.

Scooter Bars / Flangeless versus Flanged Grips

925::Flangeless versus Flanged Grips




Grips make holding your pro scooter bar more secure and comfortable. They come in many colors and textures and with- or without flanges (flangeless). Whether you want flanges on your scooter grips is a personal preference. Because flanges sometimes cause blisters on their thumbs we find that most pro scooter riders prefer flangeless grips.

Scooter Bars / Bar End plugs

950::Bar End plugs




Bar End Plugs come with a set of scooter grips. These are usually made of plastic and do not last very long. If you ride without them, and your pro scooter drops, the bar ends will damage and in the case of aluminum bars, “mushroom”. Eventually, your grips will get damaged and/or it becomes difficult to remove. Aluminum bar end plugs will extend the life of your pro scooter bars.

Scooter Compression Systems

Scooter Compression Systems / SCS Fork Steerer Length Recommendation

Back to Glossary Index See all Scooter Compression Systems


999::SCS Fork Steerer Length Recommendation



Pro Scooter Decks from different brands come with different head tube lengths. Scooter Forks from different brands come with different steerer tube lengths. This means that not every fork will fit well on every scooter deck with SCS compression.

We recommend that the fork steerer tube has a minimum length of 1 1/4" and a maximum of 1 3/8” above the headset for 3" SCS.

A minimum of 1 3/4" and maximum of 1 7/8 above the scooter headset for 4" SCS.
