It has never been easier to convert your bar which was used for IHC compression and now make it SCS-compatible. Use this adaptor in your standard (inner diameter 28mm) scooter bar with a slit to makes the bar SCS-compatible. Note: Normally you cannot use a bar with a slit to your SCS-system, but with this adaptor you eliminate the squeezing function of the slit, this way the bars will be SCS-ready. This adaptor fits bars with an inner diameter of 28mm. Bars with an inner diameter of 28mm are steel and aluminium bars initially made for IHC compression.
