Basically we recommend to use our CORE Sensor Bar at the standard width of 52cm with any kitesize and at any model. If you feel like that the smaller kitesizes turn too fast you can use the smaller width of 46cm. Which could be useful in high winds for kites of 7 meters size and smaller.
If you're into freestyling and use the CORE Impact or CORE GTS the CORE Sensor Wake Bar with 42cm width might be the best choice, because it avoids too fast turning.
And if you're into Kitefoiling and use the CORE Xlite, our CORE Sensor Foil Bars with 45cm width are recommended.
