Leatt ReaFlex 6.0 Grips - Peanut - Single Lock On Grips - 29mm - Thin Needs Images This tool provides enough leverageThe core of these grips is infused with Leatts energy absorbing non newtonian ReaFlex gel, noticeably reducing vibrations.

This means that ReaFlex is especially efficient at dampening micro vibrations. The variable diameter taper profile with more material on the outer edge, where more contact is made, reduces hand pressure
