FX-S: high grip PRO upper rubber, flexible medium sponge, medium-high speed and maximum spin.
FX-S is the 'little brother' of the EL-S.
The FX-S has the enormous spin values of MX-S and the power of the MX-P combined with a newly designed rubber surface.
The sponge of the FX-S is softer than the sponge of the EL-S, so that the FX-S in combination with a personalized pimple geometry is more elastic which generates 'Flexible Spin'.
The FX-S is much softer than MX-P and MX-S, but slightly harder than the FX-P. FX-S significantly distinguishes itself from the medium rubbers EL-P and EL-S.
