The beneficial characteristic of speed glue is the increased output it has over the following: sensation, sound, spin and speed. With the new Nimbus Sound, Tibhar has, thanks to the SPI technology, accentuated the sensation and sound, by using a very light sponge. This rubber provides the best blend between spin and sound and offers the player extraordinary playing flexibility. Thanks to the SPI technology the speed glue effect is now naturally incorporated within the rubber so therefore speedglue is not necessary.
