Long before GSV-1 and GB 10.7, there was our Trimax Reactive Coverstock, used on the original Vortex and Matrix series. Trimax was the most aggressive coverstock for Ebonite during its time. Compared to today’s coverstock formulations, Trimax created less friction in the oil. Our new Trimax19 maintains aggression at the backend of the lane, but now features a stronger reaction in the oil due to its updated formulation.
