Composite rear 51T Fast pulley for use on the Serpent 960, 950R, 950 and Vector.
Introducing the latest performance enhancing optional for the Serpent 960. A replacement for the standard 51T rear pulley, this composite part features a new disc like appearance. Testing has shown that this new profile adds approximately a 3kmh increase in top speed. This is possible due to the pulley’s new profile that is devoid of ribs or any other wind resistant features, allowing the part to rotate unrestricted.
