Vortex 520 Rear Sprockets (Marvic, Galespeed Wheels)


Marvic and Galespeed aftermarket wheels use a different bolt pattern from OEM for rear sprockets.  6 bolts, 10.5mm diameter, on a 100mm bolt circle with 80mm center hub diameter.  Use these sprockets instead.


Vortex Racing has been manufacturing championship winning sprockets since 1995.  Their race proven CNC machined aluminum sprockets are made from the highest strength 7075 aircraft grade aluminum and have become the industry standard for light weight, high strength sprockets.

Vortex rear sprockets are available in 7075 high strength aircraft grade aluminum.  Aluminum sprockets are lighter weight and preferred when performance counts.  Read here about improving handling and horsepower by removing unsprung rotating mass from a motorcycle.

Aluminum sprockets are available with black type 2 anodize.
