7000 Series T-6 CNC Machined aluminum plate transformed into a ring of beauty! Like Crupi's 5-bolt gears, these are machined (not stamped). The 7000 series aluminum is more expensive but it makes a stronger and stiffer gear. This along with slightly thicker material makes them super strong and ready to take whatever the strongest riders of the world can dish out!
