Crupi 4-Bolt Chainring
7000 Series T-6 CNC Machined aluminum plate transformed into a ring of beauty! Like Crupi's original 5-bolt gears, these are machined. The 7000 series aluminum is more expensive but it makes a stronger and stiffer gear. This along with a slightly thicker gear makes them super strong and ready to take whatever the Elite riders of the world can dish out!
