Crupi 4-Bolt Chain Ring

  • Sale
  • Regular Price $49.99 USD


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!

  • Chain fit = 3/32"
  • Available in sizes 36t through 46t
  • Weight = 3.10oz (43t)
