SD CNC 6061 Chainring (4 Bolt) / Black / 50T

Highlights

  • Four bolt pattern
  • CNC machined for accuracy
  • 6061 aluminium
  • 41 up to 50 tooth

Description

SD's chainring is CNC machined from 6061 aluminium and uses the four bolt pattern, so it bolts onto a standard four bolt BMX crank spider.

Sizes run from 41 tooth right up to 50 tooth, so you can gear it down for street or up for the gate. Machining the ring keeps the teeth true, so the chain sits square and drives cleanly.

Features
  • Four bolt pattern. It mounts to a standard four bolt BMX crank spider, so it swaps straight in on most cranks that use bolts rather than a spline.
  • CNC machined for accuracy. The ring is machined rather than stamped, so it runs straight and the chain tracks without wobble.
  • 6061 aluminium. Alloy keeps the ring light where a steel one would add weight out at the crank.
  • 41 up to 50 tooth. The size range lets you dial in your gearing, from a small ratio for street to a big ring for racing.
