  • CNC machined aluminium
  • Anodised blue finish

Description

A four bolt chainring from Avian, CNC machined from aluminium and finished in anodised blue with laser etched Avian logos. It is available from 36T right through to 50T, so you can set your gearing where you want it.

Cutouts change with the size: 40T and smaller run four cutouts, while 41T and larger run eight. Check your crank takes a four bolt ring before ordering.

Features
  • Four bolt fitment. Made for four bolt cranks, so it swaps straight on if that is the pattern your spider already uses.
  • 36T through to 50T. A wide size range lets you pick the tooth count that suits your gearing rather than settling for what is on the shelf.
  • CNC machined aluminium. Machined from aluminium, so the tooth profile holds its shape under load without adding much weight to the cranks.
  • Anodised blue finish. The blue colour is anodised into the aluminium and the Avian logos are laser etched rather than printed on top.
  • Cutouts scale with size. 40T and smaller carry four cutouts, 41T and larger carry eight, so material is trimmed to suit the size of the ring.

Specifications
  • Bolt pattern: 4 bolt
  • Teeth: 36T to 50T
  • Material: CNC machined aluminium
  • Finish: Anodised blue with laser etched Avian logos
  • Note: 40T and smaller have four cutouts, 41T and larger have eight.
