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 red finish. The red 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.
