Machined from strong 7075 T6 aluminum, the Zen is one ultra-round, super-rigid ring.
These mighty chainrings also feature the SSGN super smooth tooth profile, which means the tooth valleys are rounder and the side tooth profile is smoother than standard Sugino 75 rings. This process helps greatly reduce chain noise and improves ring/chain engagement and wear.
Silver 44-55t are NJS stamped.
Zen chainrings 55t and larger are not returnable. Please do the necessary measuring to make sure your frame has clearance before ordering.
