Sugino Zen chainring
Machined of stiff 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.
