Sugino BIG Zen chainring (59-66t)
For all you brutal quad-busting beasts out there, Sugino now makes their legendary Zen rings in HUGE sizes.
Machined from stiff 7075 T6 aluminum, ultra-round and super-rigid, these chainrings also feature the SSGN super smooth tooth profile, which helps to greatly reduce chain noise and improves ring/chain engagement and wear.
