For all you brutal quad-busting beasts out there, Sugino now makes their legendary Zen rings in HUGE sizes.

Machined from strong 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.

Big Zen chainrings are not returnable under any circumstance. Please do the necessary measuring to make sure your frame has clearance before ordering.
