Description

The Renthal 439--520-12GP is a front chainwheel designed for optimal strength and hardness. It features a specially developed nickel-chrome-molybdenum steel construction that is case-hardened and core-refined. The grooved design includes cut-outs at the bottom of each tooth to allow mud to escape, preventing trapped debris from creating tension on the chain and reducing accelerated wear.
