This high-quality chainring features a hard-wearing steel construction, which allows it to withstand all of the speed and torque that's associated with long days on the trails. Box has also put this model through a forging process for extra durability and a CNC-machining process to remove any excess material while still maintaining strength. Coming complete with an ED Black Protection coating, it provides additional protection against corrosion when exploring the mountains in all-weather conditions.
The Box Four Wide/Narrow chainring completes the package for the 1x8 system. It is the first 8 speed specific chainring designed to optimize chain retention when using 8 speed chains. The tooth profile and thicknesses are tailored to match the inside geometry of the unique Box Four chain.
