Race Face Narrow Wide Chainring

The Race Face Narrow Wide Chainrings can work with any four-bolt 64mm bolt circle diameter spider on a bike built for any off-road discipline. They have been designed to work with 9-, 10-, 11- and 12-speed drivetrains. They can be used alone or in conjunction with bash guards. It’s one versatile chainring. The narrow-wide alternating profile is a proven way to keep the chain on a 1x crankset without needing guides to keep the chain on track. Race Face improved the breed by machining the ring into an I-beam shape and leaving a 4mm wide plate so as to be as stiff as possible.7075-T6 aluminum alloy is the metal of choice for it’s high strength, low weight, and proven longevity. The rings range from 30-38 teeth in two-tooth increments.
