Utilizing "Narrow-Wide" technology, these chainrings are designed with teeth specific to the male and female parts of your chain, which guarantees maximum chain retention in the harshest of conditions. Perfect for your 1x9, 1x10 and 1x11 drivetrain, the narrow wide chainrings are nearly universal for any MTB application. The long wearing 7075 aluminum is durable and impact resistance, reducing the chance of bent or broken teeth.
Narrow-Wide chainring's concept is based on an US patent back in 1979 and originally intended for agriculture use. Many companies use it on MTB due to its great chain retention function. In order to stand out from the market, UFOR develops the unique design on the surface contour and has the design patent.
