The Wolf Tooth Direct Mount Chainring for Shimano cranks with 12-speed HyperGlide+ chain not only shines with its aesthetic, ultra-lightweight design: thanks to the patented Narrow-Wide design, it achieves the ideal single-chainring setup, preventing the chain from dropping off the chainring. With this setup, your dream of the perfect drivetrain comes true! The winter months in Minneapolis, the production site of the US company, are tough, and accordingly, this Wolf Tooth Direct Mount Chainring is designed to be robust and high-performing. It is optimized for trouble-free use with 12-speed HyperGlide+ chains. After all, the motto is: We want to ride – not fiddle with the chain! According to the quality standards of the Wolf Tooth brand, this product scores with its unmatched design, absolute reliability, and high durability. The patented Drop-Stop Wide-Narrow tooth profile ensures that the chain runs securely in your single setup. At the same time, it prevents mud and dirt from getting stuck – the result is maximum efficiency! To achieve the highest functionality even under extreme conditions, combined use with a clutch derailleur (with derailleur damping) is recommended. • Application area: MTB • Compatibility: Shimano XTR M9100 and Shimano 12-speed HyperGlide+ chains • Front gears: 1-speed • Rear gears: 9-speed • Chainrings • Mounting / number of holes: Direct mount.
