Narrow Wide tooth profiling ensures ultimate chain retention
These chainrings are a game changer for single-ring drivetrains! These ZTTO Single rings now feature performance-enhancing chain retention technology, allowing them for most riders to be used without a chainguide! The secret are alternating fat/skinny teeth to fit more closely into the narrow and wide plate spacing of a normal chain, grabbing the chain and holding it more securely even without the use of a clutched derailleur.
