The 77designz – absoluteBLACK 1X OVAL GUIDE™ is fully optimized to work with oval chainrings. It is the only chain guide on the market that was developed purely for securing the chain in any position of the Oval chainring. No other chain guide is capable of securing the oval chainring so well.
The unique cooperation of absoluteBLACK (oval chainring expert) and 77designz (smart, ultralight chain guides manufacturer), resulted with entirely new product that is incredibly light, mounts in no time, secures the oval chainring at any position of the pedal and can be opened by hand if there is a need of chain removal.
