Review on 🔩 Truvativ Chainring Bolt Kit 5 Arm: Enhance Cycling Performance with Secure Fastening by Alberto Brewster

They are useless if you are replacing a 3 speed gearbox with a single pinion. The chainring must be adjusted to the center ring home position to keep the chain in the correct alignment, but in this configuration the nuts are too long and protrude through the chainring and crank making it impossible to tighten the bolt. They come with shims but are designed to correct the chainline when converting a 2x drivetrain to a single sprocket, not to compensate for long nuts.
