Sinclair C5 Chain Tensioner Mod

thingiverse

The Simple Fix to Prevent the Sinclair C5 Chain from Falling Off. To stop the chain from falling off the tensioner, start by removing the bolt holding it in place. Next, insert one of these custom-made pieces on either side of the jockey wheel and push the bolt back through. Once done, reassemble everything as it was originally. For added security, use a cable tie at the top to keep this new component in position. Another cable tie should be used at the bottom to prevent the chain from jumping off. When printing these replacement parts, consider using PETG filament for optimal strength and flexibility. PLA might not hold up well under stress and could break easily.
