Hi,
Rebuilding an old Olmo, with a 6 speed Super Record.
I bought a NOS Sachs-Sedis “Grand Tourisme” 3/32 chain which I shortened to the appropriate length and installed.
It does this (see video). To summarize: the chain rotates freely around the cog, but periodically the teeth of the cogs don’t properly engage with the chain (for a split second), before it slips back in place.
How do so fix this?
