That plastic accordion-like tube that you wrapped onto your chain to keep it clean? You had to cut a thin slit into it to let the chainring cleanly pull the chain. It came in different colors to match your ride. It came out in the early to mid 80's (yes, I've been riding for a while). Does anyone remember what it was called?
