Lube Rock N Roll Extreme 40Z RNREA DURABLE LUBRICANT, PERFECT FOR MOUNTAIN BIKES OR RIDING ON WET ROADS. Features: Shake well and apply a stream of lube to the chain at the cassette. Do not drip the lube on like you would oil. This is not oil! Get the chain really wet, as this product cleans and lubes all in one. Freewheel the chain backwards for about 5 seconds, no less. Wipe off all the excess lube, ensuring the chain is as clean as possible. That's it, go ride!
