A very clean chain lube that works, lasts and never lets you down. When the going gets tough, this is the stuff.

Application instructions
. 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, this stuff cleans and lubes all in one.
. freewheel the chain backwards for about 5 seconds...no less.
. wipe off all the excess lube...all of it, wipe the chain as clean as it will get.
