That it did about as badly as the Purple Extreme?
I'd only use it in an emergency, honest!
And before anyone takes exception at me calling cyclists "credulous" I'd like to point out that I have a toolbox full of expensive bike lubricants too!
I'm guessing that if you clean and lube your chain every ride then it doesn't matter that a lube doesn't have a long life. I am not one of these people because I am lazy, I don't even pump my tyres every ride. Sometimes I even forget the 21 point safety check!
