Green Oil is a British company that makes chain lube that doesn't actively destroy the earth. Most bio lubes are green washing. Some have friggin' teflon in them, which negates any biodegradable claims. Green oil is plant based, 100% biodegradable, and works as well as Finish Line Wet Lube. Go ahead and look up reviews on Pink Bike, or Road.cc. Long term tests show that this chain oil is not only eco friendly but also just a good lube.
We dig this small 'tour' size bottle, which is a perfect amount (30ml) to bring with you on a week long tour or a 3 day really wet tour.
With any wet lube, lube the chain so the rollers are covered, then wipe off any excess after you let the lube sink in.
Nutshell: You need a wet lube, get this one.
