Gear oil £6.49 yourlocalmotorfactor »

The benefit of lubing O-ring and X-ring chains may be outweighed by wear caused by road dust that gets stuck to the lubricant. I avoid super gloopy lubes because of the grinding paste they create, but apply lube sparingly to the inside edges of the plates of a hot chain to provide some benefit to the rollers. I’m working through a collection of lube I’ve been given, but if I had to buy my own I’d use heavy gear oil, applied with a brush after a decent ride, though most of it will be flung off on the first turn of the wheel.
