Muc-Off Bio Dry Lube is a liquid chain lubricant designed for bikes used mainly in dry weather. Its plant-based oil formulation is claimed biodegradable and PTFE-free.

It’s applied directly to the chain rollers using a fine-tipped applicator, handy for precise dosing and limiting excess. Despite the plant wax in the mix, it remains an oil-based lube rather than a true liquid wax.

Useful features

• Chain lube for dry conditions
• Plant-based oil formulation
• Biodegradable and PTFE-free
• Fine applicator for roller-by-roller application
• UV function to verify coverage with a compatible light

This lube is best suited to road riding or dry terrain, with careful application and a wipe-down to remove any excess after application.

In testing, Bio Dry Lube ran particularly quietly and felt good on a road drivetrain. It held up well in the dry, but quickly showed its limits after a prolonged ride in the rain.

Muc-Off All Weather Lube is a synthetic oil designed for changeable conditions. Its hydrophobic formulation aims for broader versatility, on road and off-road alike.

Its texture is wetter and greasier than a dry lube. Application therefore calls for careful control of how much you use, followed by wiping away the excess before riding to avoid chain fling.

Useful features

• Chain lube for variable conditions
• Synthetic, hydrophobic formulation
• For road and off-road use
• Fluid, wet texture
• UV function to check even coverage with a compatible light

This lube suits riders seeking a more versatile option than a strictly dry lube, with particular attention paid to dosing.

In the dry, All Weather Lube kept the drivetrain running smoothly and easy to look after. The test didn’t, however, let us properly assess its behaviour in the rain due to a lack of sufficiently wet conditions.

Muc-Off Bio Wet Lube is a chain lubricant designed for wet and muddy conditions. Its plant-based oil formulation is claimed biodegradable and intended to stay in place better as the weather deteriorates.

Its texture is greasier and slightly more viscous than a do-it-all lube. Precise roller-by-roller application and careful wiping of any surplus are still necessary to keep the drivetrain clean.

Useful features

• Chain lube for wet and muddy conditions
• Plant-based oil formulation
• Biodegradable
• Clingier texture around the links
• UV function to verify coverage with a compatible light

This lube is aimed at winter, wet or more demanding rides, when the priority is to keep the chain lubricated despite water and spray.

Tested in hot, dry conditions, Bio Wet Lube kept the drivetrain running smoothly, without excessive build-up. Its real behaviour in the rain remains to be confirmed in the conditions for which it is intended.
