Wet weather and long distances expose the limitations of most chain lubes. Standard formulas wash off in rain, leaving you with a squeaking drivetrain halfway through a ride, while heavy wet lubes attract so much grit that your chain becomes a grinding paste dispenser. Progold developed the Extreme Chain Lube to address this gap, building on their proven ProLink formula with more persistent chemical carriers that maintain their bond to metal surfaces through conditions that would strip lighter lubes clean.

The formula uses Progold's MFR (Metal Friction Reducer) technology, which bonds directly to metal surfaces at the molecular level rather than sitting on top as a film. This bonding creates a durable lubrication layer that resists washing off in rain, slush, or stream crossings while still shedding water from the chain's exterior. The Extreme version uses a slightly heavier base than standard ProLink, increasing the MFR's ability to remain in place during extended high-stress use without becoming noticeably thicker in application or attracting significantly more dirt.

Unlike wax-based or heavy wet lubes, the Extreme formula contains no solids like Teflon, wax, molybdenum, graphite, or plastic particles. This means the lube won't build up into a tacky residue that accumulates grit over time. Riders report getting 150-200 miles between applications in challenging winter road conditions, and 30+ miles in muddy cyclocross racing before performance degrades noticeably. The thin-bodied consistency penetrates into the chain's bushing-to-plate interface where lubrication matters most, rather than coating only external surfaces.... Read More
