This one’s for the speed freaks. Say hello to the world’s fastest race lube – Ludicrous AF. It's pure drivetrain dynamite!

This badass bottle of liquid magic has been in the works with our lab boffins for over three years. The result is a category-leading piece of exceptional science that marries unrivalled speed with sustainability, through cutting-edge research and innovation.

It’s the F1 car of bike lubes – stripped back to the bare essentials. That means no colouring, no fragrance, no additional corrosion inhibitor, just a unique blend of renewable and readily biodegradable ingredients designed to minimise chain friction and wear, whilst maximising performance in all conditions. This all means one thing – RAW SPEED!

With an ultra-viscous formula that makes its way into every contact point of your chain, smoothness and silence is guaranteed. So when you’re chasing the competition you can shift with the confidence that you’re using the best around.

Developed in secret over a number of years by Muc-Off’s in-house R&D Team, tested with INEOS Grenadiers, EF Education-NIPPO, BMC Pro Triathlon, Canyon//SRAM, plus other professional teams and athletes, Ludicrous AF takes drivetrain performance to a whole new level. Perfected throughout the 2020 Grand Tour season, with multiple podiums and overall wins at the last two Giro d’Italias, you simply won’t find a faster lube!

Calling all hardcore roadies, track racers & triathletes, the game just changed




Tested and refined over the last three years by the industry’s leading tribologists, Ludicrous AF has been pro-peloton-approved for taking speed and performance to an entirely new level. Thanks to their state-of-the-art R&D facility, our Muc-Off boffins have created a true masterpiece – an ultra-low-friction, highly durable lube which allows you to go harder and faster for longer than ever before. Basically, it’s fast as f**k!



Developed with INEOS Grenadiers, EF Education-NIPPO and deployed on the Olympic stage, winning 6 gold medals in 2021. Ludicrous AF has been built to take on all conditions at the highest level of racing. Tested during the 2020 season and perfected for 2021, this badass lube has already taken multiple podiums and an overall win at the 2021 Giro d’Italia.


For Ludicrous AF, simplicity is king. It’s all about a few essential ingredients, that are dialled-in to work together in perfect harmony. This is a race lube after all, so it's a pure, stripped back performance focussed bottle of speed. That means no colouring, no fragrance and no additional corrosion inhibitor. Just a unique blend of environmentally friendly raw ingredients designed to minimise chain friction and wear – so you can put some serious power down, mile after mile!


Ludicrous AF changes the game. When applied to a chain, it penetrates chain link scars to create a sheer plane – which means more speed! The molecules in the formula charge up, which helps to accelerate both chain and rider by reducing friction and power loss. The proprietary additives contain synthetic polymers, which are designed for long-distance performance. This means class-leading low levels of wear on chain components, making it super-fast and super-durable. This provides unbeatable performance in both wet and damp or dry and dusty conditions at a range of temperatures. All in all, it hits any other competitor chain lube or wax out of the park


When developing a chain lube for the world’s fastest riders, nothing but the best will do. We formulated Ludicrous AF to be liquid lightning to help our teams and riders win at the highest level. As we know, less friction means more speed and better shifting efficiency, which is what ludicrous AF is all about. The drivetrain is often overlooked in the search for speed, with gains from wheels, tyres and clothing taking the headlines – Ludicrous AF is the lube to make the world sit up and listen!



We work with the top teams in professional cycling and triathlon, providing them with optimised chains that are often the difference between winning and losing. Our motto: Treated chains = performance gains. We receive hundreds of chains from teams around the world. They’re cleaned multiple times using our state-of-the-art Ultrasonic Tanks and specially formulated cleaner, before being dried, and then optimised on our ‘dyno’. We then give them a thorough coating of Ludicrous AF before packaging them up in James Bond-style briefcases and shipping them back to the world’s best, complete with testing data. We’ll soon be making this process available to everyone – more on that in the coming months!



With Ludicrous AF, shifting is smoother than anything else you will have experienced before. With its easy application, you’ll be able to hit every contact point of the chain for a super-smooth ride. The viscous formula reduces chain noise and rattle for stealthy shredding – who doesn’t love a quiet bike? We’ve even gone to a molecular level with our in-house contour white light interferometer, to study how the lube beds-in to the chain, giving you turbo-charged performance.



The Ludicrous AF formula is non-toxic and readily biodegradable, so you can prep your chain ready for racing, guilt-free! In wet conditions or when a bike is being cleaned, naturally, some lube will get washed away. Unlike other competitor lubes and waxes that often contain harmful ingredients like PTFE, Ludicrous AF won’t leave a toxic oily mess that damages the environment. That’s not all, Ludicrous AF will also prolong the life of your chain and even bring it back to life. The lubricant continues to improve with chain run-in due to continued surface improvement at a molecular level, so you can minimise your environmental wastage by using an existing chain, whilst maintaining the same incredible levels of performance.
