Muc-Off Ludicrous AF
The famous maker of all things related to the cleaning of bikes has launched the world’s fastest ever bike chain lube.
Ludicrous AF is claimed to offer 18% less resistance than the next best chain lube and as such is used in the Pro Peloton by Ineos Grenadiers and EF Education NIPPO.
Q: What makes it faster?
A: It offers less resistance by creating a fluid sheer plane where the long-lasting synthetic polymer reacts to the chain surface.
Q: How much faster
A: Perhaps a poor chain could cost you 5w in a super worst-case scenario so you might think it would save you 1w. Although a new chain could perhaps save you 4w in that scenario!
A bargain at £50 for a 50ml bottle.

My favourite kit and nutrition
- Maurten — the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
- Garmin 90-degree charging adapter — the small adapter that keeps your charging cable tidy at the stem. Essential for race day.
- Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session.
- Ravemen FR300 — front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters.
- Garmin Varia RTL515 — radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch.
- Stryd — the footpod that brings running power to your Garmin. The single most useful running upgrade I have made.
- Favero Assioma Pro RS2 — the power meter pedals most serious cyclists end up choosing. Accurate, easy to move between bikes.
