Rex Black Diamond Wax Chain Lube Review

Rex Black Diamond claims to be one of the longest lasting, and fastest chain lubricants ever. It may also be one of the most difficult to get - with very few retailers stocking it. It is certainly one of the most expensive, at over £1 per ml (£35 for 30ml). After trying many other chain lubricants that claim to be fast, and long lasting I wanted to see how it performs both on and off-road. General riding conditions were typical British Autumn and early Winter weather. Temperatures below zero, up to low double figure and plenty of rain and mud. To give a good comparison, the chain lubricants that I typically use, and have used: Preferred race option - Immersion wax with Molten Speed Wax Preferred standard option - Squirt Why wax? A good wax based chain lube will significantly improve drivetrain lifespan over using a more traditional oil-based chain lube. Others tried: Muc-Off AF, Ceramicspeed UFO Drip V2, Smoove, Chain-L, Morgan Blue wax + a huge list of oil based options that sit on the shelf, never to be touched again.
