Brunox Top Kett is a Swiss made lube and it's about as good as it gets. Shame about the pump dispenser though.
As a road.cc tester I'm used to recieving reproachful e-mails from the testing database reminding me that my review for product X is overdue. I've lost count of how many e-mails I've had regarding the Top Kett lube but that's tough, since I've only had to apply it twice since I first took delivery. Which was back in August.
The omens weren't good, it's a thin spray-on lube and I don't have a high opinion of thin lubes. Previous experience said that it would be the kind of delicate rubbish that evaporated after a harsh look, never mind a muddy hundred miler. I was wrong.
Applying the stuff isn't easy. It comes in a spray can, but it's the pump action kind so keeping the can levelled at your chain while pumping the nozzle is a trying experience best undertaken with a thick wad of kitchen roll behind the chain. The thin white lube covers everything really easily, so your aim doesn't have to be spot on. It's not the most efficient method of application and a pressurised spray can would make life much easier.
Brunox don't give much away but they make lube and anti-corrosion products for more intense applications than just bike chains and whatever goes into the Top Kett lube, it's serious stuff. Having squirted it onto a clean chain I waited a whole 520 miles before chickening out and applying some more. Usually what happens when a lube stops working is that your chain starts to squeak, rust spots appear and shifting performance drops off. None of that happened, I just got cold feet that a thin lube could last so long. When it came to cleaning off the first application my chain was remarkably free from grot and filth. You would be forgiven for expecting this from a dry lube, after all that's what they are famous for. What they aren't renowned for is longevity. Getting both from one lube is a real bonus. The second application survived some pretty foul weather, the Dartmoor Devil audax (muddy, grim) and is just running dry after over 300 miles. That's really quite remarkable.
If you can cope with the faffy delivery method then this is a cracking lube for all conditions. Despite my initial preconceptions I'm impressed.
The indisputable leader of the gang.
He's the boss, he's a pip, he's the championship.

He's the most tip top,
