Brunox Top Kett Chain Oil



Superb chain lube at a superb price too

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

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 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.

I've been told by Brunox that only the pump version has been discontinued. The same lube is available in a 100ml aerosol. I've used that & mostly agree with the test above. It's not absolutely the best I've used but almost. I like good wax lube as the chain stays even cleaner & some last for as long or longer between applications. This stuff is cheaper though. Also like Green-Oil, they do some great stuff.

Just spoke to the mechanic at the very fine York Cycleworks on 01904 626664 who says they stock Brunox although it doesn't appear to be listed on their webshop.

None at; have now delisted it; CRC have also delisted it and rosebikes charge £5.05 for shipping so not cheap.

£5 shipping? Ouch!  13

Hmmm, it's a bit odd that Brunox would send us a load of stuff to test if it's not easily available. I'll see if we can find out what's going on...  39

Brunox do a whole load of stuff but I've only tested this one.

These guys have it -

so do

This doesn't seem to be available anymore - is it the same or similar stuff as any of the other lubes on the Brunox website?
