Fenwicks Stealth Road Lube 100ml



Superb all-conditions road lube that not only lasts but stays clean

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.

By Jove! Two hundred miles on one dose of Fenwicks Stealth Road Bike lube and I'm starting to appreciate what all the fuss is about. It's like none I've used before.

It's probably closest to a light ceramic in terms of serenity and durability but considerably cleaner. That said, getting the best from it requires methodical application.

Fenwicks are justly coy about the exact composition, talking in terms of heightened lubricity that supposedly reduces heat generation, wear and cushioning additives. Reading between the lines, this sounds like Boron Nitride-an extremely powerful, temperature resistant additive, commonly found in high stress manufacturing contexts. Synthetic blends can turn syrupy in cold storage and the Stealth's no exception - easily cured by standing in warm water for sixty seconds or so.

Application is a little more involved than the tip and scoot off, requiring that your chains are super sterile first. Give the stealth a quick shake, unscrew the cap and drop a tiny amount of the silvery prep on every link, holding a rag beneath to collect any overspill. Rotate the cranks for thirty seconds, allowing it to invade the chain's most intimate regions before leaving an hour or so to cure.

Unlike ceramics, there's no need for a second coat and doing so results in a very sticky mess sixty miles hence. Flicking the pedals rewards with a smooth, silence associated with wet blends but without the stodginess. Taking to the road, it doesn't feel markedly different from competitor brands. Shifts aren't quite as frisky as the waxy, emulsion types but a marked improvement over ceramics.

The biggest talking point is its staying power and cleanliness. Riding for several hours in heavy rain and along flooded roads hasn't made any impression whatsoever - more than can be said of a companions' choice of synthetic motor oil, which had begun the metal on metal symphony in a matter of hours (it's worth noting that motor oils contain swarf flushing detergents designed to be renewed under pressure from the oil pump, thus don't work well on bicycle chains).

It assumes a clean but clearly evident film, resisting dung, silt, mud and all the ruinously gritty stuff without contaminating fingers or clothing when doing any maintenance.

The best chain lube I've ever used was Duckhams Chain Guard. This came in something like a cake tin, which had to be heated on the hob to melt the lube, and the clean chain was then immersed. They don't make it anymore, probably on the advice of the Fire Bigade, but the way the warm lube penetrated (stop sniggering at the back), and clung to the chain after it cooled down, was amazing. Is there anything similar available nowadays?

I used to use Filtrate Graphite on the motorbike and doing so on a new chain would double it's lifespan, maybe there was a conspiracy from the chain manufacturers to get rid of it

How often would you need to clean the chain; before re,applying the lube?

How does this compare to Purple Extreme?

I've run this on the last couple of occasions partly to see if it would quieten down my Wippermann chain which is quite noisy - it did.

I've previously lubed chains just by wiping down and applying more dry lube but this seems to need a thorough clean each time. Any advice on whether to clean each time or is it possible to top up occasionally?

I've been using this during the year and have been really impressed. I clean my chain (with a Park Tool cleaning device) before re-application as it definitely works best on a clean chain.
