At road.cc 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 road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
Fenwick's Stealth Road Bike lube is a phenomenally clean-running, long-lasting synthetic lubricant and probably my favourite of all the many space age preps I've tested to date. At £9.99 it's highly recommended, and gives comparably sophisticated chain lubes a seriously good run for our hard earned, although methodical preparation/curing times won't suit everyone.
Fenwick's gives little away in terms of composition, talking in terms of heightened lubricity, cushioning additives and other wondrous friction-reducing compounds. These supposedly maximise efficiency while minimising wear.
Synthetic blends can turn bashful in cold storage and Stealth is no exception – easily cured by popping the container in a bowl of warm water for a minute or so. This version has shunned the pipette dispenser in favour of the twist spout, which makes application that little bit simpler.
Get recipient chains surgically clean, shake the bottle and then apply the metallic grey fluid to every link, holding some rag beneath to catch any overspill.
Curing times vary. Fenwick's says it can be used wet but this puts a dent in staying prowess, so it's worth following instructions to the letter. Having used previous versions in the long term, I'm inclined to suggest an hour's curing time is right for spring/summer, but bargain for three to four during the dark, colder months.
Once dry, it's virtually invisible, so don't be tempted to add a subsequent coat or it will turn into a gungy mess within the first 60 miles or so. Ensure every link is fed, mind; my Univega's heavy duty chain showed signs of the dreaded red freckling around its inner plates after being subjected to 150 miles commuting along waterlogged roads.
Otherwise, even subjected to these harsh, slimy contexts, chains, cassettes, derailleurs and rings remain remarkably clean and to the tune of approximately 300 miles per application – 500-plus during temperate and relatively dry autumn months.
Sure, some stout wet lubes will give Stealth stiff competition in this respect but they tend to demand weekly purges of grit and other ruinous contaminants. Like these, Stealth also works well on cleat mechanisms and doubles as a nifty grease substitute for fasteners.
Responsiveness is comparable with other high tech ceramics and seems less inclined to migrate to the outer links on highly polished electroplated and stainless steel chains.
For riders seeking a really clean, long-lasting lubricant, Stealth should be high on the list.

How to use Fenwicks Stealth Road Lube
The heightened lubricity reduces fatigue, heat generation and stretch. Aided by specific cushioning additives, the chain delivers an extremely quiet ride. Corrosion protection is incorporated into the unique air-drying formula.
Shake well. For best results apply to a clean chain.
Step 1: Using pipette apply a drop of lube to each link.
Step 2: Rotate chain for 20 sec.
Step 3: If required, wipe off excess with a clean dry cloth.
Step 4: For best results allow 3 - 4 hrs to cure, can also be used whilst still wet (although the lube won't last as long)
Straightforward and not overly messy to apply.
Very good for a lube so clean-running and long-lived.
