B'Twin Teflon Aerosol Lubricant is a 150ml pannier-friendly general purpose mix that works a treat on the usual suspects: cleats, mechanisms, pivot points, cables and recessed fasteners. It's also produced on these shores and is very similar to Weldtite's TF2 spray tested by yours truly last year.
Yes, we have what appears to be another blend of mineral oil and PTFE additives powered by solvents and, you guessed it, propane! Shaken and applied from 30cm, the super-invasive ingredients reach and cure within 30 seconds, leaving behind a rich honey-coloured, super-slippery surface.
Unusually, there's no dinky little plug-in straw for precise deployment, although experimenting with other brands' suggests they'll fit. Either way, keep offcuts of card handy when tackling exposed cable runs to avoid messy overspray.
Aside from attracting grimy patinas, these mixtures also soften expensive polymer waxes and similar protectants. Old as the hills, they're not particularly kind to composites either, so minimise contact with the wonder weave, unsealed stickers, suspension and so on.
Generally speaking, traditional freewheels prefer a few drops of liquid refreshment but this one has kept old fashioned six and contemporary single-speed mechanisms, cantilever/V-brake posts and locks sweet for several wet weeks. It also doubles as a convenient grease substitute on cleats, which are largely ignored until wear forces replacement.
A monthly 'while I think of it' shot should keep those little Allen screws mobile. Combined with a torx bit, I've successfully rescued some dreadfully weathered examples that were painfully close to seizure.
Low friction characteristics mimic that of B'Twin's chain and derailleur oil, although this appears a stouter brew. It's easily on par with relatively pricey spray'n'go commuter fare; I've returned 175 miles per single stage, double coat helping in comparable, fair weather contexts.
Talking of mobile, I've found the 150ml version a brilliant pannier companion, enabling instant, on the spot top-ups. Well, almost... Stick to water displacers/maintenance sprays when coaxing blinkies back from the dead '' this seems to block rather than boost electrical connectivity.
Bottom line, it's an old fashioned, long lasting yet strangely versatile mix that does most jobs surprisingly well.
Another very capable, long lasting, friction busting spray lube

Size tested: Teflon Aerosol Lubricant, 150ml
Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
"long-lasting lubrication for your drive train
"Teflon lubricant for greater efficiency"
Good, clean running summer weight chain lube that also works extremely well on most metal on metal surfaces.
Tell us some more about the technical aspects of the product?
"DANGER! Extremely flammable aerosol. Pressurised container: may burst if heated. Causes skin irritation. Harmful to aquatic organisms. May cause long-term adverse effects".
PTFE based lubricant spray using solvents and propane.
Generally excellent in all contexts and easily on par with the super-convenient squirt'n'go versions when used on chains. Ironically enough it just has the edge on B'Twin's chain and derailleur oil too.
Clean and convenient but hold some old clean rag beneath the chain to avoid unnecessary mess, use outside/in well ventilated areas and wear latex examination gloves if you suffer from sensitive skin.
Not particularly cheap in comparison with some suspiciously similar formulas, but stays put.
Tell us how the product performed overall when used for its designed purpose
Overall, this is another highly competent general purpose lubricant, although there are much better chain-specific options – B'Twin's simple Teflon-based pour-on variety being a budget conscious case in point.
Tell us what you particularly liked about the product
Keeps metal on metal surfaces really slick and silent. Attracts relatively little dirt.
Tell us what you particularly disliked about the product
Nothing per se but a little pricey given other brands offer 500ml aerosols for the same money.
Did you enjoy using the product? Yes
Would you consider buying the product? Yes but in a larger, 500ml size.
Would you recommend the product to a friend? As a heavy duty general purpose spray, yes but there are better chain-specific options.
