B'Twin wet lubricant is designed to resist the worst that winter can hurl at us and has me questioning whether it's worth shelling out for more exotic foul weather preps. It's UK-made and comprises water-repelling synthetic oils that seep deep into the links and remain firmly ensconced.
Unlike its Teflon cousin, lower viscosity means the oil flows more predictably from the spout, so there's minimal clean up and scant chance of it adorning floors and/or rear wheels.
Spinning the cranks rewards with a refined, squeak banishing serenity pretty much instantly, although derailleur transmissions feel decidedly friskier fed a diet of dry ceramics or PTFE fortified formulas. Thankfully any sensations of stodginess are forgotten within the first couple of miles.
Wet coastal roads are more than capable of dismissing semi-synthetic motor oils within in a matter of hours. Scenic routes through flooded causeways haven't presented any problems, ditto boggy bridle path or long grass.
As you'd expect, mixed terrain jaunts quickly saw side-plates, jockey wheels and cages accumulating that familiar sludgy residue. Wiping these weekly seems sufficient. Everyday asphalt adventures revealed remarkably little contaminant. We've cruised past 230 miles on a single application and I can well believe 500+ given a long dry summer.
Experience suggests ceramics will run slightly cleaner and last longer but they are at least three times the asking price. Salt strewn, slushy winter conditions may reveal some weaknesses, though right now and compared with traditional wet types, I'm struggling to find fault.

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?
'exceptional protection against projected water. Essential for damp conditions!!'
Heavy duty lube for harsh, wet, wintry conditions, mountain biking, cyclo cross etc.
Tell us some more about the technical aspects of the product?
Decathlon are very quiet about exact composition but essentially it's a very stout synthetic and looks suspiciously similar to another British marque.
Stout, low viscosity lube with staying power.
230 miles (and counting!) per mixed terrain application is very impressive. A harsh, slushy winter with salty roads might put a different complexion on things though.
Simple to apply and fits nicely in a saddlebag/larger wedge pack.
Tell us how the product performed overall when used for its designed purpose
Overall, I've been mightily impressed with this wet lube. However, in keeping with the genre, it does attract more dirt, requiring more frequent wiping of the outer links and other drivetrain components to prevent it transforming into a component-gobbling sludgy mess.
Tell us what you particularly liked about the product
Impressive staying power, frugality and bargain price tag.
