Carbon Pro Heavy Duty Lube is probably the cleanest running of the truly hell'n'high water lubricants I've tested to date. It has laughed at thunderstorms, river crossings and similar antics. Most surprising of all, it doesn't impair the feel of sportier groupsets.
Unlike its light and middle weight siblings, this one's based upon organic fatty acids derived 'natural feed stocks and additives'. These are designed to provide lubrication, stability and corrosion resistance while resisting dirt and minimising environmental impact.
Another contrast is its consistency, which mimics that of highly refined clear polymer greases and requires concerted effort to apply. However, this minimises waste and is absolutely bang-on for vulnerable fasteners like cleat screws. Indeed, it appears stout enough for installing cartridge bearing bottom brackets or packing hub bearings on fair weather builds!
To my surprise and within a few minutes, it cures to a very clean, almost waxy state with nominal transfer - perfect for post ride fettling or tackling roadside mechanicals. One swift tug of my fixer's pedals saw the chain race serenely for several minutes, every link obviously protected with literally zero overspill. No risk of wheels or flooring becoming the main benefactors here.
Scooting off along the lanes, gear changes were crisp, with a gentle swoosh, even across the Univega's widely spaced cassette. You don't get the responsive urgency of shift afforded by its lower viscosity siblings, but it's streets ahead of most wet formulas.
This is particularly apparent when shifting under load, winching up from granny to outer ring. Settling into a steady 90rpm tempo and charging through the puddles, water seemed to pool atop the links before rolling off, taking any contaminant with it.
Resisting any temptation to wipe the tubby tourers transmission and continuously alternating between salty coastal roads, singletrack and town centres over two weeks had nominal effect either upon its tenure or cleanliness.
Hub and single-speed builds have remained cleaner still and I'm way past three hundred miles from the first application, with little sign of deterioration. All this bodes particularly well for foul weather mountain bike and 'cross meets. However, road salt and other aggressive abrasives may still hold the trump card.
Superior to most wet formulas and may prove very cheap in the longer run
