Effetto Mariposa Carbo Move is an effective penetrating lube designed to be kind to carbon fiber components: think of it as Plus Gas for the composite age. It's sensitive enough to shift stuck-fast carbon goodies without damaging the resins that hold them together, but still has enough penetrating power to free up fasteners you overlooked last winter. It'll even tackle one of those notoriously quick-seize fluted posts beloved of retro road bikes.
Nudging nine quid for 200ml might sound expensive but is a drop in the ocean compared with shop labour or frame repair after brute force component removal.
What we have here, then, is a mightily potent secret formula that goes a very long way if used methodically. A quick squirt is all that's required for removing its companion product Carbo Grip on a properly pampered bike, but neglected winter hacks still call for some appliance of science.
We used Carbo Move to shift a royally stuck alloy post from a steel frame - a lugged & brazed eBay find. The process goes like this. Work somewhere well away from naked flames. Undo the binder bolt and give the Carbo Move a vigorous thirty-second shake. Spray a quick shot around the binder bolt, where the post meets the frame and leave for five minutes or thereabouts.
Get a couple of zip ties and an old jiffy envelope and tear it down the sides. Grab the post (preferably via the saddle) and see if it'll twist free.
No joy? Wrap the old envelope around the post, and secure it with the zip ties. Apply a series of short blasts of Carbo Move at five-minute intervals to the affected area.
By now the solvent should be cascading nicely along the bubble wrap and creeping inside the seat tube.
Leave to penetrate for an hour or so and try again. A quick tap from a rubber mallet can break the corrosive seal, allowing you to wrestle it free.
This technique freed up our stuck post in an hour, but extracting the bottom bracket from a friend's slave bike required an overnight stay, six repeat applications, a quick tap, a long-handled splined tool and lecture on the importance of greasing threaded parts.
Excellent freeing spray and not just for carbon goodies.
