Talcum tubes

Having just spent the better part of an hour levering off a Michelin Anakee rear (hooohaaah those babies don't want to give it up), I am reminded of a trick bicycle racers use.

When installing a new tube, they rub it down with talcum powder...make is easier to install, position and remove. Plus it tends to make the tire less inclined to 'grab' the tube and spin it if pressures are low.

I am going to give it a run, as I had quite a time getting the tube out of this beast.

I put a few squirts of the talcum powder in the tire and rotate it to spread the talc before mounting the tire to the rim.

Old bicycle mechanics trick. Cuts down on snakebite flats as well. Use good stuff, 100% cornstarch powder, talc tends to clump while cornstarch does not.

I have a big garbage bag with talc in it. Before fitting the tube, put it in the bag, hold closed but with lots of air in it so the tube has room to tumble as you gently shake it. Carefully remove the tube to avoid clouds of talc escaping. Loosely tie the bag between uses.

Insert the tube without the valve core. After fitting the tyre, inflate the tube to 10 psi then deflate again. This will untwist the tube and let it position itself. Fit the valve core and inflate to seat the bead then drop to required pressure.

I always do that. Also spray soapy water on the bead so the tire will slide down into the rim on the opposite side of where you are levering the tire off the rim. Makes life so much easier. Works for tubes and tubeless tires.
