Amen! I put a layer of glue on my tire, another on my rim, and off I go 20 minutes later. Sometimes I skip the new glue on the rim if it's been glued many times. I have *never* rolled a tire and don't understand what all the fuss is about. I use 3M Fasttack and it works simply swell for me. I have ridden for weeks on end on installed-roadside spares.

With Fasttack, I use a single tire lever to get between the tire and rim and pry them apart, working the lever completely underneath the tire then working it around the tire to prevent the base tape from being damaged.

Tubulars rule, no question about it in this youngster's mind <smile>.
