Beats having a tube explod when you're doing 45km/h on a busy city road, losing control of your front wheel with a MACK truck coming up behind you, then almost getting ran over trying to get out of the middle of a 4 lane street. Of course what would i know? that's purely fictional, nothing like that has ever happened to me before and that's not the reason why i switched to tufo's in march.
Carrying the sealant and spare tire bag is so much harder then a spare tube and half a box of tools too
