i've got new carbon tubs coming & i've got Vitorria Corsa Evos to put on. I'll use jantex tape, but i'm going to carry some Pitstop and a spare tub as a backup.

I've got a couple of continental giros....what kind of prep do i need to do to these?
    will the existing tub tape residue on the rim be sufficient to get me home? Should i put new tape on to the spare tub before i go out? should i cary a spare roll of tub tape and put it on if i change the tyre? Is the best idea to carry the spare tub in a bag, usung an old toestrap under the saddle?
