There is something pure about gluing on a set of tubulars. I don't know
maybe its the ritual, but for me it's some kind of connection to the past,
and they have tons of Mojo.
I ride tubulars almost exclusively now. Changing flats on the road isn't all that
much more difficult than a clincher, Roll the old tire off (the difficult part if glued
correctly), mount a preglued spare, pump it up and you are good to go.
It is the pressure that will hold the tire on the rim, not the glue. Just ride easy for
a while, the old glue will still have enough tack to hold the tire in place (so its
stays straight while you pump).
As stated you can't repair a Tufo tire.
The Tufo tape can be used with standard tubulars, but the hold is so tenacious
(and I'm using the regular tufo tape, not extreme) it is easy to pull the
base tape off the carcass of the tire.
