Do you just not like brifters or are you buying into the "they'll break as soon as you're out of sight of the bike shop" theories?

If the latter, just carry a spare set of DT shifters in your Ortlieb. They couldn't weigh 5 ounces and take up no room. No sense denying yourself the pleasures of Brifters on the off chance they might break.

Of course, if you just don't like brifters, then bar ends or DTs, whichever you prefer.
