- Familiarity: I've put it through the wringer
Yes, they are everywhere, but for a good reason; Ultegra derailleurs are amazingly good at moving a chain around. When properly adjusted and maintained, this derailleur sings. This thing shifts faster than you will ever need... perhaps faster. In a word, it is snappy. As an added benefit, it's delightfully quiet. None of that SRAM clickety-clack.
