Some manufacturers keep things on the low-down before launch date on new components, and we can't blame them -- but when it came to the Campagnolo Super Record 12 EPS Rear Derailleur there was no question that it was coming, the question was instead when' We'd seen it alluded to during the 12-speed mechanical launch, and even raced on by the brand's pro teams, but fortunately for those of us who don't don team jerseys and race in the classics and tours, the groupset is now reaching the public, combining two of the most coveted technologies -- 12-by-2 gearing, and the deliberate crispness of Electronic Power Shift. If we put it lightly, we'd tell you that the Super Record EPS Rear Derailleur is smart, though we'd wager that it would be an understatement. The derailleur operates off of an electronic actuator, comprised of a gear motor and built in resolver sensor. The new derailleur operates in the same fashion as the 11-speed EPS, utilizing an actual that controls a worm screw that takes the place of a mechanical spring screw to move the derailleur. The actuator's resolver sensor is in constant communication with Digital Tech Intelligence -- the brains of the system constantly monitoring and reporting every movement of the derailleur, positioning it optimally relative to the cassette to keep engagement precise and tolerances tight. The derailleur also still maintains EPS Multi-Shift Technology, which enables a shift through eleven of the twelve cogs, either up or down the cassette, in one compression of the shift lever, and in only one-and-a-half seconds. To help alleviate the need for auto-correction, Campagnolo's engineers studied the detrimental effects of vibration on electronic components, and applied T. I. N. treatment to the electronic actuator, keeping titanium parts in tact to maintain performance levels over time, and reduce play. Going further, the engineers also bolstered the strength and rigidity of the derailleur by creating a parallelogram carbon fib..

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
